摘要
针对李家峡水电站4号机组调速器换型后存在的问题,提出了两套改造方案。分析认为采用第二套方案可以在很大程度上降低项目投资成本,缩短改造工期。改造后的静态试验和动态试验证明,调速器所有技术指标均达到了改造要求和标准要求,达到了改造目的。
In the light of the problems existed in changing governor for No.4 unit in Lijiaxia Hydropower Station, this paper proposes two retrofit schemes, and also recommends that the second scheme can reduce project cost and shorten the time limit for the project. The static test ＆ dynamic test after retrofitting show that all of the technical indexes meet the requirements of retrofit ＆ standard. The retrofit obtains the expected effect.
