Power Quality Enhancement in Multi-Feeder Distribution System using Mf-Upqc Device

Abstract

The significant usage of power semi-conductor devices in modern single or multi-feeder distribution system is increasing a lot in present situation. The non-linear characterization of power distribution is highly responsible for degradation of power-quality standards. The usage of large-sized non-linear loads provokes the harmonic pollution, voltage interruptions, voltage sag/swell issues are the key problems faced by distribution systems. Over the various compensation methodologies, the highly validated universal device is Unified-Power Quality Compensator. The multi-feeder universal devices play a prominent role and provide the attractive performance with improved characteristics in multi-feeder distribution system. In this work, Multi-Feeder UPQC device is used to compensate all voltage and current related PQ issues in multi-feeder distribution systems and also furnishes load-sharing between adjacent feeders, reduce the power-shortages, maximizes the stable performance. The performance evaluation of proposed MF-UPQC is verified under various case studies with the help of Computer-Simulation tool, results are validated with improved PQ features.

A novel reduced-switch multi-level inverter based multi-device universal power-quality conditioner for PQ enhancement

“…The investigation conducted in [26], [27] explores the synchronous reference frame (SRF) control and instantaneous real-power (IRP) control schemes [28], [29], which are widely recognized methods for extracting reference voltage-current in power systems. These methods are subject to limitations such as intricate transformations, intricate mathematical logic, and response latency.…”

Novel multi-device unified powerquality conditioner for powerquality improvement

“…The symmetrical instantaneous control theory (SICT) [18], instantaneous real-power control theory (IRP) [19], and synchronous reference control theory (ID-IQ) [20] are prominent control objectives explored in [21]. The above control objectives are fated-out due to complex dual-transformations, more mathematical analysis and high delayed signals.…”
