When building a new building or data center, building systems, such as, for example, mechanical systems, electrical systems, plumbing systems, and life safety systems, etc., can be commissioned. In general, commissioning building systems attempts to ensure that the building systems function as intended when released into production.
Examples extend to methods, systems, and computer program products for automatically commissioning an electrical system in industrial/commercial settings (e.g., a data center) to increase the likelihood that the electrical system functions as intended when released into production. Automated data collection devices can collect commissioning data related to electrical and other characteristics of electrical/power system equipment. Automation software can access commissioning data from the automated data collection devices over a computer network. The commissioning data can be stored in a database for analysis. The commissioning data can be compared to pass/fail criteria and a commissioning report can be generated.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
Additional features and advantages will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice. The features and advantages may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features and advantages will become more fully apparent from the following description and appended claims, or may be learned by practice as set forth hereinafter.
In order to describe the manner in which the above-recited and other advantages and features can be obtained, a more particular description will be rendered by reference to specific implementations thereof which are illustrated in the appended drawings. Understanding that these drawings depict only some implementations and are not therefore to be considered to be limiting of its scope, implementations will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
Examples extend to methods, systems, and computer program products for automatically commissioning an electrical system in industrial/commercial settings (e.g., a data center) to increase the likelihood that the electrical system functions as intended when released into production. Automated data collection devices can collect commissioning data related to electrical and other characteristics of electrical/power system equipment. Automation software can access commissioning data from the automated data collection devices over a computer network. The commissioning data can be stored in a database for analysis. The commissioning data can be compared to pass/fail criteria and a commissioning report can be generated.
Implementations may comprise or utilize a special purpose or general-purpose computer including computer hardware, such as, for example, one or more computer and/or hardware processors (including Central Processing Units (CPUs) and/or Graphical Processing Units (GPUs)) and system memory, as discussed in greater detail below. Some computer systems can include and/or be (e.g., network) connected to eye examination devices for examining and/or mapping the human eye. Other devices are also discussed in greater detail below.
Implementations also include physical and other computer-readable media for carrying or storing computer-executable instructions and/or data structures. Such computer-readable media can be any available media that can be accessed by a general purpose or special purpose computer system. Computer-readable media that store computer-executable instructions are computer storage media (devices). Computer-readable media that carry computer-executable instructions are transmission media. Thus, by way of example, and not limitation, implementations can comprise at least two distinctly different kinds of computer-readable media: computer storage media (devices) and transmission media.
Computer storage media (devices) includes RAM, ROM, EEPROM, CD-ROM, Solid State Drives (“SSDs”) (e.g., RAM-based or Flash-based), Shingled Magnetic Recording (“SMR”) devices, Flash memory, phase-change memory (“PCM”), other types of memory, other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store desired program code means in the form of computer-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer.
In one aspect, one or more processors are configured to execute instructions (e.g., computer-readable instructions, computer-executable instructions, etc.) to perform any of a plurality of described operations. The one or more processors can access information from system memory and/or store information in system memory. The one or more processors can (e.g., automatically) transform information between different formats, such as, for example, between any of: commissioning tests, commands, activities, sensed values, commissioning data, pass/fail criteria, forecasted electrical system operation, reports, etc.
System memory can be coupled to the one or more processors and can store instructions (e.g., computer-readable instructions, computer-executable instructions, etc.) executed by the one or more processors. The system memory can also be configured to store any of a plurality of other types of data generated and/or transformed by the described components, such as, for example, commissioning tests, commands, activities, sensed values, commissioning data, pass/fail criteria, forecasted electrical system operation, reports, etc.
A “network” is defined as one or more data links that enable the transport of electronic data between computer systems and/or modules and/or other electronic devices. When information is transferred or provided over a network or another communications connection (either hardwired, wireless, or a combination of hardwired or wireless) to a computer, the computer properly views the connection as a transmission medium. Transmissions media can include a network and/or data links which can be used to carry desired program code means in the form of computer-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer. Combinations of the above should also be included within the scope of computer-readable media.
Further, upon reaching various computer system components, program code means in the form of computer-executable instructions or data structures can be transferred automatically from transmission media to computer storage media (devices) (or vice versa). For example, computer-executable instructions or data structures received over a network or data link can be buffered in RAM within a network interface module (e.g., a “NIC”), and then eventually transferred to computer system RAM and/or to less volatile computer storage media (devices) at a computer system. Thus, it should be understood that computer storage media (devices) can be included in computer system components that also (or even primarily) utilize transmission media.
