This disclosure relates to assembly of control panels. More particularly, this disclosure relates to assembly of discrete modules of a control panel that can be independently wired, tested, and installed into a control panel.
Control panels are used in utility, industrial, and military installations to house various control, automation, metering, and protection components that pertain to operation of an electrical power system. A key function of control panels often is to present these components for use by personnel. The various components may be housed such that interfaceable portions are visible and readily available to be viewed and used by personnel. The control panel components are often arranged and wired together (and to other hardware or other control panels) according to an application of a site. Such wiring may be housed within the control panel, and often behind the face of the panel, and not seen or directly accessible by personnel.
Often the application of a control panel can be particular and/or unique to the site, such that there is high variability in design and use of control panels. Every site participating in operation of an electrical system is a little bit different. The connection to the electrical power system may be unique for a variety of reasons, including other control panels already installed at the site, the era of construction of the site and/or the adjacent portion of the electrical power system, the existing hardware at the site, and/or the background, experience, and/or preferences of the individuals to be acting as operators at the site. All these factors create highly variable needs, uses, and applications (e.g., collections of functions) to be addressed by control panels, and therefore there is high variability in use and application of control panels, which has led to similarly high variability in the processes of designing and assembling control panels.
For example, while some conventional panels used in some electric utilities measure around 2′×7′×3′, the size of panels within electric utilities can vary by around 50%, even in the same utility. In addition to size variability, the components that may be included in and housed in control panels can vary widely. For example, a control panel used by an electric utility may include one or more intelligent electronic devices (IEDs) used for protection, control, automation, and/or metering of electric power equipment, automation controllers, test contacts, human-machine interfaces (HMIs), industrial computers, accurate clocks, communication devices, pushbuttons, switches, status indicators, Deutsches Institut fur Normung (DIN) rails, terminal blocks, cable routing, breakers, and the like.
The high degree of variability of control panels has resulted in presently available processes, prior to the present disclosure, that are inefficient and defect prone. Presently available processes require long lead times for engineering and design before actual assembly of the control panel can be performed. Control panels require electronic design and engineering that require specialized skills that can be a challenge to recruit in today's workforce. Prior to the present disclosure, every custom (e.g., site-specific) control panel would require a custom design from a specialized, highly skilled team, requiring a higher skill level of drafters, engineers, coders, and testers at every step of the design. Sufficiently skilled persons are not readily available to hire and, when they can be found, training these persons takes years.
The actual build time of control panels is also presently long because the high degree of variability of components is such that components cannot be easily maintained on hand and generally must be procured after initial engineering and design of a control panel. The actual build time of control panels is also presently long, partly caused by congestion due to the physical constraints of a control panel frame that limit more than one person at a time from working on assembly (e.g., wiring) of a control panel. These physical constraints affect the time required to mount, wire, and test a control panel.
To effectively handle the variability presented and presently required, control panel design and assembly requires a nimble, large, and highly skilled workforce that adapts to customized/unique ordering, manufacturing, shipping/packaging, installation, testing, and maintenance procedures, and delivery of a site-specific control panel. Even with a highly skilled and highly trained work force, it can take several months to engineer and design and then to assemble a control panel, and the defect rate in control panels assembled through presently available processes has been too high.
Control panel design and assembly therefore introduces and involves challenges related to cost control, quality control, time-intensive engineering rework, re-wiring, and documentation tracking, inventory management, and procurement of components.
The electrical power system industry would like to be able to design, engineer, produce, and otherwise have more readily available the types of control panels that pertain to operation of electrical power systems. Lower lead times for ordering and installing new control panels would enhance the industry. As in any assembly situation, there is interest to create repeatable and predictable processes that can drive up quality and drive down defects.
The uniqueness of each control panel site and application need at that site, and therefore the uniqueness and variability of each implementation of a control panel, presents significant challenges to developing more efficient, repeatable, lower-error rate assembly solutions. The uniqueness and variability have also perpetuated other present challenges to efficient and repeatable processes of designing and assembling control panels. The engineering time presently invested into a control panel is generally insufficient to design a repeatable, low error rate solution. Control panel design documentation is typically insufficiently mature to fully optimize all facets of the design. De-conflicting space congestion or mounting and wiring can be problematic in control panels. Custom control panels are, in effect, considered in the industry to be always in a prototype-like stage.
