DYNAMIC VOLTAGE RESTORER: A SOLUTION FOR POWER QUALITY ENHANCEMENT

Abstract

This paper explores the use of Dynamic Voltage Restorers (DVR) as a robust solution for improving power quality in electrical distribution systems. Power quality issues, such as voltage sags, swells, and flickers, can significantly disrupt the operation of sensitive equipment and impact overall system reliability. The proposed DVR effectively mitigates these disturbances by injecting the necessary voltage to restore the desired voltage level at the load point. This study presents a comprehensive analysis of the operational principles of DVRs and their role in enhancing voltage stability and power quality. Through simulation studies, the performance of the DVR is evaluated under various disturbance scenarios, demonstrating its effectiveness in reducing total harmonic distortion (THD) and maintaining a stable voltage profile. Additionally, the paper discusses advanced control strategies that optimize DVR performance in real-time applications, highlighting its adaptability to dynamic load conditions. The findings underscore the potential of DVR technology as a critical component in modern power systems, offering a practical solution to the growing challenges of power quality in the face of increasing renewable energy integration and varying load demands.
