广东某抽蓄电站双机甩负荷后轴线变化原因剖析及处理

Analysis and treatment of the causes of axis change after load shedding of double-units in a pumped-storage power station in Guangdong province

发电电动机转子是抽水蓄能机组的核心部件之一,本文介绍了广东某抽水蓄能电站发电电动机双机甩负荷后,上导轴承摆度明显增大,经过原因分析及处理,解决了摆度问题。对其它抽蓄及常规电站甩负荷后摆度问题的分析和处理工作具有一定的借鉴作用。

The rotor of a generator motor is one of the core components of a pumping storage unit.In this paper,it is introduced that the swing of upper guide bearing is obviously increased after load shedding of double-units of generator motor in a pumping storage power station in Guangdong province,and the problem of swing has been solved after cause analysis and treatment,with a certain reference effect for the analysis and treatment of the problem of swing after load shedding in other pumped-storage and conventional power station.