Specifically, with respect to assembly of control panels, physical parameters and constraints present significant limitations to the assembly process. Because the common dimensions of a panel may extend from ground level to around seven feet tall, the assembly process may include installation of components and wiring well above head-level of the assembly personnel. This introduces several possible sources of injury and strain. Furthermore, because many components may be installed into a single panel, multiple personnel may be needed to work in a single panel to assemble and wire the several components. This introduces physical strain, and increases the time necessary for assembly. Build times of panels may be long, partly caused by congestion of the physical constraint limiting more than one person at a time from wiring in the panel. This affects the time required to mount, wire, and test the panel.
Once a panel has been designed, assembled, and put into use, it may become desirable to update or upgrade the panel or components therein. Control panels that follow the typical design and assembly may be difficult to modify due to the integration of the components in the panel. That is, typical control panels are difficult to upgrade. Older control panel design and assembly methods require customized re-design and modification as the electric power system evolves and upgrades become desirable. For example, many protection and control strategies are expected to change over the next few decades to accommodate distributed energy such as photovoltaic, batteries, and wind. The existing infrastructure was not designed for such rapid changes and upgrades are time consuming and error prone when associated with unique designs.
The present inventors have recognized the desirability of improved assembly processes, systems, devices, and methods to resolve the problems with presently available custom panel design and assembly as described above.
The present disclosure and descriptions herein relate to defining and assembling modules that are a self-contained solution to an electrical function pertaining to operation of an electrical power system, and that can be independently wired, tested, and installed to assemble a control panel. The systems methods and techniques disclosed allow for high predictability and repeatability of design and assembly at a modular level while affording customization and variability at the control panel level.
The present disclosure includes pre-defining modules with a module definition that includes data specifying: components to perform the electrical function; mechanical arrangement of the components; electrical connections, including connections between the components and points of interface with other modules and other equipment of the power system; and logical interactions of the module, including logical connections between the components and logical interfaces with other modules or other equipment of the power system.
The module definitions afford an ability to receive from a customer, an operator, an engineer, or other requester a designation of a set of modules to be included in a control panel to be assembled. In some embodiments, the designation of a set of modules is received at a computing system. Those modules can be pre-manufactured and stocked in inventory or they can be more readily ordered and/or manufactured, thereby decreasing required lead time to ultimately install a control panel. For example, a bill of materials (BoM) can be prepared or otherwise generated based on the designated modules. In some embodiments, a computing system can automatically prepare or otherwise generate a BoM based on the designated modules and the definitions thereof. The BoM can include a listing of all components of every module of the designated set of modules. Stated differently, the BoM can specify a parts list that includes a part listing for each of the one or more components of all the modules in the set of modules designated. The BoM is to be used to order the components according to each part listing in the parts list.
The module approach to assembling control panels can afford an ability to independently wire each module and thereby increase throughput. Rather than assembling all components of a control panel in a control panel frame, as has traditionally been done, the individual modules can be assembled independently, such as at different locations and/or different points in time, using one or more module assembly frames. Thus, a control panel comprising a plurality of modules (e.g., four modules) can be assembled by assembling the plurality of modules in parallel with a plurality of workers (e.g., four workers) independently wiring each of the plurality of modules. The assembly time is drastically reduced.
The module approach to assembling control panels can afford an ability to have repeatability in manufacturing or assembly of the modules, which can lower costs and defect rates. The assembly of a defined module can be a repeatable process that can be refined to remove errors and lower the defect rate (if not eliminate defects entirely). The repeatability of the process also opens opportunity for a workforce that has less experience and/or skill (at least lesser than may be needed for a process that is, in essence, creating a custom panel every time).
The present disclosure and descriptions herein also relate to modularly assembled control panels that are assembled using one or more pre-defined and independently wired and discretely functioning modules. A set of modules is designated for assembly into a control panel. The set of modules may be designated for the panel, such as by a user, customer, engineer, or a control panel definition.
