Abstract

By field measuring and analysis the time-frequency characteristics of the electromagnetic interference in 500kV AC system switch operation, and propose that the electromagnetic interference of switch operation in secondary system manifest as damped oscillation. Simulate the 500kV AC system switch operation by MATLAB-SIMULINK software; get the simulation waveforms of the switch operation, comparing the similarities and differences between the simulation waveform and the field measuring waveform.
