功果桥水电站发电机调速器的三机冗余控制

Three Machine Redundant Station Generator Governor Control Gongguoqiao Hydropower

水电站发电机调速器为了获得较高的可靠性,电气部分主要采用双机控制和三机控制;而机械部分主要采用双比例阀作为电液转换装置的冗余控制。本文着重从电气和机械两方面介绍功果桥水电站调速器的控制原理,实际运行证明该结构成熟可靠。

The governor for hydropower station is composed by electrical part and hydraulic part, in order to enhance the stability of the governor, two or three main control processors is often adopted by the electrical part;double proportional valves as electro-hydraulic component is usually adopted by the hydraulic servo system. This paper introduces the control principle of the governor of Gongguoqiao hydropower station by the electrical part and hydraulic part.
