摘要
在分析某水电厂的水机一级过速保护的设计原则和组成部分基础上,重点探讨了在在甩负荷试验中的水机一级过速保护的保护误动作事故问题,并相应提出改进的优化措施,实践证明,设备改造后能够消除保护动作不可靠的隐患。
Based on the design principle analysis of a certain power plant water over speed protection and its constituent parts, the paper mainly discusses the protection misoperation accident problems during overspeed protection of load rejection test, and puts forward corresponding improvement of optimization measures. Practice has proved that the equipment reform can eliminate protection operation unreliable hidden trouble.
