Abstract

The power quality problems would reduce the lifetime and efficiency of the equipment. The highly dependent end user equipment will be affected by quality of power delivered. However, the various external and internal factors have an effect on the eminence of power distributed to the end user. They are like voltage and frequency variations, faults, harmonics, outages etc. Thus, to improve the performance of end consumer equipment and the system these problems should be minimized or completely cancelled out. The main affect caused by these problems is the existence of harmonics (both current and voltage harmonics).The solution to overthrow these problems is to filter out the harmonics. In this paper a hybrid filter of shunt active filter and shunt passive filter configuration is used. And also the paper confers the hysteresis control strategy to control the filter in such a way that the harmonics are reduced. The proposed control strategy and overall power quality improvement technique is simulated in MATLAB SIMULINK and the results are presented. Keywords: Harmonics, Non-linear load, Active power filters, Hybrid filters.
