The 110 kV shunt capacitor banks in Changzhi 1 000 kV UHV(Ultra-high Voltage)substation characterized in large capacity and high voltage.Making sure the safe operation of the device and aiming to the phenomena of switching overvoltage and unbalance protection malfunction
some technical innovation measures were used such as double switching overvoltage protection(using low restriking circuit breaker and over damping device) and double differential current bridges.The result shows that the above problems are effectively restricted when shunt capacitor banks are running normally.Finally
the paper makes an additional description of the installation in operation and maintenance issues that need attention.
