在使用上述无功补偿装置对电网进行无功补偿过程中，当电网所需无功供应较少时，首先可通过静止无功补偿器11对电网进行无功补偿，改善电网的电压分布；而当电网中大功率非线性负荷不断增加，导致对电网的无功冲击不断上升时，则不仅可通过静止无功补偿器11对电网进行无功补偿，还可通过与静止无功补偿器11相连的本地投切电容器12、本地投切电抗器13、远方投切电容器21和远方投切电抗器22对电网电压进行调节，以进一步改善电网电压分布，从而提高电网电压的稳定性。In the process of using the above-mentioned reactive power compensation device to perform reactive power compensation to the power grid, when the reactive power supply required by the power grid is less, the static var compensator 11 can firstly perform reactive power compensation to the power grid to improve the voltage distribution of the power grid; and When the high-power non-linear load in the power grid continues to increase, resulting in a continuous rise in reactive power impact on the power grid, not only can reactive power compensation be performed on the power grid through the static var compensator 11, but also by connecting with the static var compensator 11 The local switched capacitor 12, the local switched reactor 13, the remote switched capacitor 21 and the remote switched reactor 22 regulate the grid voltage to further improve the grid voltage distribution, thereby improving the stability of the grid voltage.
在本实施例提供的无功补偿装置中，本地无功补偿子站1包括静止无功补偿器11，以及分别与该静止无功补偿器11相连的本地投切电容器12和本地投切电抗器13，而远方无功补偿子站2中包括的远方投切电容器21和远方投切电抗器22也均与该静止无功补偿器11相连，这就使得当电网中大功率非线性负荷增加，导致对电网的无功冲击上升时，不仅可通过静止无功补偿器11对电网电压进行调节，还可通过与该静止无功补偿器11相连的本地投切电容器12、本地投切电抗器13、远方投切电容器21和远方投切电抗器22对电网电压进行调节，从而能够改善电网电压分布，提高电网电压稳定性，进而满足电网安全稳定运行的需要。In the reactive power compensation device provided in this embodiment, the local reactive power compensation substation 1 includes a static var compensator 11, and a local switched capacitor 12 and a local switched reactor respectively connected to the static var compensator 11 13, and the remote switched capacitor 21 and the remote switched reactor 22 included in the remote reactive power compensation substation 2 are also connected to the static var compensator 11, which makes when the high-power nonlinear load in the grid increases, When the reactive power impact on the power grid rises, the grid voltage can be adjusted not only through the static var compensator 11, but also through the local switching capacitor 12 and the local switching reactor 13 connected to the static var compensator 11. , The remote switched capacitor 21 and the remote switched reactor 22 regulate the grid voltage, thereby improving the grid voltage distribution and improving the grid voltage stability, thereby meeting the needs of safe and stable operation of the grid.
示例性地，上述无功补偿装置包括的远方无功补偿子站2的个数可以为一个或多个，当该无功补偿装置包括的远方无功补偿子站2的个数为一个时，该无功补偿装置对电网电压的调节范围大于只适用静止无功补偿器11对电网电压的调节范围，而通过增加远方无功补偿子站2的个数，就使得要在扩展上述无功补偿装置对电网电压的调节范围的基础上，才能满足上述无功补偿装置要对每个远方无功补偿子站2的调节范围，因此，通过设置无功补偿装置中远方无功补偿子站2的个数，能够调节该无功补偿装置对电网电压的调节范围，以满足不同电网的无功补偿需求。Exemplarily, the number of remote reactive power compensation sub-stations 2 included in the reactive power compensation device may be one or more. When the number of remote reactive power compensation sub-stations 2 included in the reactive power compensation device is one, The adjustment range of the reactive power compensation device to the grid voltage is larger than that of the static var compensator 11 to the grid voltage, and by increasing the number of remote reactive power compensation sub-stations 2, it is necessary to expand the above reactive power compensation Only on the basis of the adjustment range of the device to the grid voltage can the adjustment range of the above-mentioned reactive power compensation device for each remote reactive power compensation substation 2 be satisfied.

For the switching switch selection, Those skilled in the art can choose according to the selected local switched capacitor 12 , local switched reactor 13 , remote switched capacitor 21 and remote switched reactor 22 , which are not limited by the embodiment of the present invention.
具体地，在使用上述无功补偿装置对电网进行无功补偿过程中，当电网所需无功供应较少时，可只通过控制母线111控制与其相连的晶闸管投切电容器112、晶闸管控制电抗器113和固定电容器114对电网进行无功补偿，改善电网的电压分布；而当电网中大功率非线性负荷不断增加，导致对电网的无功冲击不断上升时，则还可通过控制母线111控制与其相连的本地投切电容器12、本地投切电抗器13、远方投切电容器21和远方投切电抗器22对电网电压进行调节，增大上述无功补偿装置对电网电压的调节范围，以进一步改善电网电压分布，从而提高电网电压的稳定性。Specifically, in the reactive power compensation process of the power grid using the above-mentioned reactive power compensation device, when the reactive power supply required by the power grid is small, the thyristor switching capacitor 112 and the thyristor controlled reactor connected to it can be controlled only through the control bus 111 113 and fixed capacitor 114 perform reactive power compensation to the power grid to improve the voltage distribution of the power grid; and when the high-power nonlinear load in the power grid continues to increase, causing the reactive power impact on the power grid to continue to rise, the control bus 111 can also be used to control it. The connected local switching capacitor 12, local switching reactor 13, remote switching capacitor 21 and remote switching reactor 22 adjust the grid voltage, and increase the adjustment range of the reactive power compensation device to the grid voltage to further improve Grid voltage distribution, thereby improving the stability of grid voltage.
