山口小型水电站调速器的优化改造

Renovation of small governor of Shankou Hydropower Plant

黑龙江省山口小型水电站调速系统在运行中出现电液伺服堵塞、低负荷波动、轮叶操作油管振动、不具备一次调频功能、人机界面受损严重等问题,对调速器的控制回路和机械液压系统进行了改造。改造后调速器操作方便、运行稳定、可靠性提高。

Some troubles of the small governor of Shankou Hydropower Plant （located at Heilongjiang Province） oc- curred in operation l such as electro-hydraulic servomator block-up, fluctuation under low load operation, runner blade oil-pipe vibration, loss of frequency control function, man-machine interface injured seriously etc. , so the control circuit and the mechanical-hydraulic system of the governor are reformed, the details are described.
