POWER FACTOR CORRECTION SYSTEM USING MATLAB WITH DIFFERENT LOADS

The present work successfully developed and simulated an Automatic Power Factor Correction (APFC) system using MATLAB/Simulink under different load conditions. The proposed system was tested with resistive, inductive, and combined RL loads to evaluate its performance under varying operating conditions. Simulation results demonstrated that load variations significantly affect the power factor and reactive power demand of the system. An automatic capacitor bank switching mechanism was implemented to compensate for the reactive power requirement according to the load condition. The controller continuously monitored the power factor and connected the required capacitor banks whenever the power factor dropped below the specified limit. As a result, the system maintained the power factor close to unity and reduced reactive power consumption. The simulation results indicated a considerable improvement in power factor, reduction in line current, minimization of transmission losses, and enhancement of voltage regulation after compensation. Therefore, the proposed APFC system provides an effective solution for maintaining a high power factor under continuously changing load conditions and improving the overall efficiency of electrical power systems.
