Abstract:
Power quality in electrical networks is one of the most concerned areas of electrical power system. Due to the use of non-linear loads and variation of load, various power quality problems such as sag, swell, harmonics, waveform distortion, voltage fluctuation occurs which result in malfunctioning of equipment. This paper is mainly concentrated to improve power factor, mitigate power quality problem and thereby reduction in THD to least minimum value can be obtained by using DVR. In DVR, shunt APF is designed to compensate the load current with supply voltage of 380V. Simulation results of DVR with PI or FUZZY controller are obtained with different load conditions using MATLAB.