The present disclosure and descriptions herein also relate to reusable assembly frames that may be used as a sub-assembly station for independently assembling modules for inclusion in a control panel. A module can be assembled at the assembly frame, including arranging components and wiring components together as if directly into a panel. The fully assembled (and optionally tested) module can then be transferred from the assembly frame to the control panel frame. The reusable assembly frames simplify not only the module assembly process, but also the design and assembly of control panels, as the design and assembly may be performed in a modular manner. The assembly frame may be included as an element of an assembly station that provides portability and height adjustability.
In accordance with several embodiments described herein, components and wiring for one module of a control panel are designed for assembly in an assembly frame. The components, face plate, and wiring are then assembled into the assembly frame. The assembly frame may be mounted on a configurable assembly station such that the installation personnel may perform the assembly at their convenience, absent conflict with assembly of other modules of the control panel. The modularity of the design and the assembly frames enable multiple modules to be assembled in parallel or otherwise concurrently, eliminating physical constraints that have previously limited the number of personnel assembling a control panel.
Once the control module is assembled on the assembly frame, including the face plate, components, support features, DIN rails, terminal blocks, and wiring, the assembled module may be removed from the assembly frame and installed into the control panel frame. Multiple assembled control modules may be assembled in parallel at separate assembly frames and installed into the control panel frame to produce a control panel.
The assembly frame may include a faceplate frame moveably connected to side frames. The faceplate frame may accept a face plate that will become part of the control panel upon mounting to the control panel frame. The side frames may be connected to the faceplate frame using hinges to provide easier access to different portions of the assembly. The side frames may include mounting features for temporarily mounting DIN rails and other support features. With the faceplate and other components installed in the faceplate frame and the side frames, wiring among the components may be performed with the components in the assembly frame.
The assembly frame may be transported (e.g., as part of a movable assembly station) to the control panel frame on the adjustable workstation. The adjustable workstation may lift the assembly frame with the assembled module (and installed components thereof) to an appropriate level of the control panel frame. Once at the desired level, the assembled module may be removed from the assembly frame and installed into the control panel frame. For example, the faceplate with installed components may be removed from the assembly module and installed into the control panel frame. The support components, DIN rails, wiring, and other components temporarily installed into the assembly frame may also be installed into the control panel frame.
Modules installed into the control panel can be wired to other electrical power system hardware and/or connected at points of interface of the module (or otherwise wired together as appropriate) to accomplish an intended application (e.g., a set of functions pertaining to operation of an electrical power system) of an electrical system operator for which the control panel was designed, ordered, or otherwise requested or intended to be built.
In accordance with several embodiments described herein, components and wiring for one control module of a control panel are designed for assembly in an assembly frame. The components, face plate, and wiring are then assembled into the assembly frame. The assembly frame may be mounted on a configurable workstation such that the installation personnel may perform the assembly at their convenience. Once the control module is assembled on the assembly module, including the face plate, components, support features, DIN rails, terminal blocks, and wiring, the assembled control module may be removed from the assembly module and installed into the control panel frame. Multiple assembled control modules may be assembled in parallel in separate assembly frames and installed into the control panel frame to produce a control panel.
As can be seen, before assembly into a control panel frame, certain of the components of a module are free-standing and otherwise not interconnected or otherwise coupled together. Previously, assembly of components into a control panel required direct assembly (or installation) of these components into the control panel frame, which generally resulted in the deficiencies described above. Accordingly, the present disclosure provides assembly systems, methods, devices and techniques that enable assembly of discretely functioning and independently assembled (e.g., wired) and tested modules. As described in more detail herein, components of a discrete module may be temporarily installed and wired before intended installation into a control panel. Installation onto the control panel frame then involves simple removal of the face plate 202 and cross braces 214 and transfer and mounting of the face plate 202 and cross braces 214 into the control panel frame.
The systems, methods, devices, and techniques disclosed herein allow for modular design, assembly of multiple modules in parallel (including wiring), enhanced reproducibility, fewer personnel performing installation in a control panel frame during the same time period, easier upgradability of components, and more ergonomic installation conditions during assembly, and multiple other improvements.
