- Abstract
The pitch control strategy of the wind generator set in the paper applies power feedback closed loop control to implement that variable-speed constant-frequency wind turbine regulates constant power removal by adjusting pitch angle under the condition above the rated speed. The present output power of the generator is measured by power acquisition, and the power deviation is calculated out by comparing with the given power (the rated power of the generator). And the power variance is the input of the power controller. The controller sends the order of blade referring to pitch angle according to power variance, and the pitch-regulated mechanism adjusts the blade of the fan according to the pitch angle. The actual wind power generation system is a multivariable, nonlinear, strong coupling and time-varying complicated system, and it is difficult to establish the accurate mathematical model. So traditional PID algorithm is difficult to be qualified for the power controller of large high-performance wind generator set. The research indicates that parameter self-tuning PID controller based on fuzzy logic not only can solve the problem of linear control, but also adapts to nonlinear system [31]. Based on the basic rues of pitch control, the paper proposes a design scheme of fuzzy PID power controller, and simulates the wind generator set of fuzzy PID power controller.
