摘要 简要分析了同塔双回线路感应电流和电压的产生原理,结合西宁至日月山750 kV同塔双回线路工程实际,应用ATP仿真软件进行了建模仿真计算,其计算结果表明同塔双回线路接地开关的电容、感应电压等参数可能超出IEC标准的B类开关限值,对类似工程设计具有重要参考意义。 The occurring principle of the induced current and voltage of double circuit transmission lines on the same tower is analyzed briefly. Based on the parameters of 750 kV Xining- Riyueshan project, the modeling and simulation calculation are carried out by ATP. According to the calculation results, the parameters of earthing switch in double circuit transmission lines on the same tower such as capacitance, induced voltage et al, may exceed the requirements of the switches of type B in IEC standards. It gives a reference for the design of the similar projects.
