Abstract Because of the simple wiring, less components and high sensitivity, open-delta voltage protection is widely used in 10kV shunt capacitors protection. With the development of the grid, a large number of shunt capacitors are put into operation in the grid, but shunt capacitor open-delta voltage protection malfunctions easily because of the initial unbalance. This paper analyzes the influence of initial unbalance of shunt capacitors open-delta voltage protection through unbalance capacitor, three-phase unbalance power voltage and the performance difference of discharge coil, and simulates by PSCD/EMTDC, which provides an important reference for the actual protection setting.
