Power Quality Enhancement in Induction Motor Drives by Using Custom Power Device

Original scientific paper This paper focuses on the advancement of electric power quality tendencies of an induction motor as well as alleviating the consequence on account of the prolonged duration voltage discrepancy and also quite a short time period voltage variance of these kinds of that over voltage, under voltage continuous interruption, impermanent voltage fall together with voltage climb or maybe an entire disappearance of voltage. The proposed alleviating device is a brand new topology of a dynamic voltage restorer (DVR). A DVR is often familiar to alleviating the impact of unusually high voltage variations while making use of a highly effective custom electric power equipment that is to say dynamic voltage restorer. It contains an electric power storage device, filtration systems, voltage source inverters and also injection transformer. There are numerous categories of regulating approaches being employed for mitigation of abnormal voltages. The proposed control approach to DVR will be based upon the 'abc to dqo' conversion methodology employed. The demonstration outcomes can be found in several circumstances of sag, swell and additional harmonic disorder in the supply voltage which exhibits the reimbursement abilities of DVR. The performance of suggested strategy is examined with the aid of computer demonstration through the use of MATLAB/SIMULINK software.
