【摘要】：风力发电依靠着其独有的特征,如:环保绿色、性价比高、开发简单、资源丰富等先天的优势受到了全世界范围的广泛的应用开发和重视,毫无疑问的成为世界上最值得开发利用的可再生能源之一。从目前所面临的环境污染问题和能源使用率低的问题来看,将来所要面临的问题会日趋严峻,这更加激起了全世界范围内各个国家之间的竞相大力发展的发展可再生能源的热情,尤其是在风电技术上要不断的推陈出新的目标和决心。最近的几年来,我国的风力发电产业得到了蓬勃发展,装机容量连续几年翻倍,提高风力发电的的转换效率,最大限度的将风能转化为电能,其中最重要的环节就是风电并网技术的研究,与其他形式发电类型的水电厂、火电厂的差别在于,由于风能具有不确定性的原因导致了风电的输出功率波动十分明显,在大规模的风电并网中会对电网产生不同程度、不同范围、不同规模等的一系列影响,尤其是在对电网的频率与电网的稳定性等的影响。因此对风电系统的并网操作进行仔细钻研与探讨,并且采取合理的措施保证并网之后电网能更完全稳定的运行有十分重要的意义,风电并网之后,对于风电数据的实时数据(例如风速、发电量等)获取与数据呈现,对风电的研究、维护和发展有着十分深远和重要的意义。论文主要从以下的几方面进行了分析设计:对目前市面上应用比较广泛的主流风力发电系统进行了论述与分析,对风力模型的分析与设计的基础上设计了新型的具有主动变桨距功能的风力发电设备,然后对它的组成及其工作原理上进行了阐述,然后对它机械性能进行了可靠性分析,然后对电路部分进行了设计与SI MULINK仿真并对仿真的结果进行了分析,最后搭建了一个可以实时获取与观察风电数据变化的WEB系统,对未来风力发电技术的不断推陈出新尽一点微薄之力。
[Abstract]:Wind power generation relies on its unique characteristics, such as: environmental protection, green, cost-effective, simple development, rich resources and other innate advantages have been widely used and developed all over the world. Undoubtedly, it has become one of the most valuable renewable energy sources in the world. From the point of view of the current environmental pollution problems and the low energy use rate, the problems that will be faced in the future will become increasingly serious. This has aroused the enthusiasm of various countries all over the world for the development of renewable energy, especially in the wind power technology to constantly promote new goals and determination. In recent years, China's wind power generation industry has been booming, its installed capacity has doubled for several consecutive years, and the conversion efficiency of wind power generation has been improved, so as to maximize the conversion of wind energy into electric energy. One of the most important links is the research of wind power grid-connected technology. Compared with other types of hydropower plants, the difference between thermal power plants and wind power plants is that due to the uncertainty of wind power, the output power fluctuation of wind power is very obvious. In the large-scale wind power grid connection, there will be a series of effects on the grid, such as different degree, different scope and different scale, especially on the frequency and stability of the grid. Therefore, it is of great significance to carefully study and discuss the grid-connected operation of the wind power system, and take reasonable measures to ensure that the grid can operate more fully and stably after the grid connection. After the wind power grid is connected to the grid, it is of great significance. The real-time data acquisition and presentation of wind power data (such as wind speed, power generation, etc.) is of great significance to the research, maintenance and development of wind power. This paper mainly analyzes and designs the following aspects: discussing and analyzing the mainstream wind power generation system, which is widely used in the market at present. Based on the analysis and design of wind power model, a new type of wind power generating equipment with active pitch variation is designed. Then its composition and working principle are described, and then the reliability analysis of its mechanical performance is carried out. Then the circuit is designed and simulated with SI MULINK, and the simulation results are analyzed. Finally, a WEB system is built, which can acquire and observe the change of wind power data in real time. To the future wind power generation technology of the continuous introduction of new and do a little bit of force.
