摘　　要：为了保证输电线路电压和电流的对称性,当输电线路超过一定长度时需要进行换位。本文对三段换位法以及九段换位法进行了理论分析。并利用ATP-EMTP建立了典型750k V线路的计算模型,仿真分析了不同换位方式的效果。通过仿真计算可知对于同杆架设的双回路输电线路,九段换位法效果明显优于三段换位法。In order to ensure the symmetry of voltage and current in the transmission line, transposition is necessary when the transmission line is over a certain length. In this paper, the three sections transposition method and nine sections transposition method are analyzed in theory. And the model of 750 k V transmission lines is set up to calculate the voltages of three phases by using ATP-EMTP. The symmetry effects of different methods are analyzed. It can be seen that nine sections transposition effect is better than three sections transposition method.
