Abstract

According to the capacitor bank protection faults leading to the two explosive accidents of capacitors with internal fuse of 35 kV shunt capacitor bank in 500 kV substations

the computer simulation models of 35 kV shunt capacitor banks in 500 kV substation in Zhejiang Province were conducted.The protection signal values caused by different numbers of internal fuses disconnected and the over-voltage undertaken by the other normal capacitor elements and capacitor units were analyzed through simulation computation

And Related protection values of the relevant capacitor banks were raised.
