摘　　要：为解决强电磁干扰下的高压输电线路参数测试问题,对输电线路正序参数传统测试方法的不足进行分析,提出便于现场实现的新方法——基于倒相法的单相加压法,并推导相应的计算公式,通过理论分析和现场实际测试验证了该方法的可行性。In order to measure the parameters of high voltage transmission lines in intense electromagnetic interference, the defects of the traditional method for positive sequence parameter of HV transmission lines are analyzed, A new method based on phase inversion with single-phase supply that could realize conveniently is presented, and the computing formulas are proposed too. The theoretical analysis and the field testing results indicate that the method could work effectively and with high precision.