A module can be related to one or multiple applications of a control panel. A control panel is intended to provide a solution to an application pertaining to operation of an electrical system. An application may be a collection of one or more functions that pertain to operation of an electrical system. Applications generally are related to main components of an electrical power system that need to be operated. Some examples of applications include but are not limited to:
The modules are defined 302 to be a self-contained or discrete solution that performs one or more electrical functions pertaining to operation of the electrical power system. In some embodiments, a module can perform a single function. In some embodiments, a module can perform multiple functions. The modules are defined 302 with a module definition that includes data specifying: components to perform the electrical function(s); a mechanical arrangement of the components to facilitate human interaction, use, and independent manufacture and testing of the module; electrical connections, including connections between the components and points of electrical interface with other modules and other equipment of the power system; and logical interactions, including logical connections between the components to perform the electrical function and logical interfaces with other modules or other equipment of the power system. Each module is designed and defined 302 to be discretely functional and independently wired, tested, and installed in a control panel.
Defining 302 module definitions allows for high predictability and repeatability of design and assembly at a modular level while affording customization and variability at the control panel level. Modules can be pre-manufactured and stocked in inventory or they can be more readily ordered and/or manufactured, thereby decreasing required lead time to ultimately install a control panel. As will be described more fully, rather than assembling all components of a control panel in a control panel frame, as has traditionally been done, defining modules can allow modules to be assembled independently, such as at different locations and/or at different points in time. A control panel comprising a plurality of modules can be assembled by assembling the plurality of modules in parallel with a plurality of workers (e.g., four workers) independently wiring each of the plurality of modules, thereby reducing assembly time. Further, defining 302 modules to assemble control panels can afford an ability to have repeatability in manufacturing or assembly of the modules, which can lower costs and defect rates. The assembly of a defined module can be a repeatable process that can be refined to remove errors and lower the defect rate (if not eliminate defects entirely). The repeatability of the process also opens opportunity for a workforce that has less experience and/or skill (at least lesser than may have been previously needed for, in effect, creating a custom panel every time).
The module definitions afford an ability to receive 304 input designating a set of modules to be included in a control panel to be assembled. The input may be received 304 from a customer, an operator, an engineer, or other requester. In some embodiments, the designation of a set of modules is received 304 at a computing system. For example, a selection interface may be presented on a computing device (e.g., a client computing device, a mobile smartphone, a tablet, a laptop) that provides a listing of modules from which the set of modules can be selected or otherwise designated. In some embodiments, the designation of the set of modules may be received over a communication network.
In some embodiments, the input received may be a listing of the modules in the set of modules. In some embodiments, the input may be a control panel definition that includes a designation of modules to be included in the control panel. In some embodiments, the input may be in the form of a control panel order. A customer, an operator, an engineer, or another requester can determine a control panel application (e.g., a collection of functions) to be used in operating an electrical system and accordingly order a control panel. The order or request for the control panel may be for a standard control panel product, a modification of a control panel product, or a custom-designed control panel. Regardless of the manner of requesting the control panel, an engineer or a computing system can generate a set of modules and a designation of that set of modules can be received 304.
A BoM can be prepared 306 or otherwise generated based on the designated modules. Module definitions that include data specifying components to be included in the module enable a BoM to be generated from a designation of a set of components. In some embodiments, a computing system can automatically prepare 306 or otherwise generate a BoM based on the designated modules and the definitions thereof. The BoM can include a listing of all components of every module of the designated set of modules. Stated differently, the BoM can specify a parts list that includes a part listing for each of the one or more components of all the modules in the set of modules designated. The BoM is to be used to order the components according to each part listing in the parts list.
The components according to the parts list of a BoM can be obtained 316, such as by ordering from a third-party or by initiating manufacture of the components. Having a parts list from a BoM at a point in time near to when a control panel (or application) is requested can drastically reduce lead time for assembling and installing a control panel. The components can be obtained 316 or otherwise sourced while continued engineering 308 of the forthcoming installation of the control panel is ongoing. In some embodiments, the obtaining 316 of components per the BoM can occur in parallel to, or otherwise concurrently with, ongoing engineering 308.
Once the components are obtained 316, the set of modules can be assembled 318. The modular design and module definition allows each module to be independently assembled 318. The modules are each assembled according to a corresponding module definition. The components are arranged according to a mechanical arrangement specified in the module definition. The components are wired or otherwise electrically connected and electrical interfaces are defined according to electrical connections specified in the module definition. Logical interactions, including logical connections between the components to perform the electrical function and logical interfaces with other modules or other equipment of the power system, are formed according to the module definition.
