| [摘 要]：科学与技术的飞速发展，带来了能源利用方面的革新。规模化的可再生能源（如风能、波浪能、潮汐能等）的使用，给传统电力系统，比如使用煤炭发电的系统，带来了巨大的冲击和深远的影响。能源利用形式从传统的机械能转换为电能，是工业革命时期的一个重要里程碑。37449 风能，是大自然赐予地球的、一种极其丰富的可再生能源。由于其较为清洁，储量丰富，分布广泛以及容易获取的优势，许多国家已经十分重视它。近年来，随着世界能源的极度匮乏，以及人类对于环保的要求，各国专家正在全力研究替代天然气，煤炭等能源的可再生的环保的绿色能源，所以，风力发电在世界各国得到了广泛有效的利用。不管是在发展规模还是在发展水平上，都有了很大的提高。风力发电在电力能源中所占比重越来越大，人们已经不能忽视风力发电系统给电网带来的影响。 本课题着重通过对风力发电机发电系统的设计，研究小型风力发电机组在家庭实际生活中的应用，从而解决偏远地区用电难的问题。 [毕业论文关键词]：风力发电机，AC-DC-AC，蓄电池 The design of small wind turbines’ system for households Abstract: The rapid development of science and technology has brought reformation about the utilization of energy. The massive renewable energy (wind energy, wave energy, tidal energy , etc.) is being applied, which has great and far-reaching impacts on traditional electrical systems, such as the system which uses coals to generate electricity. The form of energy’s utilization, which transforms traditional mechanical energy into electrical energy, is a significant milestone during the period of the industrial revolution. Wind energy, which nature gives earth, is a kind of inexhaustible and renewable energy. It has drawn more and more attention due to its advantages that it is relatively clean, plentiful, widely distributed, and easily obtained. In recent years, with the extremely shortage of energy in the world and people’s desire to environmental protection, the experts are trying to find renewable and environmentally green energy which can replace gas and coal. Thus, wind-generated electricity has been utilized worldwide. It has made great progress both in size and level of development. Wind-generated electricity has had a larger and larger proportion in electric energy. It can’t be ignored that the system of wind-generated electricity has great influence over power grid. The project mainly studies the application of small wind turbines’ system for household by designing the small wind turbines’ system, to address the problem that people in poor areas can hardly use electricity.
