Abstract:-In this paper, simulation evaluation is done to know the working of LFC by building
models in SIMULINK which helps us to comprehend the principle behind LFC which include the
challenge. Main function of fuzzy logic based frequency controller is to improve the dynamic
performance of frequency that means to keep the frequency balanced during sudden load change
in power system. Variations in load bring about drift in frequency and voltage which in turn leads
to generation loss owing to the tripping and also blackouts. These drifts might be reduced to the
smallest possible value by Fuzzy logic control method. Load cannot be constant when load varies
with time but gain values of conventional controller are constant. Thus to overcome the
conventional controller, fuzzy logic based controller is considered for load frequency control
problem. The simulation result shows that the proposed FLFC can provides good damping and
reduces the overshoot even in presence of the generation rate constraint.
