Shunt capacitors are widely used in power grid reactive power compensation.However,the insulation equipment may be damaged and the reliability of power system operation be affected by the overvoltage generated when shunt capacitor is withdrawing from the sysem operation.The single phase and three phase restrike models are built using ATP/EMTP transient state simulation software,and the overvoltage of shunt capacitor is simulated.Then the conclusion is drawn from the simulation and theoretical calculation,providing basis for the shunt capacitor selection and operation.
