MLI-DSTATCOM Integrated With Distribution Transformer for Power Quality Enhancement in PDS

Abstract

This article offers a novel cascaded structure convertor (CMC)-primarily based mostly distribution-kind STATCOM integrated with distribution electrical device for medium voltage utility. The star-related, n-level CMC is connected to the winding faucets on the first windings of the electrical device to reap voltage strain discount and maintain a bendy affiliation voltage degree. Taking complete use of the spare potential of distribution electrical device, a compromise between cascaded cells depends and also the voltage pressure is completed. The CMC-based altogether DSTATCOM is controlled as a controlled current supply to inject compensation current to the first windings through the taps. A modified decoupled fashionable manipulate is planned to control the device. Simulation version and scale-down model area unit developed to verify the performance of the planned integrated structure. Simulation and experimental effects demonstrate the great performance of the planned structure for reactive power compensation.
