Hydropower Station integrated automation system is secure, stable and efficient operation of an important guarantee. Comparing the rapid development of China's hydropower, but the level of automation has not high. In recent years as computer and electronic information technology and the rapid development of increasingly mature, technologically advanced, reliable computer integrated automation system began to be widely used. At present, domestic hydropower station in the adoption of automatic control computer monitoring technology is the initial stage, in large and medium-sized hydropower stations, with imported computer monitoring system set mainly in small and medium-sized hydropower stations, as technology, capital and other aspects, to adopt the Development of domestic computer-based monitoring system, using imported equipment or hardware, software independent development of the hydropower station computer monitoring system. In this paper, the hydropower station at home and abroad integrated automation system in-depth study on the basis of the characteristics of the project, completed a small hydropower integrated automation system design. In this paper, a unit suitable for small hydropower control mode, and flow control unit in the full grasp on the basis of the PLC to complete the selection, I / O point configuration, the crew is given a detailed automatic on / Stands flow chart. And on the basis of this part of the design of the police unit design.
