Inductively coupled distributed static compensator for power quality analysis of distribution networks

Abstract

<span lang="EN-US">In this research paper, an inductively coupled distributed static compensator (IC-DSTATCOM) for three phase three wire (3P3W) electric power distribution system (EPDS) is proposed. The contraction of power quality (PQ) was marked as a perilous droop mode bump into direct coupled distributed static compensator (DC-DSTATCOM). To regain the PQ, inductive coupling transformer is assisted in conjunction with DC-DSTATCOM. The system equivalent circuit of IC-DSTATCOM is accomplished by take into account of impedance of both transformer and DC-DSTATCOM to reveal the filtering technique. The filtering </span><em><span lang="EN-US">icos</span><span lang="EN-US">∅</span></em><span lang="EN-US"> mechanism is performed by following the generalized mathematical approach using MATLAB/Simulink. A case education is reviewed in detail to illustrate the performance of both DC-DSTATCOM and IC-DSTATCOM. The IC-DSTATCOM is amplified healthier as compared to other in terms of harmonics shortening, good power factor, load balancing, and potential regulation. To examine the effectiveness, simulation outputs of the IC-DSTATCOM with different PQ parameter indices are presented by following the benchmark measure of IEEE-2030-7-2017 and IEC-61000-1 system code.</span>

Power quality conditioning using two-level buck inverter based DSTATCOM

“…Among all varieties of CPD, distributed static compensator (DSTATCOM) is common types of shunt compensator [8]- [10]. In view of improved design aspect, the LC coupled buck voltage source inverters (VSI) based DSTATCOM is proposed for providing the actual and reactive power in the PCC for the PQ improvement [11], [12]. This buck inverter is designed by considering the aspect of modular design, suitable selection of inductor, variable output power, and flexible for additional connection of the elements [13]- [15].…”

Cascaded H-bridge multilevel inverter-based DSTATCOM with an artificial neural fuzzy inference systembased controller

“…Any short circuit does not lead to complete damage to the inverter and a short circuit is incomplete by the dc link inductor [4]. However, the current source inverter requires a bulky inductor and commutation capacitor, which will make the system bulky [5]. The voltage source inverter based multilevel requires only a capacitor on its dc side and the size of the inverter system is less as compared to the current source inverter.…”
