基于方位角和载荷联合反馈的独立变桨距控制策略研究
Study of Individual Pitch Control Based on Azimuth Angle and Load Feedback
摘要
Abstract
Considering the periodic load fluctuations of wind turbine caused by wind shear and tower shadow, individual pitch control was studied in this paper. Based on blade element momentum (BEM) theory, the blade aerodynamic characteristic was modeled on Matlab/Simulink platform and calculation results were compared with the simulation results on GH Bladed software. The individual pitch control based on azimuth angle and load feedback was proposed in this paper. With azimuth angle feedback, the dynamic weight coefficient was set and the pitch angle of each blade was periodically adjusted. On this basis, the blade root flapwise load PID controller was superimposed to provide the fine tune value and correct the pitch angle of each blade. Then the proposed individual pitch control strategy was verified on Matlab/Simulink and GH Bladed platform and simulation results show that it can significantly alleviate both the periodic and random blade flapwise load fluctuations, which means the strategy holds good potential to reduce rotor unbalance loads and mitigate fatigue loads of wind turbine.关键词
