【摘要】 随着能源问题和环境问题的日益突出,作为一种清洁的可再生能源,风力发电越来越受到人们的重视,与此同时,风力发电技术也成为各国学者竞相研究的热点。开关磁阻电机是电机技术与现代电力电子技术、微机控制技术相结合的产物,本文主要围绕开关磁阻发电机(SwitchedReluctanceGenerator,简称SRG)在风力发电领域中的应用,展开了较为全面的理论分析和仿真检验。首先,本文结合大量的文献资料,全面总结和分析了当前风力发电及相关技术的发展现状和前景,提出了开关磁阻电机适合于风力发电的几大优势,进一步明确了开发开关磁阻风力发电系统的意义。其次,从全新的角度对开关磁阻发电机的运行和控制机理进行了阐述。讨论了风力发电系统的几种控制方案及其发电的过程。最后,建立了开关磁阻发电机的非线性电感模型,并利用MATLAB软件建立了开关磁阻发电机的非线性数学模型,并分别结合PID控制器、公式型模糊PID控制器进行了发电系统的仿真实验。获得了一些较为符合实际的理论结果。更多还原

【Abstract】 Now, energy sources consume increasing daily and environment empoison being serious gradually, wind power, as renewable, no pollution energy source, is paid great attention by more and more countries. The technologies also become research hotspot of many countries.As the representative of modern electrical machines, switched reluctance machine combines the electrical machine theories with the modern power electronics technique and the advanced microprocessor control technique. This paper mainly focuses on the application of switched reluctance generator in wind generation, and has done some further theoretic research as well as simulation research.Firstly, this paper summarized and analyzed the present and the prospective of wind generator and relative techniques based on a large number of referenced materials, presented the several advantages of SRG wind generator system, further development the significance of developing this kind of system clear.Secondly, this paper describes the operation and control principle of SRG form the new perspective and discusses the control method and the process of power generation.Finally, a mathematical model of SRG nonlinear inductance was produced. This paper produces the mathematical model with MATLAB and PID controllers、the formula-fuzzy PID controllers are used for the power system simulation. This paper obtains some results conforming to the reality.更多还原
