Power Quality Control using Hybrid Active Power filters

Abstract

These power quality problems reduce the life time and efficiency of the equipment. Thus, to enhance the performance of the consumer equipment and also the overall performance of the system these problems should be mitigated. The main affect caused by these problems is the presence of harmonics. This leads to the overheating of the equipment, insulation failure and over speeding of induction motors etc. The solution to overcome these problems is to filter out these harmonics. For this purpose there are many filters topologies present in the literature. In this project a hybrid filter which is a combination of shunt active filter and shunt passive filter is studied. This project presents the control strategy to control the filter in such a way that the harmonics are reduced. The proposed control strategy is simulated in MATLAB SIMULINK and the results are presented.
