Abstract
In recent years, power quality has become the most prominent issue in the field of electrical engineering. A nonstandard voltage, current, or frequency is the result of a power quality problem. Various forms of outages affect utility distribution networks, sensitive industrial loads, and vital commercial operations, and service disruption can result in considerable financial losses. Voltage sag is one of the primary issues addressed here. Power quality issues can be mitigated thanks to rapid advancements in power electronics technology. This research focuses on issues such as voltage sag and other power quality issues. Many technologies, including STATCOM, tap changing transformers, UPFCs, and DVRs, are available to help with voltage sag issues. The dynamic voltage restorer, which injects both voltage and power into the system, is the most commercially viable method for mitigating voltage sag. The Dynamic Voltage Restorer is a power electronics-based device that can swiftly reduce voltage sag in the system and restore the load voltage to its pre-fault value. This article begins with an overview of important power quality issues for a DVR as well as voltage sag reduction using power electronics controllers. The functioning and components of DVR are then explained. Using the Sinusoidal Pulse Width Modulation (SPWM) method, this thesis proposes using the error signal to regulate the triggering of switches in an inverter. MATLAB SIMULINK was used to model and simulate the proposed DVR.
