摘要目前全球发电行业主要以煤为燃料驱动蒸汽轮机发电产生电能。由于人类的大量开采，这种不可再生能源日益紧缺，同时煤的燃烧会对环境造成污染，并且有越来越严重的趋势，已经威胁到了人们的生存和发展。尤其是近年来，我国雾霾现象有加重趋势，将无污染且资源丰富的风能作为发电能源具有十分重要的意义。稀土永磁风力发电系统相比于传统的风力发电系统，具有很多优点，它结构相对于简单，运行可靠，不需要频繁维护，同时这种风力发电系统具有更高的风电转换效率，整体造价也较便宜。综合这些优点，可独立运行的稀土永磁风力发电系统非常适合在我国沿海和西部地区进行推广。86478

本文对风力发电和它的控制技术进行了介绍，同时介绍了小型风力发电系统的构成要素，以及各个部件的工作原理，并且设计了一套独立运行的稀土永磁风力发电系统。另外还设计了一套风机系统用于模拟自然风，作为发电机的原动机。

Abstract In the current years, global power generation industry mainly fire coal to drive steam turbine so as to generate electricity。 Due to extensive exploitation of human beings, this kind of non-renewable energy is increasing scarcity。 Pollution is caused by the burning of coal on the environment, and there is a worsening trend。 It has been a threat to people's survival and development。 Especially in recent years, China's haze phenomenon is increasingly bad。 The non-pollution and rich resources of wind energy can be used to generate electricity。 Compared to traditional wind power generation system, rare earth permanent magnet wind power system has many advantages。 With respect to its structure is simple, reliable, does not require frequent maintenance, such wind power generation system has a higher conversion efficiency of wind power。 The overall cost is also cheaper。 Think about the combination of these advantages, the rare earth permanent magnet wind power generation system that can be run independently is very suitable for promotion in China's coastal and western regions。

In this paper, wind power and its control technology were introduced。 Also, it is introduced that elements of small-scale wind turbine system, as well as works of various components。 Rare earth permanent magnet wind turbine system that can be run independently is designed。 It also designed a fan system for simulating natural wind, as a generator prime mover
