Dynamic Modeling And Active Power Control Of Hydro Power Plant Using Fuzzy Logic Controller Case Of Finchaha Hydro Power Plant

Hydro power plant plays an important role in a safe, stable and efficientrnoperation of electric power systems, Performance of hydro power in terms ofrnfrequency and power control increasingly important. This is as a result ofrnsophistication of hydro power plant dynamic modeling.rnIn this thesis, Finchaha hydro power plant dynamic model, frequency andrnpower control simulation has been performed for different operatingrnconditions. Then, for Grid Connected operation and Isolated Operationrnpower response has been investigated.rnAn intelligent governor has been design by using a fuzzy logic controllerrnreplacing the conventional governor control of Frequency and Power onrnMatlab Simulink.rnThe simulation result show that the overall system output performance canrnbe improved using the proposed fuzzy logic governor, the fuzzy logicrncontroller resulted less percentage overshoot (0.505%), fewer settling timern(2.8sec) and less rise time (439.153ms) as compared to 17.059%, 5.81secrnand 717.643ms for PID controller under grid operation, for Isolatedrnoperation to fuzzy logic controller resulted less percentage overshootrn(0.465%), fewer settling time(2.671sec) and less rise time (1.171sec) asrncompared to 3.646%,4.32sec and 1.429sec as compared to existing PIDrncontroller
