The present invention generally relates to a multiphase voltage regulation and control in a multiphase power system having a single phase control; and a system, method and apparatus for multiphase voltage regulation and control having a single phase control.

The main form of distribution of alternating current (AC) power distribution systems. AC power distribution is typically delivered as single phase power or multiphase power. A multiphase system carries two or more alternating currents, each of which has one phase offset from the other phase. This allows the multiphase system to transmit more power than a single phase power system. A typical example of a multiphase system is a three phase power system. In a multiphase system, a voltage regulator controller is used to maintain local operational control of a plurality of connected single phase mechanisms that make up the multiphase system. Existing multiphase control systems are typically limited to operating one of the single phase mechanisms in the multiphase system. A multiphase control system capable of controlling multiple mechanisms with single phase control typically depends on a plurality of processing units having each of the plurality of mechanisms and phases.

Additionally, in multi-phase systems, one or both of the phases may temporarily become non-energized due to a failure or periodic interruption (typically related to maintenance). When a phase is de-energized, the corresponding current can be out of phase when the non-energized phase is re-energized. This can cause the multiphase system to become balance. The present invention provides a solution for remedying the shortcomings of existing multiphase control.

The following description of the exemplary embodiments refers to the accompanying drawings.

Now turn to the schema (where the same component symbol indicates all the same components), a detailed description of this An exemplary embodiment of the invention.

Turning to Figures 1 and 2, a voltage regulator controller 100 in accordance with an exemplary embodiment of the present invention is described. FIG. 1 illustrates an exemplary block diagram of one of the voltage regulator controllers 100, and FIG. 2 illustrates an example of a front panel of the voltage regulator controller 100. As shown, the voltage regulator controller 100 includes a main control module 102, a line module 104, and an additional line module 106. The main control module 102 and the line module 104 include a voltage regulator to automatically or manually adjust one of the phases of a multiphase power delivery system. The voltage regulator controller 100 uses a phase-crossing tap changer 150 to regulate the voltage across the phase. In some exemplary embodiments, the main control module 102 and the line module 104 can adjust the out-of-phase such that it maintains an almost constant 120 volt AC rating based on the configuration of the voltage regulator controller 100. Stage output line voltage. It should be noted that the voltage regulator controller 100 can adjust the voltage that is out of phase to a voltage range other than 120 volts AC. As understood in the art, the out-of-phase tap changer 150 includes a multi-tap transformer or autotransformer. In other words, as understood in this technique, the out-of-phase tap changer 150 includes mechanical and electrical components to select one of a number of tap positions to adjust the voltage across the phase. When the tap changer 150 changes the tap position, one of the line voltages that are out of phase is correspondingly increased or decreased.

In some exemplary embodiments, main control module 102 includes a processor that automatically controls the operation of the out-of-phase tap changer 150, a display 204 that monitors conditions, and a local keypad 202. It is used to interface with the processor; and other indicators 206 that indicate the status of the main control module 102 and the line module 104. In some exemplary embodiments, main control module 102 includes a user interface that includes an output portion and an input portion in addition to a combination of display 204 and a keypad 202. In addition, the line module 104 includes: a plurality of switches 212, 214, and 216 for manually controlling the operation of the out-of-phase tap changer 150; and connection terminals 218 and 219 for supplying power Go to the tap changer (if needed) and check each of the voltages out of phase.

To adjust the voltages that are out of phase, the main control module 102 and the linework module 104 provide control signals 111 to the out-of-phase tap changer 150. The control signal 111 can be provided manually (i.e., by a lineman) or automatically (i.e., by a processor) depending on the mode of operation of the voltage regulator controller 100. In particular, in certain exemplary embodiments, an automatic/manual or mode switch 212 can be used to configure the voltage regulator controller 100 to be in phase (automatic/automatic) or manual (local) voltage. Adjustment, as shown in the figure. In general, the operation of the tap changer 150 can be manually controlled by a lineman or field technician using the linework module 104, and the main control module 102 is configured to automatically control the operation of the tap changer 150. Switch 212 also includes a cut-off position. When the switch 212 is in the cut-off position, the voltage regulator controller 100 cannot automatically or manually adjust the voltage across the phase.

