摘要
Abstract
330 kV transmission line is an important part of the Northwest Power Grid,and its safe and sta-ble operation is related to the harmony and stability of society.Due to the long transmission distance of 330 kV transmission line,which can be more than 200 km,the terrain is complicated,and the span of the same line is not the same.When a lightning strike occurs,the span will affect the refraction and re-flection of the lightning wave propagating along the transmission line,thereby affecting the lightning re-sistance performance of the transmission line.As 330 kV lines generally use double-circuit towers to e-rect transmission lines,the phase sequence in different sections is not the same.Therefore,it is necessa-ry to study the impact of different phase sequence arrangements on the lightning resistance performance of the lines.The author uses EMTP transient simulation software to build a 330 kV double-circuit trans-mission line on the same tower lightning back striking model,discusses and analyzes the impact of diffe-rent span and different phase sequences on the lightning backstroke overvoltage of 330 kV transmission lines.关键词