The modules can be loaded 320 with settings that provide customization of the functions of the modules, and thereby the application of the control panel. The settings can be loaded 320 by uploading a file to the module and/or components of the module. For example, in one embodiment a settings file may be uploaded to each component. In another embodiment, a settings file may include settings for multiple or for all components of a module. In still another embodiment, the module and/or components may be “connected” in that they are in communication with a communication network (e.g., the Internet) and settings can be loaded 320 to the components of the module via the network connection. The loaded 320 settings may further configure logical connections of the module according to a module definition and/or according to a configuration of the actual power system to be controlled by the control panel. Enabling configuration of the modules by loading settings enables a define module (e.g., a standard module) to be utilized in applications in operating a power system for a multitude of power system configurations.
Each module is designed and defined to be independently tested 322 to ensure proper operation. Testing may include testing to verify settings of each module. Testing may include current injection testing. The testing 322 can occur prior to installation in the control panel or following installation. Significantly, each module can be independently tested such that defects and/or errors are easily isolated to a module rather than being identifiable only as within the control panel, which can save significant time and expense in troubleshooting and finalizing a control panel for delivery and installation.
The modules are installed into a control panel rack to assemble 324 the control panel. The control panel assembly may be done prior to or after testing of the modules. Optionally, the control panel as a whole can be tested 326 for proper operation. As the modules are independently testable 322 and are designed and defined to operate independently and to present a defined interface to other modules and hardware of the electrical power system, testing 326 of the control panel as a whole may be a redundant and unnecessary action.
As mentioned, in certain embodiments, engineering 308 a forthcoming installation of a control panel occurs because a control panel is generally ordered or otherwise requested for a particular application pertaining to operation of an electrical power system at a particular location. Locations and applications are often unique, as previously explained, due to existing hardware and/or infrastructure, position on the grid, operator preferences and/or background or experience, and even factors such as climate and weather. Accordingly, additional engineering 308 and related services may be involved to eventually install and commission a control panel. Historically, lead times for installing and commissioning new control panels have been long, because each control panel was essentially built from scratch and the components for the control panel could not be identified until the engineering work was complete. The modules and modular assembly approaches and techniques described herein enable any additional engineering 308 to be done in parallel or otherwise concurrently with obtaining 316 components.
The engineering 308 of a forthcoming installation of a control panel, according to one embodiment of the present disclosure may include actions such as, but not limited to: obtaining module input data list(s), outage planning list(s), and commissioning plan and checklist(s); performing safety checks; conducting one or more site visits at the installation site; obtaining customer/requester drawings or renderings of one or more of: the installation site, an anticipated final rendering of the installation, and an interconnection of the control panel with other site hardware; developing an outage and commissioning plan; generating an engineering drawings package (e.g., using a design automation tool); transmitting the engineering drawings package(s) to the customer/requester; and obtaining approval of the engineering drawings from the customer/requester.
The engineering 308 of the forthcoming installation of the control panel may identify certain configuration adjustments or customizations to be made to components and/or modules of a control panel. The interconnection of the modules with other modules and with the power system apparatus may be unique or specific to a power system. Further customizations are done via settings that create logical connections internal to the IEDs that form the core of the module. A set of settings can be generated 310 that can be loaded 320 or otherwise applied to the components of assembled modules. The settings generated 310 may provide configuration of the components and/or the module, such as to select an option or setting made available by the component. For example, setpoints for functions associated with the forthcoming installation may be generated 310 and loaded 320 or otherwise applied to the components of assembled modules. As another example, logical connections for the component for functions associated with forthcoming installation may be generated 310 and loaded 320 or otherwise applied to the components of assembled modules. Nameplates and labels associated to the naming conventions used for the forthcoming installation may be generated 310 and loaded 320 or otherwise applied to the components of assembled modules.
