摘要
在各种可再生能源利用中,风能是使用最为广泛和发展最快的可再生能源之一,是近期内最具有大规模开发利用前景的可再生资源。通过对风力发电产业现状进行梳理、归纳和分析,总结了风电机组未来发展趋势,并对风电机组风轮气动分析、载荷计算与分析、结构动力学与控制、能量流传递与调控和变桨距系统等研究现状和面临的问题进行了分析。指出风电机组是涉及多学科理论的复杂非线性系统,包含多物理场和多物理过程,在进一步深入研究过程中,应充分运用多学科知识,采用系统科学的思想方法才能获得全面深入的研究结果。
In various renewable energy sources,wind energy is one of the fastest-growing energy sources worldwide and has a good prospect of development and utilization.The present situation of wind turbines industries was outlined and analyzed herein.The development tendency of wind turbines was summarized;the research situations and problems were analyzed,including aerodynamic analysis on wind rotors,analysis and calculation of loads,structure dynamics and control,energy transfer and control and pitch system.Finally,it is pointed out that since the wind turbine is sophisticated nonlinear system related to theory of multi-disciplines,involving multi-physical coupling field and multi-physical process,the thinking method of system science should be adopted in the future research based on multi-discipline knowledge.
