Simulation Analysis of Lightning Strike at Traction Substation
Feng Ding · Railway Standard Design · 2013
According to the requirements of lightning protection at traction substation,through selecting the lightning current parameters and through simulation analysis on electromagnetic transient state,the author makes a discussion on the ground surface potential distribution of the traction substation after being struck by the lightning.Furthermore,the author puts forwards not only the safety distance of electrical equipments which are in operation,but also the method of reducing the lightning overvoltage.The author points out that,the impulse wave of lightning current should be considered adequately in grounding design,and the targeted safety measures should be adopted so as to make the lightning protection project at traction substation more safe,reliable,economic and reasonable.
