摘　　要：针对输电线路工频参数测量过程中容易受到附近平行线路干扰的问题,采用EMTP程序,对与干扰紧密相关的线路间距、电流、换位情况、线路长度等多种因素进行了综合分析,得到了平行线路导致干扰变化的普遍规律,为线路参数测量的干扰分析提供了参考。The measurement of the transmission lines＂ frequency parameters is easily disturbed by the adjacent parallel lines. With the use of the EMTP program, many factors related to the disturbance are comprehensively analyzed, such as the distance between the transmission lines, the current, the transposition, and the length of the line conductors. The rules that how the factors influence the disturbance are found.The conclusion provides a reference for the analysis of the disturbance during the process of the measurement.
