a. Field of Invention
The present invention relates to electrical power supply, and more particularly to a system for conserving electrical energy consumption in commercial, industrial, residential, or other energy consumption settings. The present invention system conserves electrical energy consumption with control devices at or near incoming power breakers to increase efficiency relating to loads, distortions, spikes and/or power factors, as well as other deviant characteristics. In addition, this present invention system with a three component iterative transformer that includes three cores and three interconnected windings, improves response time and results in more energy savings than the prior art electric power supply energy saving systems, including those previously developed by the present inventor.
In a typical electrical power consumption setting, electricity is transmitted via power lines or transmission lines to a facility, such as a factory, office, home, etc. The main electrical line is typically connected to a power meter, which in turn is connected to a main breaker box of the facility via a main line. Electricity is distributed to various loads of the facility through various individual circuit breakers in the main breaker box.
In general, and particularly in industrial settings, electrical loads, such as non-linear loads, including DC motors, create harmonic distortions, electrical spikes, and poor power factor, which have negative impact on efficiency and the condition of the load itself (e.g., overheating and reduced motor life). Other internal and external physical conditions also contribute to these and other deviant (inefficient) characteristics that adversely affect electrical consumption. Thus, the present invention is a system for reducing electrical consumption that includes one or more devices that recognize electromagnetic interference with means to suppress line transient voltage surges, means to regulate harmonics distortion, means to enhance power factor correction and means to maintain phase regulation by maintaining phase relationship between voltage and current at times of increased power demands, using newly discovered arrangements of components to achieve these results.

In order to maximize the performance of the symmetrical power system, the isolation transformer has a bifilar-wound secondary winding.

The center tapped is connected to the output power load circuit as a ground reference potential with respect to the symmetrical ac output so as to constitute the reference ground potential for the power supply and load. Since symmetrical ac power is applied to the load by the system, reactive load currents, other power artifacts, EMI and RFI emissions and other interference ad noise components ordinarily resulting from the application of conventional ac power to the load are reduced or eliminated by appearing as equal inversely phased signal elements which cancel one another. In order to maximize the performance of the symmetrical power system, the isolation transformer has a bifilar-wound secondary winding.
U.S. Pat. No. 6,009,004 discloses a new single-phase passive harmonic filter for one or more nonlinear loads. The filter improves the total system performance by drastically reducing the line side current harmonics generated by non-linear loads. The filter includes two inductive portions across one of which is connected a tuning capacitor. The parallel combination of one inductive portion which the tuning capacitor forms a series tuned filter configuration while the second inductive portion is used for harmonic attenuation. A shunt capacitor is employed for shunting higher order harmonic components. A single-phase passive voltage regulator provides the needed voltage bucking to prevent over voltage at the load terminals of the filter. The filter provides an alternate path for the harmonic current generated by non-linear loads. The over voltage caused by the increased capacitive reactance is controlled by either capacitor switching or by the use of the passive voltage regulator or a combination of the two. Capacitor switching is dependent upon load conditions.
U.S. Pat. No. 6,014,017 describes a method and an apparatus for power factor correction for a non-ideal load, which is supplied for a main power supply, by a compensation device which is electrically connected in parallel with the load and has a pulse converter with at least one capacitive store. A transfer function space vector is calculated as a function of a determined mains power supply voltage space vector, a mains power supply current space vector, a compensator current space vector and of an intermediate circuit voltage which is present on the capacitive store. As a result of which the pulse converter generates a compensator voltage space vector on the main power supply side as a function of the intermediate circuit voltage. A compensator current space vector, that keeps the undesirable reactive current elements away from the mains power supply, is thus obtained via a coupling filter that is represented as a compensator inductance.

In the drawings:
Overview
In one preferred embodiment, the present invention is a system that is in line with AC Incoming Voltage to an electrical load site, such as an industrial, commercial, educational or recreational facility. A typical electrical supply arrangement includes an electrical feed line from the service provider connected to all of the electrical devices in a particular location, as in the case of circuit breakers for the main source or for fuel cells or generators for large motors.
