| 摘 要： | 针对同塔双回线路中,一回线运行、另一回线停运检修时,在停运线路上产生的感应电压和电流是否威胁人身安全的问题,结合罗山灵州330kV输电线路实际工程,建立了基于电磁暂态分析程序ATP-EMTP的感应电压和电流仿真计算模型,计算分析了静电感应和电磁感应2种类型的电压和电流。仿真结果表明:330kV同塔双回线路一回线运行、另一回线停运检修时,停运线路上感应产生的电压、电流幅值远远超过人体的安全电压和安全电流,需对线路接地开关进行正确选择。

| Abstract: | Aiming at the problem that when double circuit transmission lines on the same tower, onecircuit is operating, and the other is stopping to overhaul, the induced voltage and circuit on theshutdown line whether menace personal safety for maintenance personnal, Combining with Luoshan-Lingzhou 330 kV transmission line project, establishes the induced voltage and circuit simulationcalculation model based on electromagnetism transient analysis program (ATP- EMTP), calculates andanalyzes the electrostatic induction voltage and current and electromagnetic induction voltage andcurrent. The simulation result shows that when double circuit transmission lines on the same tower,one circuit is operating, and the other is stopping to overhaul, induced voltage and current on theshutdown line far exceed the humans body safe voltage and current, so need to correctly select theground switch for line. |
