| 摘 要： | 同塔双回线路在运行过程中两回线会产生静电和电磁耦合。当一线运行、另一线停运时, 在停运线路上产生幅值较高的感应电压和电流, 给停运线路的检修工作以及两站拉合地刀的操作带来不利的影响。文章以500 kV平西5312 线路为例, 利用PSCAD/EMTDC 电磁暂态计算程序, 计算、分析了影响静电感应和电磁感应电压和电流的相关因素, 为线路设计提供重要依据。

| Abstract: | Static and EM coupling occurs in double circuit line during operation. When one line is operative and the other is not, higher inductive voltage and current will occur in the inoperative line affecting maintenance work and switch operations Using 500 kV Pingxi 5321 line as an example, and using EM transient program PSCAD/EMTDC, this paper calculates and analyses factors affecting static and EM induced voltage and current. It provides valuable basis for line design. |

| Keywords: | 500 kV line double circuit inductive voltage and current EM transient calculation |
