Abstract :
Based on the wind-turbine characteristics, a method of tracking the maximum wind energy using fuzzy logic principles, without the wind velocity measurement is proposed, which is independent of the turbine parameters and air density. The generator is operated in the indirect speed control mode with the speed reference being dynamically modified by fuzzy logic system in accordance with the magnitude and direction of active power changing. By analyzing the mathematical model of a doubly-fed induction generator (DIFG) and the filed-oriented vector transformation control scheme, the whole variable-speed constant-frequency (VSCF) wind-power generation is formed. The simulation results validate the correctness of the proposed control strategy.
