Abstract
Abstract: Strong nonlinearity and large fluctuation are the characteristics of wind power generation system. Quickly controlling the output power of wind turbines within the rated range under wind speed random changes is the major problem of wind power system control. Aiming at the pitch control of 5 MW wind turbines, a pitch control scheme for wind power generation systems based on the Wiener model is proposed. On the basis of the special structure in which the linear and nonlinear links of the Wiener model can be separated, the controlled object of a generalized wind power system with linear properties is constructed by calculating the inverse of the nonlinear part, which simplifies the nonlinear pitch control problem of the wind power system to a linear model control. The independent separable signal is used to identify the Wiener model of wind turbines by separate steps, which can accurately predict the output power of the wind turbines. The simulation examples show that the control method can effectively improve the control effect of the pitch system.
