Research of Lightning Over-Voltage and Simulation Program of Substation Based on EMTP

Abstract:

High voltage substation is the junction station of electrical power system. In order to conduct lightning over-voltage simulation and analysation of couple of substations rapidly and intuitively, a serialization supposed simulation program of substation is developed based on the research of EMTP kernel and data format. Model of impulse grounding resistance and improved leader progression is included in the program, which enhance the accuracy as much as possible and satisfying the demand for emulation of different type and voltage level. Through the simulation of some 500kV high voltage substation, the influence to lightning over-voltage of different system operating plan and lightning strike spots is analyzed, which verifies the validity and convenience of the program.