The configurable settings of the components of the module allow customizing the module, and therefore the panel, to the requirements of the power system to be controlled. For example, there will be various teleprotection communications available and the module can be customized by programming to interface with what is available for this specific installation. The application may or may not require use of functions for manual and automatic control of power system breakers and switches and supervision of such functions (synchrocheck, dead voltage monitor, interlocking, etc). They may or may not require local and/or remote control and configuration to interface with various remote-control communications protocols. There are many variations that can be accommodated by engineering settings for the components (e.g., IEDs) that may form a core of the module. The generation 310 of settings may enable ongoing engineering 308 to occur in parallel or otherwise concurrently with the obtaining 316 of components and assembly 318 of the modules.
The control panel is installed 312 as ordered or according to any additional engineering. Once properly installed 312 at the location, the control panel can be put 314 into service or otherwise commissioned and made operational.
A producer of control panels receives many orders or requests for control panels with certain components or functionality. Data can be gleaned from these orders to identify 402 common components and/or functions of operating an electrical system. Modules can be designed and defined based on these common components and/or functions.
In defining a module, a set of one or more components is specified 404 that can perform an intended electrical function of the module. The specified 404 set of one or more components may include IEDs, circuit breakers, jumpers, terminal blocks, and other electronic components. The specified 404 set of one or more components may further include wiring, cross braces, DIN rails (or terminal block rails), brackets, and/or screws and other mounting and/or assembly hardware. The components specified 404 as belonging in a module definition may depend on a level of detail desired or appropriate for the module definition. For instance, in some embodiments, literally every part of the module (e.g., down to screws, washers, wire ties, powder coat, and the like) may be specified 404. In other embodiments, merely the electronic components are specified 404 in the module definition and mounting and assembly components may simply be on hand as part of the assembly process. Still other embodiments may include electronic components and some mounting components (e.g., cross braces and rails).
The set of components are to be organized or otherwise arranged in the control panel according to a specified 406 mechanical arrangement. In defining a module, the mechanical arrangement is determined and specified 406. The module is designed such that the components fit within a control panel rack of standard size or dimensions. The mechanical arrangement specifies positioning of the components so that the module fits within the space allotted within the control panel rack and its corresponding dimensions. Further, the electronic components may have space requirements, such as to allow airflow for cooling, to avoid arcing, and the like, and the mechanical arrangement is specified 406 to position the components to comply with these requirements.
Electrical connections of the module are also to be specified 408 in a module definition. The components are electrically interconnected, such as by wiring, pins, jumpers, and the like, to accomplish the function of the module. In defining a module, the electrical connections between the components and at interfaces of the module to connect with other modules and hardware of the electrical power system are determined and specified 408. The electrical connections may be specified 408 by an indication of which connector of a component is to be connected to which connector of another component and by what connection medium (e.g., a wire having given specifications). The electrical connections may be specified 408 to ensure that a connection medium is rated for the anticipated current and/or voltage of electricity to be passed therethrough.
Logical interactions of the module are to be specified 410 in a module definition. Not only are components of the module electrically connected, the meaning of the electrical signals can be determined to clarify the interconnection and interoperability of the components to accomplish the intended function of the module. In defining a module definition, the logical interactions, including connections between components and at logical interfaces with other modules or other equipment of the power system are determined and specified 410. The logical interactions may be specified according to an indication of a logical meaning of a signal on a connector of a component as provided over a connection medium to another connector of another component. The logical interactions may be specified 410 to ensure logical understanding within each module and at interfaces of the module to other modules and other equipment. The logical interactions may also be specified 410 so as to provide a meaningful mode to test that the module operates properly when assembled.
With the components identified 402 and specified 404 to perform an intended electrical function of a module, and with the mechanical arrangement specified 406, the electrical connections specified 408, and the logical interactions specified 410, a module definition can be created 412 or otherwise put into a useful and usable form. For example, the module definitions may be created 412 on a computing system and stored in a memory or other computer readable storage medium. The created 412 module definitions can then be utilized, such as by a computing system, an engineering team, an electrical power system operator, or the like, to present a designation of components for a module. Similarly, the created 412 module definitions can be utilized by a computing system, an engineering team, a third-party original equipment manufacturer (OEM), and/or a purchase and/or a manufacturing team to generate a BoM at or near the outset of a module being ordered or otherwise requested.
