A study of solutions to EMI of computer monitoring and control system in hydropower plant

Hydropower plant is a large energy conversion location, which suffers strong EMI. Its computer monitoring and control system works under a bad electromagnetic environment. Aiming at raising its ability against EMI, this paper makes a study on the solutions with the applications of some basic EMC techniques. The generator busbar, primary device, auxiliary equipment and transmission line are discussed as obvious interference sources. They also focus on computer room, course and transmission channel and system network as protective parts with important considerations. Many of those solutions can be efficient references for hydropower plant automation and production.