In one implementation, the system is attached at the main source for such things as large motors and motor driven systems. It is connected in a manner that reduces the harmonics in a building; lowering the total harmonic distortion (ThD) to a very low value and adjusting any low Power Factor so as to be adjusted to 0.95 or greater. Included is a Transient Voltage Surge Suppressor (TVSS) with a feature to reduce the spikes that can be portable, mobile, or hard wired, for the protection of the location.
With this in mind, the present invention system can reduce the demand for power by controlling the noise factor and regulating electrical surges and sags in a building, thereby lowering the energy consumption. The present invention system also has the ability to work with large generators and with fuel cell systems for preventing a loss of voltage and current in a given situation and maintaining power requirements needed for short periods of time. In the generator, the system not only reduces kilowatt usage being drawn but also reduces its need for fuel consumption. In the fuel cell, the system is able to suppress the surge/sag, which results in more efficiency for the fuel cell to produce more energy.
In one implementation, a parallel AC power system helps provide a balanced AC load to the potential electrical feed to the building or power supplied by the utility company by means of an electrical enclosure with its electrical parts. It is installed parallel to the main load and/or to the motors drawing the most power. It acts as a voltage and current absorber and corrects a poor power factor. It also improves the THD (Total Harmonic Distortion).
When this present invention system is connected in parallel to the source, it decreases the phase angle of current and voltage. If voltage or current are out of phase it adjusts to proper phase. This system reduces power consumption and responds to the load by means of its current draw and adjusts to the demand by lowering its storage mechanisms. It adjusts the voltage to its current demands by giving the device a supply of voltage, which results in lower demand on usage of its power consumption.
Principles of the present application are particularly applicable to industrial settings with high current demands (e.g., with loads drawing up to 5,000 Amps). It should be recognized, however, that principles of the present invention are applicable to other electrical load settings, from the largest industrial and commercial applications to small residential and ancillary building electrifications.
Generally, the arrangement of
Capacitors C1, C2, C3, C12, C13, C14 (which are a dry film type according to one preferred present invention embodiment implementation) are connected in parallel to the front end of the unit. This helps in the reduction of the lower harmonic noise on the fundamental frequency (e.g., 30 Hz to 400 Hz) input lines. This type of arcing band pass filter, (filter capacitors) are intolerant of reverse current and heat. Run type capacitor working voltage [WV] ratings should be treated with respect. The WV rating is virtually the maximum voltage rating. Despite their more delicate nature, these filter capacitors offer substantial advantages over electrolytic filter capacitors. The main advantages are more joules of energy storage per capacitor, reduced weight and reduced volume. This combination with the dry caps is called an “Arcing Setup” in a circuit with the installed MOVs. When the capacitors are operated in series, they should share the voltage equally. In order to do this, a voltage equalizer resistor is connected across each capacitor. The equalizer resistor comes with the caps on them or in them. In
Capacitors C5, C6, C7, C8 (which are oil type capacitors for high current applications according to an embodiment of the present invention) are connected in series to allow for more current to pass; in addition the needed values will be half the capacitance but will allow for more current to pass through them and prevent damage to the capacitors in this manner from the harmonic noise still passing through them. The MOVs (metal oxide varistors) VAR1, VAR2, VAR3, VAR4, VAR5, VAR6 are for the transients spikes from the input line and also reduce the transponder non-fundamental frequencies for the AC line suppression for creating a very clean EMI/RFI reduction from the power lines.
Arranging three component chokes LA1, LA2, LA3 in series on the Hot legs (Red, Blue, Black and Green) creates a low pass filter or other non-fundamental frequency currents flowing to the load but opposite in phase; filter for as setting up a current load to the source for balancing of the phases being applied to capacitors C9, C10, C11 (which are oil type capacitors according to an embodiment of the present invention). This large LC type network creates a network where the current being drawn by the incoming load reacts with the power factor; this will create an imbalance load in the case of offset lagging current and creating a current generating means in which the excess power is then converted to power from the fundamental frequency then supplied back to the AC power source, which may include a generator or fuel cell.
