摘要在这个社会上，不可再生能源每天都在被消耗。而这些能源一旦被没了就再也不能为我们提供可观的能量供给。其不可再生的本质让我们在能源利用上，觉得有点受到约束，所以我们需要最快的找到可以替代它的能源。这样就可以平缓目前能源供给的需求，而风能相对来说是一种比较干净的，而且能量充足的一种能源。它自身有很多的优点。所以在人类的发展中起到很好的作用。
- 上一篇：大规模电动汽车并网系统电压稳定性研究
- 下一篇：双馈型风电场并网系统低电压穿越能力的研究
在我们文章的一开头，我们就在介绍风能的优势，和依靠它来发电的历史以及目前给人们带来的好处。第二章，文章详细的指出了什么叫做电压的稳定性，我们改如何去改善它，让它处于这个稳定的状态。第三章，开始介绍电压穿越能力的基本概念，分析方法，以及研究穿越能力的内在意义。第四章就风电场中直驱永磁同步发电机做了基本的介绍，详细的介绍了它的原理和特点，并且对它的优点做了一个详细的介绍，同时也分析出了它的应用现状及以后发展趋势。其中二，三，四章主要就是介绍了本文研究所需的基本概念以及定义，为第五章所要讲的仿真研究，打好了基础。到了第五章，也就是本文的的重心部分了，之前的论述都是为了给这一章做铺垫。一开始的时候。我们先对PSAT工具箱大致的进行一个了解，主要是用来建模的，后面会提及。接下来要做的就是用PSAT做一个风电场的建模，进而选择一个参数，分析电力系统电压稳定和故障极限切除时间。最后一步就是开始进行短路模拟，分析。46507

Abstract
In this society, non renewable sources of energy are consumed every day. These energy sources, once they are gone, can no longer provide us with a significant energy supply. Its non renewable nature makes us feel a little constrained in our energy use, so we need to find the energy that can replace it quickly. This will be able to smooth the current demand for energy supply, while the wind is relatively clean, and a sufficient energy. It has a lot of advantages. So in the development of human beings to play a very good role.
At the beginning of our article, we introduce the advantages of wind energy, and rely on it to power generation history and the benefits of the present. The second chapter, the article details what is called the stability of the voltage, we change how to improve it, so that it is in the stable state. In the third chapter, the basic concepts, analytical methods, and the intrinsic significance of the research on the ability of the crossing ability are introduced. The fourth chapter is wind farm Zhongzhi drive synchronous generators do basic introduction, detailed introduces the principle and characteristics, and a detailed introduction to the advantages of it, and analyzed the application status and future development trends.Among them, two, three, four chapter mainly introduces the basic concept and definition of this paper, which is based on the simulation of the fifth chapter. In the fifth chapter, which is the focus of this paper, the previous discussion is to give this chapter to pave the way. At the beginning. First, we have a general understanding of the PSAT toolbox, mainly used to model, will be mentioned in the back. The next thing to do is to use PSAT to do a modeling of the wind farm, and then select a parameter, analysis of power system voltage stability and the failure of the limit of time. The last step is to start short circuit simulation, analysis.
Key words: sea breeze electric field grid connected system； low voltage ride through；voltage stability；PSAT； direct drive permanent magnet synchronous generator
