Abstract

This paper presents the results of an investigation into several direct power control (DPC) strategies for the rotor side converter (RSC) of a doubly fed induction generator (DFIG) based wind energy generation system. The schemes investigated DPC of 2-level hysteresis, DPC of 3-level hysteresis and DPC using Discrete Space Vector Modulation (DSVM), with a 5-level hysteresis. The results of Matlab-Simulink simulations and a comparison between the control schemes are presented, regarding variations of active and reactive power, machine parameters, and wind speed.
