摘要/Abstract

摘要： 巩义豫联电厂300MW机组汽轮机在停机惰走期间再次挂闸时，调门突然开大、转速迅速飞升导致汽轮机的超速保护(OPC)动作，针对上述现象进行了分析和处理，取得了良好的效果。

Abstract: In Gongyi Yulian Power Plant, when the 300MW unit turbine was latched on again during its coasting operation after it was shutdown, the opening of the adjust gate was increased suddenly and rapidly; the rotate speed of the turbine was increased sharply; and the overspeed protection of the turbine was acted. The problems mentioned above were analyzed and treated, and favorable effect was obtained.

Key words: digital electro hydraulic control system (DEH), coasting operation after shutdown, PID adjuster, overspeed protection, fault analysis