Computer-executable instructions comprise, for example, instructions and data which, in response to execution at a processor, cause a general purpose computer, special purpose computer, or special purpose processing device to perform a certain function or group of functions. The computer executable instructions may be, for example, binaries, intermediate format instructions such as assembly language, or even source code. Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the described features or acts described above. Rather, the described features and acts are disclosed as example forms of implementing the claims.
Those skilled in the art will appreciate that the described aspects may be practiced in network computing environments with many types of computer system configurations, including, personal computers, desktop computers, laptop computers, message processors, hand-held devices, wearable devices, multicore processor systems, multi-processor systems, microprocessor-based or programmable consumer electronics, network PCs, minicomputers, mainframe computers, mobile telephones, PDAs, tablets, routers, switches, and the like. The described aspects may also be practiced in distributed system environments where local and remote computer systems, which are linked (either by hardwired data links, wireless data links, or by a combination of hardwired and wireless data links) through a network, both perform tasks. In a distributed system environment, program modules may be located in both local and remote memory storage devices.
Further, where appropriate, functions described herein can be performed in one or more of: hardware, software, firmware, digital components, or analog components. For example, one or more application specific integrated circuits (ASICs) can be programmed to carry out one or more of the systems and procedures described herein. In another example, computer code is configured for execution in one or more processors, and may include hardware logic/electrical circuitry controlled by the computer code. These example devices are provided herein purposes of illustration, and are not intended to be limiting. Embodiments of the present disclosure may be implemented in further types of devices.
The described aspects can also be implemented in cloud computing environments. In this description and the following claims, “cloud computing” is defined as a model for enabling on-demand network access to a shared pool of configurable computing resources. For example, cloud computing can be employed in the marketplace to offer ubiquitous and convenient on-demand access to the shared pool of configurable computing resources (e.g., compute resources, networking resources, and storage resources). The shared pool of configurable computing resources can be provisioned via virtualization and released with low effort or service provider interaction, and then scaled accordingly.
A cloud computing model can be composed of various characteristics such as, for example, on-demand self-service, broad network access, resource pooling, rapid elasticity, measured service, and so forth. A cloud computing model can also expose various service models, such as, for example, Software as a Service (“SaaS”), Platform as a Service (“PaaS”), and Infrastructure as a Service (“IaaS”). A cloud computing model can also be deployed using different deployment models such as private cloud, community cloud, public cloud, hybrid cloud, and so forth. In this description and in the following claims, a “cloud computing environment” is an environment in which cloud computing is employed.
In this description and the following claims, “polyphase electrical power” is defined as electrical power having a plurality of energized electrical conductors (e.g., two, three, four, etc.) carrying alternating currents with a defined time offset between the voltage waves in each conductor.
In this description and the following claims, “three-phase electrical power” is defined as electrical power having three energized electrical conductors (a “3-wire configuration”) carrying alternating currents with a defined time offset between the voltage waves in each conductor. For symmetric three-phase electrical power, each of three conductors can carry alternating current (AC) of the same frequency and voltage amplitude relative to a common reference but with a phase difference of one-third the period. The common reference can be connected to ground and/or can be connected to a current-carrying conductor (e.g., the neutral). Due to the phase difference, the voltage on any conductor reaches its peak at one third of a cycle after one of the other conductors and one third of a cycle before the remaining conductor. The phase delay gives constant power transfer to a balanced linear load. Three-phase electrical power can be connected in a variety of different ways, including: a Wye (Y) (or “star”) configuration, a Delta (Δ) configuration, etc.
In this description and the following claims, “a wye (Y) (or “star”) connection” is defined as a connection where one end of a conductor for each phase are commonly connected.
In this description and the following claims, “a delta (Δ) connection” is defined as a connection where, per phase, each end of a conductor for the phase is connected to an end of a conductor for each of the other phases. That is, loads are connected across the lines, and so loads see line-to-line voltages.
As described for Delta (Δ) configurations, loads are connected across the lines, and so loads see line-to-line voltages. Equation 171 defines voltage V12 (at point 181), equation 172 defines voltage V23 (at point 182), and equation 173 defines voltage V31 (at point 183). VLN is line voltage.
Both a delta (Δ) connection and a wye (Y) connection can be arranged in a “4-wire” configuration wherein a fourth wire is provided as a neutral and can be grounded. “3-wire” and “4-wire” configurations can also include a ground wire for fault protection.
