摘要
对一起励磁试验过程中失灵保护动作原因进行分析,发现失灵保护回路设计中存在的问题,拟定了有针对性的防控措施及技术改造方案并加以实施,达到了预期的效果,可为其他电厂同类试验及保护回路隐患排查提供参考。
The reason of a failure protection misoperation incident in the excitation test is analyzed, and the design problem of the failure protection circuit is found. The prevention and control measures and technology modification scheme were developed and implemented which achieved desired effects and thus can provide references for other power plant in similar tests and hidden troubles detection of protection circuit.
