Abstract

This Paper discusses the effects of load parameters and their variations on power system frequency. In this study an interconnected three area hydro-thermal power system with conventional PI controller and fuzzy logic controller is selected. From the mathematical modeling of power system, frequency is a function of power system parameters and for small changes in these parameters leads to small deviations in the system frequency. In case of extreme ends of parameters, even for small changes in load power there will be a chance of instability in overall power system. This paper deals both stable and unstable cases for different parameter variations. Simulations are carried out in MATLAB/SIMULINK software.
