Abstract:750kV transformer is important in 750kV power grid and plays a major role in safe operation of power grid. The paper analyzes the causes of asymmetric three-phase winding parameters of 750kV transformer and establishes research model of Northwest 750kV transmission system, applies electro-magnetic transient simulation program to focuses on the impact of operating overvoltage caused by Three-phase Winding Parameter Asymmetry through several typical operating modes.
