Power Quality Enhancement in a Motor Manufacturing Industry using SVC

Abstract: Power quality is a significant concern in motor manufacturing industry because of the widespread use of inductive loads. These include induction motors, welding machines, variable frequency drives and testing equipment. These loads can cause poor power factor, voltage fluctuations, excessive reactive power demand and harmonic distortion. As a result this leads to increased energy losses and reduced equipment lifespan. This study presents a detailed examination of how to improve power quality in a motor manufacturing industry using a Static Var Compensator (SVC).The proposed system uses a SVC which includes Thyristor Switched Capacitors (TSC) and Thyristor Controlled Reactors (TCR) to provide reactive power compensation.By continuously monitoring system parameters such as voltage, current, and reactive power the SVC responds in real time to load variations thereby maintaining the power factor close to unity and stabilizing the bus voltage. The performance of the SVC-based compensation plan is assessed through simulation studies conducted under different operating conditions. The results demonstrate significant improvement in power factor and enhanced voltage regulation at the point of common coupling (PCC). Additionally overall system efficiency is improved and compliance with IEEE power quality standards is achieved. According to the study's findings SVC is a practical and affordable way to enhance power quality in motor manufacturing sectors with highly variable and inductive loads.
