摘要
针对中小型发电机定子接地保护运行中无法避开不平衡电流出现的误动,分析原因,提出了改进方案。该方案经试运行半年余无误动,效果良好。
To deal with the unbalance current incorrect operation in the running of medium and small size generator stator ground fault protection, by analyzing and put forward the improvement scheme. After more than half of a year＇s tentative operation, it is proved effective.
