风电机组气动载荷控制策略
Control strategy of aerodynamic load for wind turbine
摘要
Abstract
Aiming at the problem that under the influence of wind shear effect, the blade with a large size will aggravate the imbalanced aerodynamic load suffered by the wind rotor, a combined control strategy of both synchronous variable pitch based on modified discrete fuzzy control and individual variable pitch based on blade azimuth angle weight coefficient assignment was proposed. The stability of wind turbine output power was realized with the active variable pitch control, and meanwhile the axial aerodynamic load suffered by the wind rotor reduced. The simulation results show that when the wind turbine runs at the rated working range, the combined control strategy can not only stabilize the fluctuation of output power near the rated power of wind turbine, but also effectively suppress its axial aerodynamic load. Therefore, the effectiveness of the proposed control strategy is directly proved.关键词