The assembly frame 502 includes a faceplate frame 504 and side frames 506. The faceplate frame 504 is to accept and support a faceplate of a module to orient a front of the faceplate forward (and optionally downward) and a back of the face plate rearward (and optionally upward) for ease of viewing and access by a user during assembly of a module. A face plate may be temporarily mounted on a forward side of the faceplate frame 504, in some embodiments, to be supported during assembly of a module. In other embodiments, a face plate may be mounted on a rearward side of the faceplate frame 504 for greater convenience and/or accessibility in temporarily mounting the faceplate to the faceplate frame 504. The faceplate frame 504 includes mounting features to which the faceplate of the of the module is to be temporarily mounted.
The side frames 506 each extend rearward from the faceplate frame 504 on opposing lateral sides of the faceplate frame 504. The side frames 506 are pivotably mounted, or otherwise moveably coupled, to the faceplate frame 504 to be rotatable between a narrow position and an open position. In
A first side frame 506 may be pivotably (or otherwise moveably) coupled to a first lateral side of the faceplate frame 504 and rotatable between a first (e.g., narrow) position that is in a plane substantially perpendicular to a plane of the faceplate frame 504 and a second (e.g., open) position, which is shown in
A second side frame 506 is coupled to the faceplate frame 504 at a second lateral side that is opposite the first lateral side of the faceplate frame 504 and the first side frame 506. The second side frame 506 also extends rearward from the faceplate frame 504 to provide accessibility to module components for the user during assembly of a module. The second side frame 506 may include mounting features for temporarily mounting a second cross brace to support components of the module during assembly of a module and after permanent mounting of the second cross brace during installation of the module into a control panel.
The assembly frame 502 may be installed on an adjustable workstation 510 with a horizontal work surface 512 and a lift 514 to adjust a height of the work surface 512. The assembly frame 502 may be pivotably mounted or otherwise moveably coupled to the work surface 512 such that a working angle of the assembly frame 502 may be adjusted between an upright position and a reclined position. The assembly frame 502 is shown in a reclined position in
The assembly frame 502 may be scaled to a dimension of a module of a control panel. The module may include components for performing a function or for a feature of the module. For example, a feeder protection module may include a feeder protection IED for mounting into the face plate, associated DIN rails, wiring, test switches, and the like. The feeder protection module may be assembled in the assembly frame 502 by installation (albeit temporary) of the face plate into the faceplate frame 504; installation of the feeder protection IED and associated test switches into the faceplate; installation of brackets onto the side frames 506; installation of the associated DIN rails, terminal blocks, circuit breakers, and the like onto the brackets; and the associated wiring of the various components as designed. Installation of the feeder protection module into a control panel frame may then be performed by transporting the feeder protection module that has been temporarily assembled into the assembly frame 502 to the control panel frame. The faceplate (that includes the feeder protection IED and test switches) and the brackets (including wiring) may then be removed from the assembly frame 502 and installed into the control panel frame.
A control panel order may be received at the control panel assembly computing system 1602. The control panel order may be received from an installation site 1606 or from the client computing device 1620 and may be received over the communication network 1625. In some embodiments, the client computing device 1620 can be co-located at the installation site 1606. The control panel order includes a designation of a set of modules to be included in a control panel to be assembled. Each module of the set of modules is selected from the plurality of modules defined. Alternatively, instead of a control panel order, simply a designation of the set of modules may be received.
To aid in designation of a set of modules, a module selection interface (e.g., a graphical user interface) may be presented to a user (e.g., technician, engineer, operator) on the client computing device 1620. The module selection interface may provide for selection at a modular level, such that the user selects modules for inclusion into a control panel. Generally such a selection process or option would be presented only to qualified users with knowledge about compatibility of modules and/or control panel definitions and the modules specified in such control panel definitions. Alternatively, a “wizard” or guided process may guide a user in selection of modules. The module selection interface and/or the control panel assembly computing system 1602 may present options for selecting modules according to compatibility constraints (e.g., rules or guidelines) directing which defined modules are compatible in a control panel. The compatibility constraints may be configured according to complementary functionality of modules, standard practices in the industry, best practices, and/or laws of electricity, physics, and/or other science. For example, the compatibility constraints may provide that a module for line protection should not be used for transformer protection, because standard industry practice is to avert combining control of separate major components of an electrical power system within a single control panel (e.g., because a repair of such control panel or component being controlled by such control panel would require taking two major components offline for the single repair). The compatibility constraints aid in removing module designation options (e.g., on the module selection interface) for modules that are not associated with an intended application or complementary to that application.
