An Inductively Coupled DSTATCOM using self and split capacitor supported Topology for Power Quality Enhancement

In this research paper, an inductively coupled distributed static compensator (DSTATCOM) for three phase three wire (3P3W) electric power distribution system (PDS) is proposed. Both self and split capacitor-based topology is implemented to showcase the power quality (PQ) behaviour for the uncontrolled rectifier load. The filtering mechanism is performed by following the generalized mathematical approach for the different circuit topology-based voltage source converter (VSC) by using icosφ algorithm. The MATLAB/ Simulink results prove that better potential control, potential balancing, source current harmonic reduction, and power factor correction are all benefits of the self-supported topology. Finally, the simulation analysis was completed from the proposed topology which also exposes the suitability for balanced loading state in PDS.

I. INTRODUCTION

Currently, the involvement of electrical traction system, renewable energy sources (RES), charging stations of electrical vehicle (EV) and some other non-linear loads, the usage of flexible transmission system (FACTS) device as well as high-power industrial dc supply systems are significant to meet the society demand [1]-[2]. But on the other side of the coin, the fast-increasing application of non-linear burdens are inevitably bringing PQ problems in the PDS and interconnected network [3]-[4]. The fast-increasing application of non-linear burdens causes notable harmonics problem in the PDS. These results the thoughtful problems such as the increasing in line loss, fluctuations in torque of AC machine, and interference to communication systems etc. The strict requirement as imposed by IEEE -519-2017 grid code is to improve the source side PQ by providing the harmonic compensation as well as improved power factor using DSTATCOM.