With MOVs VAR7, VAR8, VAR9, VAR10, VAR11, VAR12 across the leading current, the MOV's now can reduce the major part of the voltage transients whereas the current now will be reduced at the source. Capacitors C15, C16, C17 (which are oil type capacitors for high current according to an embodiment of the present invention) are provided in the circuit for added protection of the stray harmonics that could damage the upcoming capacitance stage, whereas this will keep the capacitors from having more current through them to prevent an unwanted catastrophic failure. The output stage with one or more capacitors is acting as a Voltage/Current storage device; wired as a “Y” or delta configuration sets up a Kvar injection to the incoming source for proper balancing of all voltage and current fields across the current power source. The resistors R4, R5, R6 in conjunction with a lamp, displays an indication for that phase which is active.
Paralleling up to 12 of these device stages together across the 3 phases and injection of 1000 to 50000 Kvar's to the power source with great response with less noise created by the motors, resistive loads and the inductive loads; this nonlinear loading represented by non-fundamental frequency load currents in the source; the demand with harmonics on a given location creating a larger bill to the customer and not really using that demand. This will bring the demand down on a building with the reduction of harmonics, thereby stabilizing the building with cleaner AC power in the building.
The first stage of the system illustrated in
Significantly, this system lowers the harmonics being produced by the motor (in the case in which the load is a motor), thereby greatly reducing the current being consumed. As an additional benefit, this keeps the motor running cooler, hence reducing the wear and tear on the motor. Furthermore, there is achieved a reduction of energy being used by means of Kw (kilowatt hours) through lowering the demand from its source. Energy savings will occur with all of these key features working together; the result being a significant (e.g., 10 to 30%) reduction of energy used by the consumer and less maintenance on motors with a cleaner energy going back to the utility company supplying the power.
Three Component Choke Design
According to an embodiment of the present invention, three component (i.e., three core) chokes LA1, LA2, and LA3 are configured using a coil design as described herein below. Generally, a coil design according to this embodiment of the present invention employs a generating means of detecting the current in the paralleling noise reduction unit to the incoming power source. In one implementation, each coil is situated in an upright position and is constructed with the following components for its makeup: three magnetic coil cores (which may be circular, rectangular, or otherwise, and which may be a single piece or an arrangement of pieces with or without spacing to create a coil loop (core)), e.g., sets of rectangular half coil pairs (a coil is established when the two split half rectangles are positioned with opposing ends facing each other). The wire is being used may preferably be a “THWN” gas and oil type wire.
The direction of the wire from the white (Neutral) is wound in a proper manner for the magnet flux fields and have this conformingly to the windings. The Hot legs using a color such as (Black, Red, Blue) also follow this winding pattern for proper operation. This has the most effect on the loads being applied to for the direction of the currents being picked up from the source. The reaction of the white (Neutral) plays a role in where this reduces the amount of frequencies where as it puts the phasing at 180 degrees out of phase to the incoming hot leg. The means of winding the hot also places a 90 degree phase from the white, and thus counteracts the flow of current and the harmonic frequencies out of phase to the coil reactor in the circuit. This sets up the current sensing device for the voltage and the current sensing whereas it removes the fundamental frequency component acting in a manner as a notch filter device to the applied circuit; its power efficiently flows in either direction between its output storage capacitors in the circuit. Like a notch filter, this removes the fundamental frequencies and controls the current source by injecting a current back into the AC power line from the storage capacitors connected in a manner like a “Y” or Delta stage in the unit. This method can be called as a reactor or a means of controlling the harmonics in a given power source for means of saving energy and the reduction of harmonics that reduces the capacitors life a great deal in a circuit. This also can be used as a current detection method in which it can replace a “CT” clamp used to detect the current in a given circuit without clamping it to the incoming line.

Relevant/Related Concepts
The following discussion is provided to further elaborate on concepts relevant to various aspects of the present invention.
Positive sequence harmonics—such harmonics try to make a motor run faster than the fundamental. Negative sequence harmonics—such harmonics try to make the motor run slower than the fundamental. In both cases the motor loses torque and heats up. Changing power supplies can affect or disrupt normal harmonics. Abnormal harmonics can also cause transformers and motors to overheat. Even harmonics problems will disappear if waveforms are symmetrical, i.e., as equally positive and negative. Zero sequence current harmonics add in Neutral conductors. This can cause these conductors to also overheat.
Current distortion is expected in a system with non-linear loads like DC power supplies. In a typical case, when the current distortion starts to cause voltage distortion (THD) of more than 5%, this signals a potential problem.