In another embodiment, the module selection interface may provide for selection of a control panel to be configured according to a customized application. The module selection interface may provide predetermined packages (e.g., similar to a template control panel) directed to certain applications (e.g., generic or common applications), and then provide options for customizing one or more components within such packages. For example, an application may be to monitor, control, and operate an additional switching device in the power system. Customization of a previously defined control panel via the selection interface can repurpose interface points, electrical connections and/or digital connections to achieve the desired functionality.
The customization is generally accommodated by selecting the modules. For example, if the application requires a certain type of local control interface, the correct control module that provides the required interface can be included in the control panel. There may be certain repurposing of wiring depending on the combination of modules selected. For example, if a breaker control module is required to provide breaker failure protection, outputs for breaker failure trip in a module get repurposed for breaker failure initiate. The module design such that complete repurposing of wiring to accommodate unanticipated variations is not required. Any customization of the system is accomplished by merely connecting external wires and in customizing settings.
In still another embodiment, the module selection interface may in fact provide for selection of stock control panels. A selection of a stock control panel corresponds to a designation of a set of modules that can be ordered either to build the requested control panel or to build a replacement of a control panel pulled from stock. Stated differently, the module selection interface may provide for selection of a control panel without any customization to the modules included therein.
The module definitions, as described above, afford an ability for the control panel assembly computing system 1602 to automatically generate or otherwise prepare a BoM for a designated set of modules. The BoM can be communicated to a computing system 1605 of the manufacturing facility 1604, for example over the communication network 1625. In some embodiments, the control panel assembly computing system 1602 can be co-located with the manufacturing facility 1604.
The manufacturing facility 1604 can immediately begin manufacturing of and/or a process of procuring components of the modules according to a parts list of the BoM. Additional engineering 1630a, 1630b by the producer of the panels and/or at the installation site 1606 can be ongoing while the manufacturing facility 1604 is producing/procuring components of the modules. The additional engineering 1630a, 1630b, according to some embodiments, may include any one or more of: obtaining module input data list(s), outage planning list(s), and commissioning plan and checklist(s); performing safety checks; conducting one or more site visits at the installation site 1606; obtaining customer/requester drawings (or renderings) of one or more of: the installation site, an anticipated final rendering of the installation, and an interconnection of the control panel with other site hardware; developing an outage and commissioning plan; generating an engineering drawings package, for example, using a design automation tool; transmitting the engineering drawings package(s) to the customer; and obtaining approval of the engineering drawings from the customer. As can be appreciated, the additional engineering involved may vary depending on whether the project is a greenfield (new) project or a brownfield (retrofit/upgrade) project.
The designated set of modules can be assembled at the manufacturing facility 1604 using assembly frames 1640 as described above, according to the module definitions. Assembling the designated set of modules on the assembly frames 1640 may include wiring according to a corresponding module definition and the data therein specifying electrical connections between the one or more components. Assembling the designated set of modules can include arranging the components according to the data specifying the mechanical interaction. Assembling the designated set of modules may include loading settings for components of the module.
The modules may be independently tested for proper functioning at the manufacturing facility 1604 or by an engineering person/team at the installation site. The independent testing of the modules can occur prior to or after assembly of the set of modules into a control panel.
With the modules assembled, the requested control panel can be assembled in a control panel rack 1642 at the manufacturing facility or a rack at the installation site 1606. The completed control panel is then installed or otherwise connected to electrical power system hardware and/or other equipment and then put into commission. Installing the control panel can include one or more of: mobilizing for construction; verifying and performing a safety plan; implementing an isolation plan (switching orders); implementing a demolition plan (including panel cuts); installing and wiring the control panel to one or more of adjacent hardware and the electrical system (using checklists); performing functional tests on the control panel; putting an associated zone of the electrical power system into service per switching orders; and updating the engineering drawings package to reflect changes made during installation to produce a final engineering drawings package that documents the control panel as-installed. As can be appreciated, the installation process may vary depending on whether the project is a greenfield (new) project or a brownfield (retrofit/upgrade) project.
