| 摘 要： | 在对某电厂发电机改造后的100%定子接地保护装置进行调试时发现,原来的改造方案无法满足100%定子接地保护的要求。文章对原来改造方案和调试过程中出现的问题进行了讨论分析,找出了出现问题的原因,并据此对原来的保护方案进行了修改。对修改后的方案进行了调试,调试结果表明,修改后的保护方案解决了原保护方案存在的问题,完全满足了100%定子接地保护的要求。

| Abstract: | In the course of debugging the 100% generator stator grounding protection after retrofitting,it was found that the original retrofitting scheme failed to satisfy the requirements for 100% stator grounding protection.The paper analyzed the problems occurring in the original retrofitting scheme and the debugging course and found out the cause of problem.Based upon the analysis,the original retrofitting scheme was amended and the amended scheme was debugged.The debugging results showed that,the amended protection scheme solved the problems existing in the original protection scheme,quite satisfied the requirements for 100% stator grounding protection. |
