AN INTELLIGENT DISCONTINUOUS CONTROL STRATEGY FOR HYDROELECTRIC GENERATING-UNIT

An intelligent discontinuous control strategy for water turbine regula tion is presented in this paper. Taking reliability and the static and dynamic performance of the system as the ultimate goal, it combines t he classical fuzzy control theory and tri-state valve technology to fo rm a discontinuous controller. This results in a simplified water turb ine governor, both in software and hardware, The proposed control stra tegy greatly improves system performance and reduces the cost by total ly eliminating the electro-hydraulic transducer, Simulation results sh ow it has a satisfactory performance.
