High-voltage Series Capacitor

High-voltage series capacitor is mainly used to enhance the transmission capacity of high-voltage power transmission lines (220kV, 500kV, 750kV and others) and enhance the power angle stability of power transmission lines.

High-voltage series capacitor is mainly used to enhance the transmission capacity of high-voltage power transmission lines (220kV, 500kV, 750kV and others) and enhance the power angle stability of power transmission lines.

Series capacitor is a set of series capacitor compensation equipment in high-voltage power transmission system. Its typical single line diagram is shown as follows:



After the line is inserted with series capacitor, the transmitted power flow can be effectively improved. Taking 40-50% of the compensation degree as an example, the active power flow of the line can generally be increased by about 30%.
