论文中文摘要:
风能和太阳能、水能一样,都属于绿色能源的范畴,它们具有无污染、储量丰富和使用范围广等优点。但是,相对于其他种类绿色能源来说,风能又具有较高的随机性和不确定性,在使用风力发电系统发电时,由于风能的不确定性,会使得发电的质量受到较大影响,如果负载也是时变的,则整个发电系统的控制难度就会更大,基于以上原因,使得风能的利用难度要大于其他种类绿色能源的利用。 论文第一章综述了风力发电及其控制技术以及风力发电在我国的发展情况;在第二章中,主要论述了独立式风力发电系统的基本组成和各部分的作用及运行原理;论文第三章,结合对风力发电最大功率控制技术的分析和研究,详细论述了风力发电机的最佳运行原理。从风力机和发电机两个方面对风力发电最大功率点跟踪技术分别做了分析和研究,并对利用Boost电路实现风力机最大功率点跟踪进行了原理上的分析和推导;最后还提出了一种新型风力发电机模型;第四章中,作者对参与研发的小型风力发电机控制系统做了较为详细的介绍。从系统的总体设计到具体软件、硬件电路及系统其他各组成部分的设计,都给出了详细说明和介绍。第五章对全文的工作做了总结,列出了本文所取得的成果,同时,作者还针对小型风力发电系统中现存的某些问题,阐述了自己的观点和设想。
论文外文摘要:
The Wind power, Solar energy and Hydropower are all called Green Energies. They have the advantages of non-pollution, abundant reserves and could be used widely. But, the wind power has more randomicity and uncertainty compared with other kinds of Green Energies. The quality of power, which is generated by the wind power generators, will be affected greatly due to the randomicity, when the wind power generation system is working. And, if the load changes momentarily, it will be more difficult to control the whole generation system, so, we could conclude that it’s harder to make use of the wind power than the other two kinds of Green Energies. An overall and thorough study on the Stand-alone small scale wind power generating systems is given in this paper. The descriptions of the control technology of the wind power generating system and the introductions of the development situations of the wind power generation system in China are given in the chapter one. The chapter two discusses the composition and operation principle and the functions of each part of the stand-alone small scale wind power generating systems. In the chapter three, the optimal operation principle of the wind power generator is described. The technology of Maximum Power Point Tracking (MPPT) is studied from the two sides of the Wind-turbine and the Generator. A theory of Wind Power MPPT, which is based on the Boost Circuitry, is deduced in paper. And at last, a new-model of the wind power generator is proposed. The detailed introduction of the controller, which was designed by author, is given in the chapter four, including the general design, the hardware circuits and the code implementing. The last chapter summarizes the research results in this paper and the author’s opinions on the small scare wind power generating system. Key words :Stand-alone Wind Power System,MPPT,Boost Circuitry,Horizontal Axis,Vertical Axis