When the switch 212 is set to the automatic mode, the processor of the main control module 102 relies on the voltage and current sense signal 112 from the phase to determine whether the out-of-phase tap changer 150 should be controlled to a new tap position. . That is, in certain exemplary embodiments, based on the voltage and current sense signal 112, the processor can determine that the voltage across the phase is out of limits (ie, too high or too low) (refer to one of the desired phase voltages) And, the tap changer 150 is controlled to use the control signal 111 to achieve a corresponding and appropriate tap change. For example, control signal 111 can deliver the power required to drive a motor that is one of the tap changer 150. Under the supervision and control of the processor of the main control module 102, the electronically controlled switch of the voltage regulator controller 100 and/or other associated circuits can be used to electronically turn the drive over-the-counter tap changer on or off. The power required by the 150 motor. For example, a TRIAC, relay, or integrated gate bipolar transistor (IGBT) and other devices can be used to electronically turn the power required to drive the motor of the out-of-phase tap changer 150. Using an electronically controlled switch, the main control module 102 can tolerate current supply to the motor of the out-of-phase tap changer 150 when a tap change is required. When the control signal 111 is provided, the voltage regulator controller 100 can rely on the sense signal 113 from the out-of-phase tap changer 150 to determine when a tap position change is complete.

When the switch 212 is set to the manual mode, the lineman can rely on the voltage from the phase and The current sense signal 112 determines if the out-of-phase tap changer 150 should be controlled to a new tap position. That is, the line readable display 204 and/or indicator 206 (which is updated by the processor of the main control module 102 based on the voltage and current sense signal 112) to determine if the over-the-counter tap changer should be 150 controls to a new tap position. Alternatively or additionally, the lineman can also use the voltage connection terminal 219 to manually check the voltage across the phase. In certain exemplary embodiments, the lineman can control the out-of-phase tap changer 150 to a new tap position by using the up/down tap changer 214. When the up/down switch 214 is used, the control signal 111 delivers the power required to drive the motor of the out-of-phase tap changer 150 to a new tap position. It should be noted that in the manual mode of operation, the up/down switch 214 manually controls the electronically controlled switch of the voltage regulator controller 100. In particular, when the automatic/manual switch 212 is set to the manual mode, the electronically controlled switch manually supplies power to the off-phase based on the up/down switch 214 and not based on the automatic control signal from the processor of the main control module 102. The motor of the tap changer 150. Using the internal/external power switch 216, the lineman can select the power internally supplied to drive the motor of the out-of-phase tap changer 150 (i.e., the line voltage from the phase itself) or from an external source via the external source terminal 218. The power for driving the motor of the out-of-phase tap changer 150 is supplied.

The additional lineman module 106 includes circuitry needed to control the additional phase of voltage regulation for both the automatic mode of operation and the manual mode of operation. In an exemplary embodiment, and as described herein, the additional lineman module 106 is configured to adjust the two additional phases using the additional phase tap changer 160. However, in certain other exemplary embodiments, two or more of the following phases may be adjusted by one of the extensions of the circuitry of the additional lineman module 106. The additional lineman module 106 includes an electronically controlled switch (such as a TRIAC, relay or IGBT) and other associated circuitry required to control the additional phase tap changer 160. In addition, the add-on line module 106 includes circuitry for receiving the sensed signal 116 from the add-on phase tap changer 160 and relaying the signals to the control module 102 as a sense feedback signal 118 for two Each tap changer of the additional phase tap changer 160.

Automatic control of the additional phase tap changer 160 is accomplished by the main control module 102 via the add-on linework module 106. Based on the voltage and current sense signal 114 received from the additional phase, the main control module 102 passes the automatic control signal 117 to the additional linework module 106 to adjust the line voltage of the additional phase. That is, when the switches 222 and 232 of the additional line module 106 are set to the automatic mode (automatic/remote position), the automatic control signal 117 from the main control module 102 is used as a switch for the additional line module 106. Control signals for the electronically controlled switches and other associated circuits to control the additional phase tap changer 160. Next, the power for changing the tap position (via control signal 115) is provided to the motor of the additional phase tap changer 160. When the tap position of the add-on tap changer 160 is changed, the add-on module 106 receives the sense signal 116 and relays the signals to the control module 102 as the sense feedback signal 118. Thus, the main control module 102 can determine when the additional phase tap changer 160 has completed the tap change operation.

With regard to manual control of the first additional phase and the second additional phase, the add-on line module 106 includes a first section 220 that includes switches 222, 224 for manually controlling the first additional phase tap changer 160. And a second section 230 comprising switches 232, 234 and 236 for manually controlling the second additional phase tap changer 160.

