Simulation of Stator Oriented Vector Controlled Doubly-Fed Induction Generator for Harnessing Wind Energy Effectively

Abstract

Wind energy plays an increasingly important role in the world because it is friendly to the environment and limitless. During the last decades, the concept of a variable-speed wind turbine (WT) has been receiving increasing attention due to the fact that it is more controllable, efficient, and has good power quality. In order to most effectively utilize the wind energy and improve the efficiency of wind generation system an optimum control strategy of doubly-fed induction generators (DFIG) is proposed. This paper presents a stator flux oriented vector control strategy for a 2MW/690V doubly fed induction generator (DFIG)-based wind energy generation system to control the rotor side converter to control the active and reactive power and grid side converter control to maintain dc link voltage constant.
