Compensation scheme for power quality improvement in present power system

The power quality (PQ) management is the key issue in electrical power system and industries are facing this issues around the world. The hybrid filter configuration with PI Controller is more efficient scheme for the improvement of power quality in power system. The main purpose of this work is to reduce the effects of Harmonics in a cost effective by mitigating both voltage and current harmonics generated in an electrical power system owing to the presence of non linear loads. This paper shows comparative study of a simple filter circuit, circuit with hybrid filter and a circuit with hybrid filter using P-I controller. The systems are modeled by using SIMULINK in MATLAB and performance is observed. The simulation results reveal that the proposed method of hybrid filter with PI controller is the better solution for improving power quality.
