Abstract: In order to solve the uneven dynamic load problem of large-capacity wind turbines, the Linear Quadratic Gaussian (LQG) scheme is proposed, which can calculate and compare the loads borne by main components of wind turbine under different control modes based on the wind turbine model and LQG controller through co-simulation of SIMPACK and Simulink software. The simulation result shows that, compared with the collect pitch control strategy, the independent pitch control strategy is superior in stabilizing the output power and load fluctuation. Compared with the PI collect pitch control, the LQG independent pitch control can better reduce the fatigue load of main components of wind turbine.

Key words: wind turbine, LQG, independent pitch control, fatigue load