Power Transmission and Distribution
In this description and the following claims, “electric power transmission” is defined as bulk movement of electrical energy (e.g., three-phase power) from a generating site (e.g., a power plant) to an electrical substation. Interconnected lines facilitating transmission of electrical energy are known as a transmission network. Power can be transmitted at various different voltages. At power stations, power is produced at a relatively low voltage between about 2.3 kV AC and 30 kV AC, depending on the size of the unit. The generator terminal voltage is then stepped up by a power station transformer to a higher voltage (e.g., 110 kV AC to 765 kV AC, varying by the transmission system and by the country) for transmission over longer distances. In the United States, power transmission is, variously, 230 kV to 500 kV AC, (e.g., 230 kV AC, 345 kV AC, etc.) with some power transmission of less than 230 kV AC (e.g., 115 kV AC, 138 kV AC, 161 kV AC) or more than 500 kV AC (e.g., in localized areas). In some aspects of the invention, voltages over 765 kV AC utilize different designs compared to equipment used at lower voltages.
In this description and the following claims “electric power distribution” is defined as the movement electrical energy (e.g., three-phase power) from an electrical substation to customers. Interconnected lines which facilitate distribution of electrical energy are known as a distribution network. Distribution substations connect to a transmission system (or subtransmission system) and lower the transmission voltage to medium voltage ranging, for example, between 2 kV AC and 35 kV AC, with the use of transformers.
Primary distribution lines carry this medium voltage power to distribution transformers located near customer's premises. Distribution transformers again lower the voltage to the utilization voltage of household appliances and typically feed several customers through secondary distribution lines at this voltage. Commercial and residential customers are connected to the secondary distribution lines through service drops. Customers demanding a larger amount of power, for example, for industrial or data center applications, may be connected directly to the primary distribution level or the subtransmission level.
Subtransmission (e.g., of three-phase power) is part of an electric power transmission system that runs at relatively lower voltages. It may be uneconomical to connect all distribution substations to a higher main transmission voltage, because the equipment is larger and more expensive. Typically, only larger substations connect with this higher voltage. The higher voltage can then be stepped down and sent to smaller substations in towns and neighborhoods.
There is no fixed cutoff between subtransmission and transmission, or between subtransmission and distribution. The voltage ranges can overlap. Voltages of 69 kV AC, 115 kV AC, and 138 kV AC are sometimes used for subtransmission in North America. As power systems have evolved, voltages formerly used for transmission were transitioned for subtransmission, and voltages formerly used for subtransmission were transition for distribution voltages. Like transmission, subtransmission can move relatively large amounts of power, and like distribution, subtransmission can cover an area instead of just point to point. At substations, transformers reduce the voltage to a lower level for distribution to commercial and residential users. This distribution can be accomplished with a combination of subtransmission (33 kV AC to 132 kV AC) and distribution (3.3 kV AC to 33 kV AC).
At the point of use, the electrical energy (e.g., three-phase power) is transformed to lower voltage, for example, “Mains electricity” (varying by country and customer requirements). Within the Americas 60 Hz AC, a 120/240 volt split phase system can be used domestically and three phase for larger installations.
In this description and the following claims, the “power grid” or simply the “grid” is defined as a combined transmission network (including any optional subtransmission networks) and distribution network.
Transmission customer 204 can access the transmitted power from transmission lines 203. Transmission customer 204 can include additional transformers and other electrical equipment and/or power system equipment for utilizing transmission range voltages (e.g., 110 kV AC to 765 kV AC). Transmission customer 204 may represent an interconnection between a grid containing generating station 201 and some other grid. For example, in North America, transmission customer 204 can represent an interconnection between any of: the Eastern Grid, the Western Grid, the Texas (ERCOT) Grid, the Alaska Grid, and the Quebec Grid.
Substation step down transformer 206, for example, in subtransmission systems 207, can step down the transmission voltage to a voltage in the range of 33 kV AC to 132 kV AC. Voltage in the range of 33 kV AC to 132 kV AC can be transmitted over transmission lines within subtransmission systems 207. In one aspect, multiple subtransmissions systems transmit different voltages. The voltages can be progressively stepped down as equipment is physically located closer to residential and commercial end users. Subtransmisson customer 208 (e.g., a data center or industrial user) can access the transmitted power from transmission lines. Subtransmission customer 208 can include additional transformers and other electrical/power system equipment for utilizing voltages in the 26 kV AC to 132 kV AC range.
