摘要/Abstract

摘要： 乌溪江电厂 # 5机组是计算机监控、无人值班、少人值守的关门运行机组，改造前存在停机所需的时间长，机械制动时因摩擦而引起机械疲劳以至变形龟裂的问题，且自动化水平不高。通过对 # 5机组进行加装电气制动的改造和相关试验的探索，较大程度地改善了机组的停机运行性能、提高了环境质量和机组控制的自动化水平。

Abstract: The unit #5 of Wuxijiang Hydropower Plant is monitoried and controlled by computers and operated at the “unmanned on duty” mode. But there were some problems in its mechanical brake system, including longer time needed for stopping by mechanical brake, mechanical fatigue, deformation and cracking due to friction, and lower automation level. To solving these problems, the electrical brake stopping system has been adopted and relevant test has been carried out for investigating. Now the unit stopping performance is improved, the environment quality and automation level are raised after the brake system reformation.

Key words: hydro turbine generator, electrical brake, mechanical brake
