Harmonics and Reactive Power Compensation of Three Phase Induction Motor Drive by Photovoltaic-based DSTATCOM

As a result of rapid advancement in electrical and electronics technologies, the application of power electronics is growing day by day due to the significant advantages offered. But as a downside of the same, extreme application of power electronic-based converters has caused the excessive emission of harmonics as well as reactive power in power system networks. Due to the harmonics emission by the power electronic converter-based drives, voltage at the point of common coupling (PCC) gets distorted and it creates problem for appliances of other industrial and domestic consumers connected at the same PCC. Apart from that the reactive power drawn by non-linear as well as LFP loads also causes the demand charges by the utility to increase and makes voltage regulation poor. This work presents the designing and simulation of a photovoltaic fed Distribution-STATCOM for compensation of harmonics and reactive power of a three phase induction motor based drive. Simulation work has been carried out in MATLAB/Simulink environment. The waveforms and THD data obtained in results verifies the capability of proposed DSTATCOM model for compensating harmonics and reactive power of induction motor drive.
