Highlights
The aim of the present work is to obtain restoration of rated frequency
The disturbed frequency is restored to normal frequency by reducing the feedback path gain while during under loading feedback path gain is increased to obtain the return of normal rated frequency
Res. 6(9), 235-242 and ErtuğrulÇam in their work “Fuzzy logic controller in interconnected electrical power systems for loadfrequency control” [4] have provided a fuzzy gain scheduled proportional and integral (FGPI) controller for load frequency control of two area interconnected power system. It is shown through simulations of power system that FPGI controller is good enough for damping out oscillations which results from load disturbances
Summary
The aim of the present work is to obtain restoration of rated frequency After training the ANN provides the necessary feedback path gains for unknown levels of overloadings and under loadings respectively. Overloading causes reduction of frequency below its rated value 50Hz while under loading causes increase in frequency beyond 50Hz.Under both the conditions it is necessary to bring back the disturbed frequency to its normal frequency i.e. 50Hz. The present paper uses Simulink approach on MATLAB to establish recovery of frequency to its normal value.