Substation step down transformer 213 can further step down voltages transmitted through subtransmission systems 207 to a voltage in the range of 4 kV AC to 69 kV AC for distribution on distribution lines 214. Subtransmission customer 209 (e.g., an industrial or data center customer) can access the distributed power from distribution lines 214. Subtransmission customer 209 can include additional transformers and other electrical/power system equipment for utilizing voltages in the 26 kV AC to 69 kV AC range. Primary customer 211 can also access the distributed power from distribution lines 214. Primary customer 211 can include additional transformers and other electrical/power system equipment for utilizing voltages in the 4 kV AC to 13 kV AC range.
Step down transformer 216 can further step down voltages on distribution lines 214 for commercial and/or residential use. For example, step down transformer 216 can step down voltages on distribution line 214 to 240V AC (and/or 120V AC). Secondary customer 212 (e.g., a residence) can access the 240V AC (and/or 120V AC) from step down transformer 216.
Building System Commissioning
When constructing a building or data center, mechanical, electrical, plumbing, and life safety systems are designed to operate in an intended manner when released into production. However, there is no way to ensure that a particular system operates in an intended manner until the system is actually constructed. Even the best designs may not be realized in a system that operates as intended. As such, a commissioning process for individual building systems can be used to validate building system performance prior to production release of the building system (e.g., prior to turning the building over to an owner, allowing the building to be used for an intended purpose, such as, housing servers, etc.). Commissioning various building systems helps insure that the building systems function as intended when released into production.
Commissioning processes have remained largely static over the last half century. Commissioning a building system includes developing a commissioning plan. Human commissioning agents review and comment on the plan. Commissioning test scripts are developed and reviewed. A construction QA/QC process is witnessed and equipment is inspected. An installer or manufacturer starts up the equipment. A commissioning team (of human commissioning agents) connects test devices to the equipment. The commissioning team operates the equipment through various conditions. The commission team gathers data and, from the data, determines if the building system passes or fails. The commissioning team can generate and submit a report of their findings.
There are several deficiencies in the manually intensive process for building system commissioning. Many of the deficiencies relate to safety, human error, and efficiency. Commissioning agents are human which can cause safety issues and inconsistent results across the program. Deficiencies include, but are not limited to, (1) errors and non-standardization in test development, (2) errors in equipment inspection, (3) errors in test execution and performing testing processes, (4) errors when collecting and analyzing results, (5) errors in report preparation, and (6) errors when explaining results.
More specifically, commissioning electrical systems in industrial/commercial settings, such as, for example, in data centers, can increase the likelihood that the electrical system functions as intended when released into production. Electrical system commissioning can include human commissioning agents physically going to various different pieces of electrical equipment (e.g., transformers, generators, switch gear, relays, circuit breakers, bus bars, batteries, alternators, equipment (e.g., server) racks, etc.) of the electrical system. The commissioning agents can attempt to record electrical characteristics (e.g., voltage changes, current changes, transients, harmonics, ground faults, short circuits, etc.) of the electrical equipment under different test conditions (e.g., energized from utility, energized from generator, switching from utility to generator, switching from generator to utility, different loads, etc.).
Similar to other types of commissioning, when commissioning an electrical system, any results are subject to human error. Electrical system commissioning is also human capital intensive, since many commissioning agents may be required.
Additionally, when commissioning electrical system equipment, such as, for example, when working with electrical and energy isolation, various safety considerations also arise. There is a safety risk when connecting testing devices to electrical system equipment. There is a safety risk when operating electrical system equipment. There is a safety risk when removing testing devices from electrical system equipment.
As such, many electrical system commissioning activities are dangerous and/or are considered High Risk Activities (“HRAs”) due to the voltages under test (e.g., up to 10s of thousands of volts). A human commissioning agent is often required to open (e.g., remove protective panels on) electrical equipment to access internal electrical connections. The electrical connections can remain exposed while commissioning tests are performed. For example, it might not be possible to reattach protective panels prior to testing due to wires going from inside equipment to externally connected test devices.
The voltages present in industrial applications, data centers, etc. pose an increased risk of injurious and potentially lethal shock if mistakes are made during commissioning. For example, difficulty breathing, pain, and muscle paralysis can occur when a person receives a shock between 10 milliamps and 100 milliamps. Increased risk of ventricular fibrillation (resulting in death) can occur when a person receives a shock between 100 milliamps and 200 milliamps Severe burns and breathing cessation (resulting in death) can occur when a person receives a shock over 200 milliamps.
