CONTROL OF PMSG BASED WIND ENERGY CONVERSION SYSTEM WITH THREE-LEVEL BOOST AND NPC CONVERTERS

Abstract

In this paper, a new medium voltage (MV) PMSG based variable speed wind Energy Conversion System (VSWECS) controlled by three level boost(TLB) and Five level Neutral point clamped(NPC) converter is presented to improve the performance. The dc-link control strategy for tracking the maximum power and maintaining constant Dc-link voltage will be performed by TLB. The simulation results for 3MW/3000V/50Hz non salient pole PMSG wind energy system are presented to validate the topology and control scheme
