Power Quality Improvement in Electrical Distribution System

Abstract

Power quality is a problem that is becoming more prevalent in industry and industrial applications. To maximize energy efficiency and productivity, modern factories use sensitive and sophisticated equipment. Voltage sags and swells in the form of voltage to solve these problems There are several custom power devices in use. DVR or Dynamic voltage restorer is one of many devices, and it is the most powerful and reliable custom power unit. DVRs are usually wired in series between the source voltage and the sensitive load. DVR's key role is to rapidly mitigate voltage sags in the device and restore load voltage to pre-fault levels. This research shows how to model and monitor a DVR using When a three-phase load is connected with the system how the voltage performs with respect to the fault that is applied and how DVR is capable of reducing those faults/sags. load is linked to the network; a proportional and integral (PI) controller is used to alleviate voltage sag swell. The simulation is supported by the result of the simulation Simulink method.
