Performance Analysis of DFIG based Wind Energy Conversion System Using Direct Power Controller

V. Kaarthikeyan | G. Madusudanan

Abstract: In this paper, Direct Power Control (DPC) is introduced for the DFIG based wind energy conversion systems under distorted conditions. DFIG is very sensitive to grid disturbances and it experiences many problems such as distorted stator or rotor current, electromagnetic torque and power oscillations. The fifth and seventh order harmonics under distorted condition are analyzed in this paper. The harmonics level of those harmonics is reduced by using Vector Proportional Integrated Regulator. The steady state and stability consideration of the proposed regulator has been analyzed. With its fast dynamic response, the regulator has full voltage and power control, the smooth real and reactive power output can be achieved. The simulation is done by using MATLAB/SIMULINK software.
