水电站的水轮发电机组设备改造是水电站自动化的重要内容。目前,我国很多水电站中除了转轮需要更换之外,水轮发电机组的运行状况尚可,但是超出力运行的情况较多,许多发电机的老化严重,无法满足水机超出力运行要求。因此,本文针对水电站水轮发电机组设备改造进行探索和研究。 Hydropower plant hydropower plant equipment transformation is an important part of hydropower automation. At present, in addition to the need to replace the runner in many hydropower stations in our country, the operating conditions of the hydroelectric generating units are acceptable. However, there are many cases of overrun operation, and many of the generators are seriously aged and can not meet the operation requirement of water exceeding the capacity. Therefore, this paper aims to investigate and research on the equipment modification of hydroelectric generating set in hydropower station.
