| 摘 要： | 采用电磁暂态程序,建立了500 kV/220 kV同塔四回线路模型。仿真计算了220 kV东莞~黎贝线路在四种工况下的感应电压与感应电流,并为东莞站侧220 kV接地刀闸选型提供依据。结果表明,当220 kV东莞~黎贝一回线路停运、一回线路投运,500 kV东莞~福园一回线路停运、一回线路投运时,220kV东莞~黎贝线路上的感应电压、感应电流达到最大值;东莞站侧的220kV接地开关可按照B类选择。

| Abstract: | A model of 500 kV/220kV four-circuit transmission lines on same tower is built by use of electromagnetic transient program （EMTP）. Induced voltages and currents on 220kVDongguan～Libei transmission lines are simulated and calculated under four conditions in this paper, and provide the basis for 220kV grounding switch selecting in Dongguan substation. The results show that, Induced voltages and currents reached the maximum when one of the 220kVDongguan～Libei transmission line Outage, another one operation, one of the 500kV Dongguan～Fuyuan transmission line Outage, another one operation. Type B grounding switch is recommended to choose in Dongguan substation. |
