摘要
各类非对称接地故障在中压配电网中是非常普遍的,因此在电气工程教学过程中对于10kV配电网故障的产生、过程、危害以及防治等进行研究和授课具有十分重要的现实意义。本文使用电力系统仿真工具PSCAD/EMTDC构建了10kV配电网的全工况仿真平台,并建立了并行仿真环境,在此基础上可开展对中性点不同的接地方式、四类不同消弧线圈的性能进行仿真研究和教学,同时仿真结果可以与10kV高压模拟网试验数据进行对比。本文的讨论对电气工程课程的教学和工程实践具有一定的参考价值。
Asymmetric grounding fault is very common in medium voltage distribution network, so it is essential that students understand the production, process control and other hazards of grounding fault in teaching of electrical engineering courses. This article constructs 10kV distribution network simulation platform with the power system simulation tool PSCAD / EMTDC, and establishes the parallel simulation environment. On this basis students can carry out performance simulation research about different neutral grounding modes and four different are suppression coils, and the simulated result can be compared with the experimental data from 10kV high-voltage testing. The discussion is helpful for the teaching of electrical engineering.
