An Approach in Power Quality Enhancement Using DVR for Three Phase Induction Motor Drive

Abstract

Abstract. This paper focuses on the advancement of electric power quality tendencies of an induction motor as well as improving the consequence on account of the prolonged duration voltage discrepancy. The proposed mitigating device is a brand new topology of a DVR. This device is often familiar to minimizing the impact unusually high voltage variations while making use of highly effective custom electric power equipment that is to say the Dynamic Voltage Restorer (DVR). It contains an electric power storage device, filtration systems, voltage source inverter and also injection transformer. There are numerous categories of regulating approaches being employed for mitigation of abnormal voltages. The proposed control approach of this device will be based upon the "abc to dqo" conversion methodology employed. The demonstration outcomes can be found in several circumstances of sag, swell and additionally harmonic disorder in the supply voltage which exhibits the compensation abilities of DVR. The performance of suggested strategy is examined with the aid of computer demonstration through the use of MATLAB/Simulink software.
