Abstract
Hydro power plant plays an important role in a safe, stable and efficient
operation of electric power systems, Performance of hydro power in terms of
frequency and power control increasingly important. This is as a result of
sophistication of hydro power plant dynamic modeling.
In this thesis, Finchaha hydro power plant dynamic model, frequency and
power control simulation has been performed for different operating
conditions. Then, for Grid Connected operation and Isolated Operation
power response has been investigated.
An intelligent governor has been design by using a fuzzy logic controller
replacing the conventional governor control of Frequency and Power on
Matlab Simulink.
The simulation result show that the overall system output performance can
be improved using the proposed fuzzy logic governor, the fuzzy logic
controller resulted less percentage overshoot (0.505%), fewer settling time
(2.8sec) and less rise time (439.153ms) as compared to 17.059%, 5.81sec
and 717.643ms for PID controller under grid operation, for Isolated
operation to fuzzy logic controller resulted less percentage overshoot
(0.465%), fewer settling time(2.671sec) and less rise time (1.171sec) as
compared to 3.646%,4.32sec and 1.429sec as compared to existing PID
controller
