Voltage reactive power compensation device with capacity equal difference adjustment

A voltage reactive power compensation device with capacity equal difference adjustment comprises a controller, an isolation switch device, an on-load self-coupling voltage regulator, a series reactor and a power capacitor bank, the front end of the isolation switch device is connected to a line, and the rear end of the isolation switch device is connected to the input end of the on-load self-coupling voltage regulator. The output end of the on-load self-coupling voltage regulator is connected to the input end of the series reactor, the output end of the series reactor is connected to the power capacitor bank, the controller is connected to a line and used for collecting line information, and the controller is further connected with the on-load self-coupling voltage regulator through a control cable and used for sending gear shifting signals. Line information is collected through the controller, and then a gear shifting signal is sent to control the gear change of the on-load self-coupling voltage regulator, s
