POWER QUALITY IMPROVEMENT FOR INDUSTRIAL CONNECTED POWER SYSTEM

Abstract

Power quality is a critical aspect of electrical supply systems, especially in industrial settings where the operation of sensitive equipment and manufacturing processes heavily relies on stable and high-quality electrical power. This paper presents an overview of the challenges associated with power quality in industrial loads and explores various solutions aimed at improving it. Industrial loads are prone to various power quality issues, including voltage sags, harmonic distortions, voltage fluctuations, and transient disturbances. These issues can lead to production downtime, equipment damage, and increased operational costs. To address these challenges, a multifaceted approach is required. This paper discusses several strategies for power quality improvement in industrial loads. These strategies encompass both proactive and reactive measures. Proactive measures include proper equipment selection, load balancing, and the use of power factor correction devices to reduce harmonic distortions and improve overall system efficiency. Reactive measures involve the installation of protective devices such as surge suppressors and voltage regulators to mitigate the impact of voltage sags and transient events. Furthermore, the paper explores the role of advanced technologies such as Dynamic Voltage Restorers (DVRs) in rapidly correcting voltage sags and enhancing power quality. It also emphasizes the significance of real-time monitoring and data analytics for identifying power quality issues and optimizing load management.
