Electronic module for small hydroelectric power plant

Modern automation control systems of small hydroelectric power plants provide a constant frequency on the network. This regularization is achieved through positioning of the hydraulic director device that controls both water flow and electric machine speed. In order to control positioning of the director device, a high performance electro-hydraulic system is used. It contains a hydraulic cylinder, a proportional valve, a displacement transducer and a control electronic module. The electronic block controls the position and speed of the hydraulic cylinder. The electronic module allows local system intelligence, and shows good quality and reliability.