Regarding the first section 220, the auto/manual switch 222 determines whether the first additional phase is manually voltage regulated by the lineman using the up/down switch 224 or is automatically voltage regulated by the main controller 102 via the automatic control signal 117. In certain exemplary embodiments, when the switch 222 is set to the manual mode, the lineman can use the raise/lower switch 224 to control the first additional phase tap changer 160 to a new tap position. That is, when the switch 222 is set to the manual mode, the control signal 115 delivers the power required to drive the motor of the first additional phase tap changer 160 to a new tap position based on the position of the up/down switch 224. It should also be noted that in the manual mode of operation, the up/down switch 224 is relied upon to control the electronically controlled switch of the add-on line module 106 to deliver power to the motor of the first additional phase tap changer 160. Using internal/external power switch 226, the lineman can select an internal supply for driving the first additional phase tap The power of the motor of the head changer 160 (i.e., the line voltage from the first additional phase itself) or the motor for driving the first additional phase tap changer 160 is supplied from an external source via the external source terminal 218. electric power.

The second section 230 operates similarly to the first section 220, but is regulated relative to the voltage of the second additional phase. That is, the second section 230 includes circuitry for both automatic voltage regulation and manual voltage regulation of the second additional phase. Additionally, the second additional phase tap changer 160 can be manually controlled by a lineman using the switches 232, 234, and 236 of the second section 230.

It should be noted that based on the separation of the control, sensing, feedback and driving circuits in the main control module 102 and the line module 104 and the additional line module 106, when the additional line module 106 is used, the main control module The voltage regulation of the two additional phases by the 102 and the linework module 104 does not contribute to significant additional costs. Therefore, the main control module 102 and the line module 104 can be manufactured and sold according to the voltage adjustment option of the additional phase without significant increase in cost, and can be purchased separately if automatic and manual voltage adjustment of the additional phase is desired. Additional lineman module. It should be further noted that the total cost of automatic and manual control of the three phases for the main control module 102, the line module 104 and the additional line module 106 for automatic and manual control of three phases can be significantly lower than three. The individual master control module 102 and the linework module 104 are directed to the total cost of automatic and manual control of three identical phases.

Turning to FIG. 3, one aspect of the operation of voltage controller 100 is described in further detail with reference to an exemplary schematic diagram of certain elements of voltage regulator controller 100. As mentioned above, the power supplied to one of the motors of a tap changer can be provided by the line voltage of the phase regulated by the tap changer. Referring to FIG. 3, the "Ph A Vout" reference term indicates the line voltage that is out of phase, which is the voltage regulated by the main controller 102. Power from the out of phase passes through switch 216 (which is set to internal power) and passes through the switch contacts of relay 310 before being provided to TRIAC 350. Consistent with the description provided above, the TRIAC 350 is operative to electronically turn the power of the motor of the out-of-phase tap changer 150 in response to a control signal provided by the processor of the main control module 102. Similarly, by the second additional phase line voltage "Ph C Vout" provides power to the TRIAC 370. It should be noted that TRIACs 350, 360, and 370 can include any electronically controlled switch, as described above.

If the line voltage "Ph B Vout" of the first additional phase is powered off or dropped to zero (or close to zero) due to system failure, repair disconnection or any other reason, the processor of the main control module 102 passes The voltage and current sense signals 114 detect a drop in the line voltage. In this condition, the first additional phase tap changer 160 is generally not controllable to change the tap position, since the motor of the first additional phase tap changer 160 is powered because power is not available from the first additional phase. . If the power deficiency persists for an extended period of time and the phase and the second additional phase are still voltage regulated, the tap position of the phase and the second additional phase may drift to a position away from the last position of the first additional phase. When the line voltage of the first additional phase recovers, the multiphase power delivery system will be particularly unbalanced because the phase and the second additional phase have been adjusted to a different tap position than the first additional phase. This condition is undesirable and can result in system damage.

Therefore, to address this condition, when the processor of the main control module 102 detects a drop in the line voltage of the first additional phase, it is configured to automatically activate the relay coil 314 via the "PhB Ext Ena" signal. The contacts of the relay 320 are switched. In this case, it should be noted that the internal/external power switch 226 is bypassed and the line voltage of the power from the phase "Ph A Vout" is supplied to the TRIAC 360 through the coupling 390. In particular, the coupling 390 provides a circuit path between the phase line voltage "Ph A Vout" and the TRIAC 360, and optionally supplies power to the first additional phase tap changer 160 to change the tap position. . Similarly, if the line voltage of the phase or second additional phase drops to zero, the processor of the main control module can automatically switch the contacts of the relay 310 or 330 by energizing the relay coils 312 and 316, respectively. For example, in some embodiments, if the line voltage of the second additional phase drops to zero, the line voltage from the first additional phase can be provided to the second additional tap changer 160. In some exemplary embodiments, when one of the phase line voltages is de-energized, the line voltage of any one of the remaining energized phases may be supplied to the tap changer of the power down phase.

