MITIGATION OF POWER QUALITY PROBLEMS USING DYNAMIC VOLTAGE RESTORER (DVR)

A Power quality problem is an occurrence manifested as a nonstandard voltage, c urrent or frequency that results in a failure or a mis - operation of end use equipments. Utility distribution networks, sensitive industrial loads, and critical commercial operations all suffer from various types of outages and service interruptions which c an cost significant financial 1oss per incident based on process down - time, lost production, idle work forces, and other factors.
