中小水电站励磁系统的技术改造探索——以大新县中军潭水电站为例

我国许多中小水电站建于20世纪90年代以前,受当时科技、资金等条件限制,大部分中小水电站的核心技术水平较低,尤其是电站励磁系统,故障率高,停机频繁,发电效率和经济效益低。中军潭水电站是我国众多中小水电站之一,经常发生励磁故障,造成水电站多次被迫停产修理,为此,该电站选择静止式可控硅全控桥自并激励磁系统进行技术改造。运行结果表明,该励磁系统的基本技术性能、发展效率和经济效益明显,具有一定的推广应用价值。

Research on the Technical Reform of the Excitation System of Small and Medium-sized Hydropower Stations——A Case of Daxin County Zhongjuntan Hydropower Station

Many small and medium-sized hydropower stations in China were built before the 1990s.Because of the restriction on the technology at that time and the lack of fund,the core technology of most of the small and medium-sized hydropower stations lagged in the core technology,especially the excitation system.Some phenomena,such as the high fault rate,frequent shutdown,and low generation efficiency and economic benefit usually happened in the stations,like Zhongjuntan Hydropower Station.Thus,the station starts to choose static controllable silicon full-control bridge and to reform excitation system.The results show that the system is worthy of extension.
