A NEW MINIMAL ENERGY INJECTION CONTROL STRATEGY FOR DYNAMIC VOLTAGE RESTORER USING FUZZY LOGIC CONTROLLER

P.PIRAMANATHAN, M.RAMASAMY

A novel Dynamic voltage restorer (DVR) with fuzzy controller installed between the supply and sensitive load to protect sensitive devices in voltage disturbances. DVR should inject voltage and active power from DVR to distribution system during voltage disturbances. Inject voltage limit due to limitation of DC energy storage so necessary the minimize energy injection from DVR. In this paper new control method for DVR is proposed by combing with fuzzy logic. The proposed fuzzy control DVR method is restoration technique is regiment to injection minimum energy for a given apparent power of DVR.