Automated Electrical System Commissioning
In one aspect, a commissioning center computer system is connected to a plurality of automated data collection devices over a (e.g., wired and/or wireless) network to form a commissioning automation network (CAN). A CAN can be a temporary network deployed to support commissioning activities through applying automation to the commissioning process. Deploying a CAN can include deploying automation software to control and monitor multiple pieces of electrical equipment as well as deploying test equipment, data loggers, cameras, condensers (microphones), etc. Outputs from test equipment, data collection devices, cameras, condensers, etc. can be delivered over a wired and/or wireless network for rendering at a commissioning center computer system.
Each of a plurality of automated data collection devices can collect data related to electrical system commissioning. Some devices are electrically connected to (e.g., directly to conductors within) electrical system equipment and others monitor environmental conditions related to electrical system equipment functionality. Devices connected (e.g., directly) to electrical system equipment can include sensors and/or circuitry for collecting data related to electrical characteristics of the electrical system equipment (e.g., voltage changes, current changes, transients, harmonics, ground faults, short circuits, etc.). Devices monitoring environmental conditions can collect data, such as, for example, heat, temperature, humidity, barometric pressure, etc. in environments around pieces of electrical system equipment. Other devices, such as, cameras and condensers can capture video and audio in environments around electrical system equipment.
Commissioning automation software at the commissioning center computer system collects data from each of the automated data collection devices over the network. The data can be used to automatically establish pass/fail for various commissioning tests (without a human being near potentially dangerous electrical system equipment). The data can also be stored in a database for subsequent analysis (e.g., used by operations teams, used as feedback to tailor subsequent commissioning tests, sent to commissioning supervisors, etc.). Once the data is stored, analysis possibilities are very diverse.
In another aspect, a commissioning center computer system provides collected data and test results to a commissioning agent or other user through a user-interface. The commissioning agent or other user can view collected data and test results in essentially real-time and make decisions (e.g., start other tests, sign-off, etc.) through the user-interface based on the collected data and test results.
An electrical system commissioning process can be highly (e.g., potentially fully) automated by integrating data collection, control, analysis and reporting of the testing and results. Commissioning Automation Testing software (CATS) can operate over a CAN to control, monitor, and record data from the test equipment as well as portions of building infrastructure. Results are captured and analyzed by the CATS. Results that fall outside of the acceptable parameters can be reported as a failed condition by the software.
By using automation software, pre-set equipment performance parameters can be selected. When running the tests, CATS can gather the data, analyze the results, compare against the pre-set pass fail criteria, and automatically generate a pass/fail report. This automation provides real time analysis of the results. CATS can control and monitor the electrical system equipment under test, capture the data, analyze the results, and then place the required data and results in a final report. Automating data capture and analysis drastically reduces the time the required for a commissioning agent to download the data, analyze the data, and decide what data needs to go into a commissioning report. It also increases safely by reducing the time commissioning agents work around energized electrical system equipment.
During commissioning of various industrial and/or commercial installations, such as, for example, data centers, 100,000s of data points can be collected. Automation and (big) data analysis can be used to identify trends in collected data. By capturing data and storing data in a (potentially distributed) database, the data can be analyzed using (big) data business intelligence tools.
CATS can also integrate building systems and commissioning equipment to a single platform. By running commissioning tests through automated software, results consistency is increased by ensuring the tests are run the same way (and reducing the likelihood of human error). Safety is also improved, by removing commissioning agents from some of the hazards during the testing. By connecting commissioning equipment and installed electrical equipment, many data points (e g, millions) are captured and (e.g., near) real-time performance analysis of performance can be realized. When analysis is completed and pass/fail conditions are reported, a commissioning center computer system can automatically generate a commissioning report.
Accordingly, aspects of the invention include automatically commissioning an electrical system in industrial/commercial settings (e.g., a data center) to increase the likelihood that the electrical system functions as intended when released into production. Automated data collection devices can collect commissioning data related to electrical and other characteristics of electrical equipment. Automation software can access commissioning data from the automated data collection devices over a computer network. The commissioning data can be stored in a database for analysis. The commissioning data can be compared to pass/fail criteria. A commissioning report can be generated.
In other aspects, a commissioning center computer system controls and monitors electrical system equipment being commissioned. In an automated fashion, the commissioning center computer system captures commissioning data, analyzes results, places the commissioning data in a database, and generates reports. The commissioning center computer system can send commands to automated data collection devices to perform various commissioning activities, for example, run a specific script, perform a commissioning test or tests on a piece of electrical system equipment, etc.
In one aspect, if commissioning data for a piece of electrical system equipment does not satisfy pass/fail criteria, a commissioning center computer system automatically sends commands to automated data collection devices to perform additional commissioning activities.
