Autotransformer Employing UPFC (Unified Power Flow Controller)

Abstract

This article proposes a new autotransformer. The article explains principle working and significant steps for processing involves for a new unified power flow controller (UPFC) topology defined by use of autotransformer. Device information could be used to integrate a three-phase system. In comparison to the traditional UPFC topology, something that implements two three-phase transformers established as series and parallel transformers, the proposed circuit incorporates three single-phase transformers to enforce a three-phase UPFC system. Additionally, by applying a full-and half-bridge connector structure, the proposed topology is sufficiently efficient with regular power hardware and control strategies. This publication refers to the techniques used only to control the recommended topology. The technology and research project findings corroborate the usefulness of the proposed UPFC topology.
