Abstract Combining into lines and substations, this article considers impulse corona and the frequency voltage of transmission lines affect 1000kV Substation lightning invasion wave. Establish impulsive corona model based on Corona V characteristic curve library. Using ATP-EMTP simulates of lightning invasion wave of 1000kV GIS substation. Simulation results show that: Corona can reduce the impact of lightning invasion wave amplitude and steepness, and the amplitude of over-voltage of substation equipment will reduce; In the negative half cycle of the power frequency voltage will increase the amplitude of over-voltage, and the positive half cycle of the power frequency voltage will reduce the amplitude over-voltage.
