摘要：
In this paper, the authors investigate the evaluation of FOC, DTC and DPC strategies applied to a Variable Speed Wind System (VSWS) based on a DFIG. A comparative analysis of the three controls is performed, in healthy and faulty grid conditions: balanced and unbalanced small voltage dips and grid frequency disturbances. The study emphasizes the limitations introduced by the approximations usually assumed to simplify the design of these control strategies. The influence of these hypotheses is analysed through of the specific wind turbine quantities like generated active and reactive power, electromagnetic torque and currents. Simulation results are provided to illustrate the effectiveness of the approach. Copyright (C) 2009 Praise Worthy Prize - All rights reserved.
