摘要
针对137.5 MW机组保护系统频繁发生误动的现象,根据"二十五项反故障措施"的要求,对汽轮机危急保安系统的部分保护功能进行了优化,最大限度地防止了保护装置的误动和拒动。
Aiming at the misoperation phenomenon frequently encountered by the protection system of 137.5MW turbine unit, based on requirements of the ＂25 anti-failure measures＂, optimization is made for partial protection functions of the turbine emergency protection system （ manual/automatic protection logic）, which prevents at most misoperation and non-operation of relevant protection devices.
