Abstract :
Variable pitch control technology is one of the key technology of wind power generation technology. This paper has studied the pitch control system of wind turbine and the variable pitch power control strategy for wind turbine. Based on the control system and control strategy, Hydraulic variable pitch control system model is established, and build a variable pitch wind turbine system. Then, it has been design an improved PID controller for variable pitch control system. The simulation analysis has carried using Matlab/Simulink simulation software for opening and closing oars two process to carry, the result shows that the improved PID controller of hydraulic variable pitch control system has good speed and accuracy.
