中文摘要：
针对大型风力机桨叶承受载荷不均匀的问题,在研究传统的统一变桨距控制策略的基础上,提出了一种基于最小化多变量的优化独立变桨距控制策略。以将风力机桨叶桨距角与发电机转速为控制变量,同时实现多变量最小化,再结合独立变桨距控制,利用bladed软件对该控制策略进行仿真。通过仿真结果验证可知,在风力发电机组获得最大功率情况下,相比传统的变桨距控制策略,该控制策略具有很好的鲁棒性和更好的减载效果,弥补了统一变桨距控制的不足,完全符合大型风力发电机组对桨叶载荷控制的目的。
英文摘要：
For large-scale wind turbine blades load under uneven, based on the research of traditional pitch control strategy, a kind of optimization was put forward to minimize the multi-variable on account of the independent variable pitch control strategy. The blade pitch angle and generator speed were taken as control variables. At the same time the multi-variable minimal optimization was realized. Combined with the independent variable pitch control, the simulation with bladed software was simulated. Simulation results of the presented control strategy shows that compares with the traditional method of uniform pitch control, in the wind turbine maximum power condition,the control strategy has the better robustness and load shedding effect,which make up for the deficiency of the uniform pitch control,so it is very suitable for large-scale wind turbine.
