Synergetic control theory scheme for asynchronous generator based dual-rotor wind power
Habib Benbouhenni
Abstract
This paper presents a new direct active and reactive powers command (DARPC) method for an asynchronous generator (ASG) based dual-rotor wind energy (DRWE) system. Switching vectors for rotor side converter were selected from the modified neural space vector pulse width modulation (MNSVPWM) using the estimated rotor flux position and the errors of the active and reactive power. Using a proportional-integral controller may cause undesired stator current and power oscillation. In this work, the reduced oscillations of active and reactive powers with the application of the synergetic control theory (SYC) will be presented. Then a new DARPC strategy will be proposed. The principle of the schematic and the disadvantages or advantages of the designed technique are proposed. Simulation results of a 1.5 MW ASG system demonstrate the performances, robustness, and effectiveness of the designed technique during variations of ASG parameters, and reactive and active powers.
