Analysis and design of DVR performance for voltage sag mitigation T. Naveen Kumar

Abstract

This paper deals with terminology and various problems concerning ‘power quality issues’. Voltage sags and swells are the normal activities on the electric power network. These issues can be mitigated with voltage injection procedure utilising custom power device, Dynamic Voltage Restorer (DVR). In this paper we design a Dynamic Voltage Restorer (DVR) which is utilized for power quality growth. Here we advocate two control procedures that are the Proportional integral (PI) Controller and Fuzzy common sense (FL) Controller. Results of each the controllers are assessed to understand which the best power quality solution.