Power lines 321, step down transformer 322, and power lines 361 can be included in power transmission system and/or power distribution system that is external to data center 301. Power lines 321 can be carrying three-phase power at a first voltage (e.g., in a range between 33 kV AC to 132 kV AC). Step down transformer 322 can step down the three-phase power at the first voltage to three-phase power at a second lower voltage (e.g., in a range between 3.3 kV AC to 33 kV AC). Power lines 361 can carry the three-phase power at the second lower voltage into data center 301. Other voltages ranges for power lines 321 and power lines 361 are also contemplated.
Electrical system 323, monitoring device network 327, and commissioning system 302 can be included in data center 301. Power lines 321 and step down transformer 322 can be under the control of a first entity (e.g., a power or utility company) and data center 301 can be under the control of second different entity (e.g., a different business). Power lines 361 may be under the control of either the first or second entity depending on a power distribution arrangement between the first and second entities. Power lines 321 and/or step down transformer 322 can be part of a substation, which may or may not be physical located on property under the control of the second entity. Power lines 361 can be fully physically located on property under the control of the second entity or partially physically located on property under the control of the second entity and partially physically located on other property (e.g., depending on the location of a substation).
During design of data center 301, a designer (e.g., owner) can desire for electrical system 323 to operate in an intended manner. For example, the designer can desire for electrical system 323 to safely provide a stable power source for servers installed (e.g., in server racks) at data center 301 under a variety of different operating conditions. The variety of different operating conditions can include, but are not limited to: energized from utility, energized from generator, switching from utility to generator, switching from generator to utility, different loads, etc.
As depicted, electrical system 323 includes pieces of electrical equipment 324A-324D operating in environments 326A-326D respectively. Electrical equipment 324A-324D can include any of a variety of different types of electrical/power system equipment, such as, for example, transformers (e.g., additional step down transformers), generators, switch gear, relays, circuit breakers, bus bars, batteries, alternators, server racks, etc. Several other pieces of electrical equipment, in addition to electrical equipment 324A-324D, can also be included in electrical system 323. As such, electrical system 323 can include hundreds, thousands, or even tens of thousands of pieces of electrical equipment.
Electrical system 323 can be part of a power system infrastructure for powering data center 301.
Monitoring device network 327 includes devices 328A-328E. Devices in monitoring device network 327 can be configured to monitor electrical characteristics of electrical equipment in electrical system 327 as well as monitor other (e.g., environmental) characteristics associated with the operation of electrical equipment in electrical system 327. Several other monitoring devices, in addition to devices 328A-328E, can also be included in monitoring device network 327. As such, monitoring device network 327 can include hundreds, thousands, or even tens of thousands of monitoring devices.
Devices in monitoring device network 327 can be connected to commissioning system 302, and possibly to one another (e.g., in a mesh network or star network arrangement), via wired and/or wireless computer network connections. Devices in monitoring device network 327 can also include sensors and, when appropriate, other relevant connections for formulating commissioning data for monitored pieces of electrical system equipment and monitored environments.
For example, some devices in monitoring device network 327 can have direct electrical connections to conducting wires inside pieces of electrical equipment in electrical system 323. These devices can include sensors for sensing electrical characteristics of electricity on the conducting wires under different test conditions (e.g., energized from utility, energized from generator, switching from utility to generator, switching from generator to utility, different loads, etc.). Sensed electrical characteristics can include voltage changes, current changes, transients, harmonics, ground faults, short circuits, etc., under one or more of the different test conditions. These devices can also include computing resources (software and/or hardware) for transforming, converting, etc. sensed electrical characteristics into commissioning data indicative of the sensed electrical characteristics.
Other devices in monitoring device network 327 can monitor environmental conditions around pieces of electrical equipment under different test conditions (e.g., energized from utility, energized from generator, switching from utility to generator, switching from generator to utility, different loads, etc.). Sensed environmental conditions can include heat, temperature, humidity, barometric pressure, images, sounds, etc., under one or more of the different test conditions. These devices can also include computing resources (software and/or hardware) for transforming, converting, etc. sensed environmental conditions into commissioning data indicative of the sensed environmental conditions.
