Research on Multi-function Automation Device for Small Hydropower Stations Based on
CAN Bus Zeng Min1, Jiang Bo1, Zhu Qicheng2, Zhong Churen2 (1.Beijing Institute of Technology of Chemical & environment,Beijing 100081,China; 2.Beijing SiFang-LiShui Automation Co., Ltd, Beijing 100085,China) Abstract: In order to solve the problems of low control technology, obsolete device and frequent accidents in many small hydropower stations in our country, improve the technology of automation in small hydropower stations, the multi-function automation device for small hydropower stations is composed of many functional modules which are connected by CAN Bus. The device has the functions of generator protection, measuring and control, sychrolization control, PLC, remote communication and so on. The communication inner the device is fast and reliable, and the performance of anti-famming is strong. The device can run alone to complete the function of automatic control for small hydropower stations, and when many devices run together they also can communicate with PC conveniently to form monitor and control system in small hydropower stations.