此外，还可利用灵敏度系数编制设备设定上述无功补偿装置中的本地投切电容器、本地投切电抗器、远方投切电容器和远方投切电抗器投切的优先级，以使得该无功补偿装置可根据电网的实际运行需要增加或减少无功供应，更好地改善电网的电压分布。In addition, the sensitivity coefficient compilation equipment can also be used to set the priorities of the local switching capacitors, local switching reactors, remote switching capacitors and remote switching reactors in the reactive power compensation device, so that the reactive power The compensation device can increase or decrease reactive power supply according to the actual operation needs of the grid, and better improve the voltage distribution of the grid.
示例性地，如图1所示，上述本地投切电容器12可以为断路器投切电容器，本地投切电抗器13可以为断路器投切电抗器，以使得在使用上述无功补偿装置对电网进行无功补偿时，可运用电网中已有的断路器5控制本地投切电容器12和本地投切电抗器13的投切，从而能够降低上述无功补偿装置的运行成本，实现电网的经济运行。Exemplarily, as shown in FIG. 1, the above-mentioned local switched capacitor 12 may be a circuit breaker switched capacitor, and the local switched reactor 13 may be a circuit breaker switched reactor, so that when using the above-mentioned reactive power compensation device to the power grid When performing reactive power compensation, the existing circuit breaker 5 in the power grid can be used to control the switching of the local switching capacitor 12 and the local switching reactor 13, thereby reducing the operating cost of the above reactive power compensation device and realizing the economical operation of the power grid .
类似地，如图1所示，远方投切电容器21也可以为断路器投切电容器，远方投切电抗器22也可以为断路器投切电抗器，以使得在使用上述无功补偿装置对电网进行无功补偿时，也可运用电网中已有的断路器5控制远方投切电容器21和远方投切电抗器22的投切，从而能够进一步降低上述无功补偿装置的运行成本，更好的实现电网的经济运行。Similarly, as shown in Figure 1, the remote switching capacitor 21 can also be a circuit breaker switching capacitor, and the remote switching reactor 22 can also be a circuit breaker switching reactor, so that when using the above reactive power compensation device to the power grid When performing reactive power compensation, the existing circuit breaker 5 in the power grid can also be used to control the switching of the remote switching capacitor 21 and the remote switching reactor 22, thereby further reducing the operating cost of the above reactive power compensation device, and better Realize the economical operation of the power grid.
进一步地，如图1所示，本地无功补偿子站1包括的本地投切电容器12和本地投切电抗器13个数可以均为一个或多个。当无功补偿装置中本地无功补偿子站1包括的本地投切电容器12和本地投切电抗器13个数为一个时，该无功补偿装置对电网电压的调节范围大于只适用静止无功补偿器11对电网电压的调节范围，而通过增加本地无功补偿子站1包括的本地投切电容器12和本地投切电抗器13的个数，就使得要在扩展上述无功补偿装置对电网电压的调节范围的基础上，才能满足上述无功补偿装置要对每个本地无功补偿子站1中本地投切电容器12和本地投切电抗器13的调节范围，因此，通过设置本地无功补偿子站1包括的本地投切电容器12和本地投切电抗器13的个数，能够调节该无功补偿装置对电网电压的调节范围，从而满足不同电网的无功补偿需求。Further, as shown in FIG. 1 , the number of local switched capacitors 12 and local switched reactors 13 included in the local reactive power compensation substation 1 may be one or more. When the number of local switched capacitors 12 and local switched reactors 13 included in the local reactive power compensation substation 1 in the reactive power compensation device is one, the adjustment range of the reactive power compensation device to the grid voltage is greater than that only applicable to static var The adjustment range of the grid voltage by the compensator 11, and by increasing the number of local switched capacitors 12 and local switched reactors 13 included in the local reactive power compensation substation 1, it is necessary to expand the above-mentioned reactive power compensation device to the grid. Only on the basis of the adjustment range of the voltage can the adjustment range of the above-mentioned reactive power compensation device be adjusted to the local switched capacitor 12 and the local switched reactor 13 in each local reactive power compensation substation 1.

When the number of remote switched capacitors 21 and remote switched reactors 22 included in the power compensation substation 2 is one, the adjustment range of the grid voltage by the reactive power compensation device is larger than that only applicable to the static var compensator 11. range, and by increasing the number of remote switching capacitors 21 and remote switching reactors 22 included in the remote reactive power compensation substation 2, it is necessary to expand the adjustment range of the above-mentioned reactive power compensation device to the grid voltage. In order to satisfy the above-mentioned reactive power compensation device, the adjustment range of the remote switching capacitor 12 and the remote switching reactor 13 in each remote reactive power compensation substation 2 must be adjusted. Therefore, by setting the remote switching The number of switching capacitors 21 and remote switching reactors 22 can further adjust the adjustment range of the reactive power compensation device to the grid voltage, thereby further meeting the reactive power compensation requirements of different grids.
