摘要
结合一起发电机组双冷水中断事故案例,对双冷水保护逻辑进行探讨,提出优化原则、优化方案,从而降低双冷水保护误动与拒动的风险,从保护逻辑层面为机组安全稳定运行提高保障。
The double cold water protection logic is discussed with reference to a dou-ble cold water interruption accident in a power generating unit. Optimization principle and program are put forward to reduce unwanted action of double cold water protection and en-sure safe and stable operation of the unit from the aspect of protection logic.
