水电站冲击式水轮机组停机电制动技术应用分析

Analysis on Application of Electric Braking Technology in Impact Turbine Shutdown of Hydropower Station

水轮发电机组(特别是冲击式机型)的停机采用电制动技术方式在绿色水电工程中最为广泛应用。着重介绍厄瓜多尔Coca Codo Sinclair科卡·科多辛克雷水电站(简称CCS)冲击式水轮机采用电制动技术与传统的机械制动相结合的新型组合方式进行停机的过程试验所得出的数据分析及结论。这种新型组合制动方式对水轮发电机组停机过程的制动效果、实用性及特有绿色环保的属性。

Electric braking technology is widely used in green hydropower projects for shutdown of hydraulic generator units(especially impact type).This paper describes the process test of stopping impact turbine in Ecuador Coca Codo Sinclair(CCS)Hydropower Station by a new combination of electric braking technology and traditional mechanical braking.This new combined braking mode has good braking effect,practicability and environmental protection for the process of hydraulic generator unit shutdown.