As a safety measure, one of the magnetic poles of each of the internal/external switches 216, 226, and 236 is coupled to the control switches 313, 315, and 317, respectively. However, control switches 313, 315, and 317 are optional and may be omitted in alternative embodiments. As shown in FIG. 3, the control switches 313, 315, and 317 are connected or disconnected to a 24 volt DC power supply based on the "PhA Ext Ena" and "PhB" from the processor of the main control module 102. The Ext Ena" and "PhC Ext Ena" control signals energize the relay coils 312, 314, and 316, respectively. Therefore, if the lineman switches the internal/external switch 226 to the cut or external position (ie, any position other than the internal position), the 24 volt DC power supply is disconnected from the relay coil 314 and the relay coil 314 cannot be made. Power on (regardless of the "PhB Ext Ena" control signal from the processor). The line voltage "Ph A Vout" is automatically connected to the TRIAC 360 from the phase when the internal/external switch 226 of the first section 220 of the add-on line module 106 is set to any position other than the internal power. As illustrated in Figure 3, internal/external switches 216 and 236 are similarly connected to prevent line voltage from being automatically connected between phases when the internal/external switch is switched to external power.

Turning to Figure 4, one embodiment of a method 400 for automatically powering a power down phase is described. In step 410, the processor of the main control module 102 detects a decrease in one of the line voltages of the first phase of one of the multiphase power systems. For example, referring to FIG. 1, the processor of the main control module 102 can detect that the first additional phase has been powered down based on the voltage sensing signal 114. In this condition, the processor recognizes that the first additional phase is unable to supply the power required to change the tap position using the first additional phase tap changer 160. In other words, the tap position of the first additional phase tap changer 160 cannot be updated by the processor of the main control module 102 in the automatic mode, because the line output of the first additional phase cannot be obtained for the first The power supplied by the motor of an additional phase tap changer 160. As mentioned above, this condition is undesirable, especially when the phase and the second additional phase are regulated by voltage to a tap position away from the tap position of the first additional phase. It should be noted that although the line voltage of the first additional phase has decreased, the main controller 102 may seek to adjust the tap position of the first additional phase to be similar or identical (eg For example, one of the position of the tap position of one of the phase and the second additional phase. If the tap position of the first additional phase is adjusted to a position similar or identical to one of the out-of-phase and one of the tap positions of the second additional phase, when the first additional phase is re-energized and the line of the first additional phase When the voltage is restored, the system will be more likely to maintain balance.

Therefore, after the processor of the main control module 102 detects that the line voltage of the first additional phase has decreased based on the voltage sensing signal 114, the method proceeds to step 420, where it is detected whether the internal is selected for the first additional phase. Or external power. For example, internal/external power switch 226 can be used to detect whether internal or external power is selected for the first additional phase. In some example embodiments, if internal power is detected, the program proceeds to step 430 where a second phase of the multiphase power system is coupled based on a control signal from one of the processors of the main control module 102. One of the circuit paths between the first phases. As depicted in FIG. 3 and as discussed above, the processor can provide a control signal "Ph B Ext En" to energize the relay coil 314, thereby bypassing the internal/external power switch 226 using the switch contacts of the relay 320. And coupling the circuit path 390 between the phase of the multiphase power system and the first additional phase. After power is coupled between the out-of-phase and first additional phases via circuit path 390, power is supplied to the TRIAC 360 of the first additional phase.

After power is provided to the TRIAC 360, in step 440, the processor of the main controller 102 can control the first additional phase tap changer 106 as appropriate. For example, the processor of the main controller 102 can control the tap position of the first additional phase tap changer 160 to have one of the tap positions based on one of the cross-over or second additional phase tap positions. When power is more coupled to the first additional phase, the process returns to step 410 to determine if the first additional phase is still powered down. If not, the processor decouples any circuit path (such as path 390) between the second phase (ie, the phase out) and the first phase.

Alternatively, if the processor determines that the first additional phase is still powered down, then the program proceeds again to step 420 where any changes from internal power to external power are detected. In this case, for example, if the internal/external power switch 226 is set to external power in step 420 Force, the program proceeds to step 450 where any circuit paths between the second phase and the first phase are decoupled. As described above with reference to FIG. 3, one of the internal/external switches 226 is magnetically coupled to the control switch 315, which disconnects the 24 volt DC power supply that energizes the relay coil 314, regardless of the processor from the main control module 102. What is the "Ph B Ext Ena" control signal? In this manner, any circuit path between the second phase and the first phase is decoupled in step 450.

Using method 400 for automatically powering a power down phase, one of the power down phase tap positions can be maintained at one of the positions consistent with the tap positions of the other phases in a multiphase system. Therefore, when the power-off phase is re-energized, the multi-phase system is more likely to return to the balancing operation in a short period of time.
