Abstract

In this method attempts to have the effect of studying electrical devices for voltage drop. Modern industrial methods are based on a large number of electronic devices such as programmable logic controllers and adjustable speed drivers. Unfortunately, electronics are sensitive to interference, and as a result, industrial loads cause less resistance to power quality problems such as voltage sag, voltage swells and harmonics. Voltage sag are an important measure of the power quality problem, and Dynamic Voltage Restorers (DVRs) are known to mitigate their usefulness. Dynamic Voltage Restorers (DVR) have become popular as a cost effective solution to protect sensitive loads from voltage sag and swelling. A control system that uses a phase locked ring. The phase locked ring is used to maintain a continuously synchronized load voltage and monitor the source voltage. The results show that the proposed method improves the performance of the DVR.
