Abstract

This paper discusses for reduce the harmonics distortion of sensitive load against the induction motor drive load. Electronics devices are very sensitive load against harmonics. DVR proposed not only to improve PQ but also to reduce HD due to the presence of non-linear load. The DVR consists of injection transformer, filter, and ESS, VSI and control system. The basic function of injection transformer is to connect the DVR to the distribution network via the HV- wdg. In DVR LC filter can be achieved by eliminating the unwanted harmonics. The ESS can be suitable capacity. The ESS such as battery is responsible to supply energy in DC form. A VSI is a power electronics system consist of switching device which can generate a sinusoidal voltage. The disturbance is carried out with the help of d-q-0method. Simulation results carried out by MATLAB verify the performance of the given method.