K-factor indicates the amount of harmonic currents and can help in selecting transformers. K-factor may be considered along with apparent power (kVA) to select a replacement transformer to handle non-linear, harmonics-rich loads. K-factor is a mathematically derived value that takes into account the effects of harmonics on transformer loading and losses. Voltage and frequency should be close to the applicable nominal values: 120 V, 230 V, 480 V; 60 Hz, or 50 Hz, although 40 Hz to 400 Hz frequency range conditions may experience significant improvements with the present invention systems. For example: Checking the voltages and currents to see if the power applied to a three phase induction motor is in balance. Each of the phase voltages should not differ more than 1% from the average of the three. Current unbalance should not typically exceed 10%. Voltage unbalance causes high unbalanced currents in stator windings, resulting in overheating and reduced motor life. If unbalance is too high, other correction modes may be used to further adjust with the use of the heretofore described present invention system in the power system.
Typically, crest factor close to 2.0 indicates high distortion. A pure sine wave would have a crest factor of 1.414. Anything higher is a result of distortion in the lines and feeding also back to the incoming power source this is also maintained with the EBU system installed.
Dips (sags) and swells may indicate a weak power distribution system. In a weak system, voltage will change considerably when a big motor or a welding machine is switched on or off. This may cause lights to flicker or even show visible dimming. It can also cause reset and data loss in computer systems and process controllers. By monitoring the voltage and current trend at the power service entrance, it is possible to determine if the cause of the voltage dip is inside or outside the building. The cause is inside the building (downstream) when voltage drops while current rises; it is outside (upstream) when both voltage and current drop. The final storage of the present invention corrects this problem.
Transients in a power distribution system can cause many types of equipment to malfunction. Equipment subjected to repeated transients can eventually fail Events occur intermittently, making it desirable to monitor the system for a period of time to locate them. Voltage transients can be monitored when electronic power supplies are flailing repeatedly or if computers reset spontaneously. To isolate the fault location, it is possible to use the transients function and monitor at several points in the distribution. Working down the line, circuits can be eliminated that don't show events where as further monitoring should be initiated for circuits that show the event in sharper detail. The sharper the event, the closer to identify the load causing the problem and as the unit monitoring will also isolate this allowing determination if it is a single, dual or three phase load causing the problem, further reducing the number of culprits in the building.
The voltages and currents in the Unbalance table can be used to check if applied power is in balance; for example, on a three phase induction motor. Voltage unbalance causes high unbalanced currents in stator windings, resulting in overheating and reduced motor life. Each of the phase voltages should not differ more than 1% from the average of the three. Current unbalance should not exceed 10%. If unbalance is too high, the use of the present invention will act as a stabilizer to the power system. Each phase voltage or current can be split into three components: positive sequence, negative sequence, and zero sequence. The positive sequence is the normal component present in balanced 3-phase systems. The negative sequence results from unbalanced phase-to-phase currents and voltages. For instance, this component causes a ‘braking’ effect in three phase motors, resulting in overheating and life reduction. Zero sequence may appear in an unbalanced load in 4 wire power systems and represents the current in the N (Neutral) wire. Unbalance exceeding 2% is considered too high Inrush is the large spike most commonly caused by a motor load coming on-line. As it first energizes, the motor utilizes a higher amount of current than when runs at a constant speed. This large current draw frequently causes a large enough voltage dip to send other equipment off-line or cause the lights to blink. The inrush is capped with the present invention and allows the inrush magnitude along with the length of time it takes the motor to come up to speed. If the inrush exceeds the breaker setting, it nominally will trip but the present invention will stabilize the problem and the storage in the device will hold the power for a much longer time for the correction of this problem.
The present invention, as indicated above, uses unique grounding (Green line ground at the iterative transformers), in addition to other unique features and component arrangements, to achieve unexpectedly favorable performance results. When these grounds are arranged in the foregoing manner, additional energy savings is realized. That is, the reduction of energy consumption is enhanced. Thus, failure to ground the transformers as indicated may adversely affect the system's ability to maximize reduction in energy consumption. The combinations of the third coil core and windings, the changes in the capacitor arrangements with dedicated resistors and the unique groundings are surprisingly synergistic and increase response speed and efficiencies of the system, including active filtering.
