Application of proportional-integral and disturbance accommodating control to variable speed variable-pitch horizontal axis wind turbines
Modern wind turbines are controlled in varying wind speed by blade pitching for power control. To satisfy the requirement of large driving forces and torques, fast response and high stiffness, hydraulic technology is usually used in the variable-pitch mechanism. The model of the hydraulic variable-pitch mechanism (HVPM) is simplified by a first-order inertia system in most literature. This simplified representation neglects the actual characteristics of the HVPM, and it is not precise and reasonable. Therefore, HVPM modelling is implemented and analyzed in this paper. Simulation results show that consequently the variable-speed wind turbine performs well at above-rated wind speeds.
