Analysis of Lightning Overvoltage on 110?kV Transmission Lines Based on ATP-EMTP
The article is based on ATP-EMTP software to simulate and analyze the lightning resistance performance of 110 kV transmission lines under lightning overvoltage conditions,and explore the effects of grounding resistance,lightning current waveform,and tower air gap length on the lightning resistance level and winding lightning resistance level of transmission lines.The simulation results show that these factors have a significant impact on the lightning resistance performance of 110 kV transmission lines,which can provide scientific basis for the design and improvement of transmission lines.
