福堂坝水电厂水轮发电机组过速保护改造

Retrofit of hydraulic turbine generator set in Futang Dam Water Power Plant

水轮发电机组过速保护系统主要用于防止机组过速事故对机组造成损坏,而过速保护装置及其自动化元件的可靠运行是确保过速保护系统正确动作的必要条件。本文对福堂坝水电厂过速保护系统的设置及存在的安全隐患进行分析,提出了过速保护的技改思路。

The over-speed protection system of Hydrogenerator sets is mainly used to prevent damage to the unit caused by the excessive speed accident of the unit,and the reliable operation of the over-speed protection device and its automatic components is a necessary condition to ensure the correct action of the over-speed protection system.This paper analyzes the setting of the over-speed protection system in Futang Dam water power plant and the hidden danger of safety,and puts forward the technical reform idea of the over-speed protection.
