摘　　要：针对输电线路走廊紧张的现状，结合某电力公司提供的工程数据，利用EMTP软件对长兴至步泾变电站间的35／10kV同杆并架三回输电线路建模，仿真计算了当一回线路停运时，其余两回线路在其上产生的感应电压大小，探讨了三相导线排列方式及相邻线路对该感应电压的影响，并对怎样减小该感应电压提供了一系列的建议和措施。In view of the current stress situation of the power transmission lines corridor tension and in accordance with the data provided by one Electric Power Supply Company,the simulation model of the EMTP software had been created for the 35/10kV three multi - circuit transmission lines on same tower between Changxing and Bujing Substation. The induced voltage of one transmission line was simulated and calculated when the other transmission lines were operating normally. The impacts of adjacent lines and the three - phase wire arrangement on the induced voltage were discussed. A series of recommendations and measurements for how to reduce voltage were discussed.
