To understand overvoltage change at a 500 kV autotransformer neutral when the neutral is grounded from directly to through a small reactance,the overvoltage at autotransformer’s neutral and entrance is calculated respectively by ATP-EMTP,and the overvoltage for adopting small reactance grounding is analyzed to determine overvoltage protection and insulation coordination.
为研究500 kV自耦变压器中性点由直接接地改成经小电抗接地后其各种过电压水平变化情况,笔者利用ATP-EMTP电磁暂态程序对主变中性点和端部过电压进行详细计算,对变压器中性点接小电抗后的各种过电压水平进行了分析并确定其过电压的保护方式、绝缘配合,得出安徽省500 kV肥西变主变中性点经5Ω电抗器接地后,加上氧化锌避雷器保护,可维持原绝缘水平不变的结论,对解决肥西变500 kV电网中单相接地短路电流超过开关额定遮断电流的问题具有重要意义。