In one aspect, multiple devices can be used to monitor different characteristics/conditions associated with a piece of electrical equipment. For example, device 328A can be electrically connected to conducting wires within equipment 324A to monitor electrical characteristics of electricity on the conducting wires. Device 328B can be placed in environment 326A to monitor environmental conditions around equipment 324A. Under one or more different test conditions, device 328A can monitor electrical characteristics of electricity on the conducting wires of equipment 324A along with device 328B monitoring environmental conditions in environment 326A. Device 328A can also include computing resources (software and/or hardware) for transforming, converting, etc. sensed electrical characteristics on the conducting wires within equipment 324A into corresponding commissioning data indicative of the sensed electrical characteristics. Device 328B can also include computing resources (software and/or hardware) for transforming, converting, etc. the sensed environmental conditions in environment 326A into commissioning data indicative of the sensed environmental conditions.
Alternately, multiple devices can be electrically connected to conducting wires within equipment to monitor different electrical characteristics. For example, both device 328C and 328D can be electrically connected to conducting wires within equipment 324B. Under one or more different test conditions, each of devices 328C and 328D can monitor different electrical characteristics of electricity on the conducting wires. For example, device 328C can monitor voltage and current while device 328D monitors harmonics. These devices can also include computing resources (software and/or hardware) for transforming, converting, etc. sensed electrical characteristics on the conducting wires within equipment 324B into commissioning data indicative of the sensed electrical characteristics.
In an additional alternative, multiple devices can be used to monitor environmental conditions around a piece of electrical equipment. For example, both device 328B and 328E can be placed in environment 326B. Under one or more different test conditions, each of devices 328B and 328E can monitor different environmental conditions in environment 326B. For example, device 328B can monitor temperature and device 328E can monitoring humidity. These devices can also include computing resources (software and/or hardware) for transforming, converting, etc. sensed environmental conditions in environment 326B into commissioning data indicative of the sensed environmental conditions.
In another aspect, a device can be used to monitor characteristics and/or conditions associated with multiple pieces of electrical equipment. A device can include multiple sensors can that be placed in different locations. For example, device 328B may include multiple temperature sensors. Once sensor can be placed in environment 326C and another sensor can be placed in environment 326D. Under one or more different test conditions, device 328B can monitor temperature in both environment 326C and environment 326D.

In general, monitoring device types, arrangements, and combinations can be tailored to capture commissioning data relevant to an electrical system being commissioned.
As depicted, commissioning system 302 includes control module 303, storage device 304, and commissioning tests 306. In general, control module 303 can send commands to devices in monitoring device network 327 over a wired or wireless computer network. The commands can instruct devices to monitor electrical equipment and formulate commissioning data for electrical equipment and environments within electrical system 323.
In some aspects, control module 303 can also perform activities within an electrical system 323 to change test conditions. In other aspects, control module 303 sends commands to devices in monitoring device network 327. The monitoring devices then perform activities within an electrical system 323 to change test conditions. In further aspects, test conditions can be changed by a human commissioning agent or other personnel.
Commissioning data formulated at devices in monitoring device network 327 can be sent to commissioning system 302 over a computer network. Commissioning system 302 can receive the commissioning data from monitoring device network 327. Commission system 302 can store the commissioning data at storage device 304 (e.g., at a database).
An operator of commissioning system 302 (e.g., a commissioning agent) may desire to commission electrical system 323 for release into production. The operator can enter commands into commissioning system 302 through a (e.g., graphical) user-interface. In response, commissioning system 302 can attempt to commission electrical system 323.
Method 400 includes accessing commissioning tests tailored for commissioning an electrical system for release into production (401). For example, control module 303 can access commissioning tests 306. Commissioning tests can be tailored (e.g., by a commissioning agent) for commissioning electrical system 323. That is, commissioning tests 306 can be specifically configured to commission types of electrical equipment and environments included in electrical system 323. Control module 303 can access commissioning tests 306 from a durable storage device or from system memory at commissioning system 302.
Method 400 includes formulating commands for configuring a plurality of monitoring devices from the accessed commissioning tests, the formulated commands for configuring the plurality of monitoring devices to monitor characteristics associated with operation of one or more of a plurality of pieces of electrical equipment under one or more different test conditions (402). For example, control module 303 can formulate commands 308 from commissioning tests 306. Commands 308 can be for configuring a plurality of devices in monitoring device network 327 to monitor characteristics associated with operation of electrical equipment in electrical system 323. Monitoring can occur under one or more different test conditions (e.g., energized from utility, energized from generator, switching from utility to generator, switching from generator to utility, different loads, etc.).
