In recent years, a number of equipment abnormal events caused by operating overvoltage have occurred during the interruption of 35 kV shunt reactors, which jeopardizes the safe and stable operation of the grid. In order to explore the mechanism of operating overvoltage when 35 kV shunt reactor is cut off and the effect of various suppression measures, this paper carries out simulation analysis and research, mainly considers several factors to the effect of overvoltage, such as bus outlet, circuit breaker switching position and overvoltage protector.
