摘要

When the wind speed is below the rated value, the generator is controlled to maximize the captured wind energy. According to multi-time scale of wind speed, the nonlinear mechanical model for wind energy conversion system (WECS) is established, and the Linear Parameter Varying (LPV) system model is released. Based on PI control strategy, the LPV gain scheduling control is taken as dynamic compensation technology. Simulation results show that the power coefficient and the tip speed ratio have much better accuracy and robustness in tracing their optimal value after compensation, which result in better dynamic performances.