For each of the one or more of the plurality of monitoring devices, method 400 includes sending a formulated command to the monitoring device, the formulated command instructing the monitoring device to monitor one or more characteristics associated with operation of one or more of the plurality of pieces of electrical equipment under the one or more different test conditions (403). For example, control module 303 can send command 308A (from commands 308) to device 328A. Command 308A can instruct device 328A to monitor humidity in environments 326A and 326B under the one or more different test conditions. Similarly, control module 303 can send command 308B (from commands 308) to device 328D. Command 308B can instruct device 328D to monitor voltage and current of electricity on conducting wires inside equipment 324C under the one or more different test conditions.
Method 400 includes receiving the command from the commissioning system (404). For example, device 328A can receive command 308A from control module 303. Similarly, device 328D can receive command 308 B from control module 303.
Method 400 includes monitoring the one more pieces of electrical equipment under the one or more different test conditions to sense values for each of the one or more characteristics associated with operation of each of the one or more pieces of electrical equipment (405). For example, device 328A can monitor environments 326A and 326B to sense humidity values 312A in environments 326A and 326B during operation of equipment 324A and 324B under the one or more different test conditions. Device 328D may have a direct electrical connection to conducting wires inside equipment 324C. Device 328D can monitor the conducting wires inside equipment 324C to sense voltage and current values 312B of electricity on the conducting wires under the one or more different test conditions.
Other commands from commands 308 can be sent to and received at other devices (e.g., device 328B, 328C, 328E, etc.) in monitoring device network 327. The other commands can instruct the other devices to monitor other characteristics associated with the operation of equipment 324A-324D under the one or more different test conditions. Thus, in general, monitoring device network 327 can monitor 310 electrical systems 323 under the one or more different test conditions.
Different test conditions within data center 301 can be cycled by commissioning agents or in an automated manner by a combination of commissioning system 302 and/or devices included in monitoring device network 327. For example, a commission agent can switch some or all of electrical system 323 from generator to utility power or vice versa. Alternately, control module 303 can send activities 307 to electrical system 323 to switch some or all of electrical system 323 from generator to utility power or vice versa. In a further alternative, devices in monitoring device network 327 can send activities 309 switch some or all of electrical system 323 from generator to utility power or vice versa. Other transitions between different test conditions within data center 301, for example, changing loads on parts of electrical system 323, can be similarly facilitated.
Commissioning data can be collected under one test condition, the test conditions changed, and commissioning data again collected. Testing conditions can be changed multiple times and commissioning data collected for each test condition. In one aspect, commissioning data is collected when electrical system 323 is under each of a plurality of different loads. In another aspect, commissioning data is collected when electrical system 323 is energized from utility, during transition of electrical system 323 from utility to generator, when electrical system 323 is energized from generator, and during transition of electrical system 323 from generator to utility. Looping behavior can be implemented, wherein different commissioning data is collected on each loop iteration.
Method 400 includes transforming the sensed values into commissioning data, the commissioning data indicative of the sensed values (406). For example, device 328A can transform sensed values 312A into commissioning data 313A. Similarly, device 328D can transform sensed values 312B into commissioning data 313B.
Method 400 includes sending the commissioning data to the commissioning system for use in analysis and reporting to determine the likelihood of the electrical system operating as intended when released into production (407). For example, device 328A can send commissioning data 313A to commissioning system 302. Similarly, device 328D can send commissioning data 313B to commissioning system 302. Commissioning data 313A and 313B can be used for determining the likelihood of electrical system 323 operating as intended when released into production.
For each of the one or more of the plurality of monitoring devices, method 400 includes receiving commissioning data from the monitoring device (408). For example, commissioning system 302 can receive commissioning data 313A and 313B from devices 328A and 328D respectively.
Other devices (e.g., device 328B, 328C, 328E, etc.) in monitoring device network 327 can also transform sensed values (e.g., temperature, harmonics, etc.) into commissioning data. The other devices can send the commissioning data to commissioning system 302. Commissioning system 302 can receive the commissioning data from the other devices.
For each of the one or more of the plurality of monitoring devices, method 400 includes storing the commissioning data in a database for subsequent analysis and reporting to determine the likelihood of the electrical system operating as intended when released into production (409). For example, commissioning system 302 can store commissioning data 313A and 313B, as well as other commissioning data received from any other devices in monitoring device network 327, at storage device 304 (e.g., a durable storage device). Commissioning data 313A and 313B, as well as the other commissioning data, can be stored in a database table. Commissioning data 313A and 313B, as well as the other commissioning data, can be stored for subsequent analysis and reporting to determine the likelihood of electrical system 323 operating as intended when released into production. Commissioning data 313A and 313B, as well as the other commissioning data, can be aggregated into commissioning data 313.
