摘　　要：化石燃料(煤、油等)排放温室气体,是污染大气环境的主要原因。大量发展可再生能源可保护大气环境、并在社会经济发展中起主要作用。清洁的可再生能源包括:水力、风力、太阳光伏、生物质能、燃料电池(氢能)、海洋能等。风力发电系统,通过风力发电机组将风能转换为电能,技术上较成熟.技术经济性能优越,是近年来发展最快的一种可再生能源的发电技术。其主要优点是:不排放有害气体、无温室效应、可靠、寿命长等,是一种清洁的可再生能源.主要应用于我国风力资源丰富的近海离岸地区和三北地区、无电或缺电地区,通过联网为工业和住宅供电,和其它可再生能源(如太阳光伏发电、微型透平机组等)组成混合分布式电力系统。缺点是:系统建造成本较高.本文简要介绍风力发电技术的历史发展进程、国内外发展概况和发展趋势,风力发电系统的类型、电力电子技术在风力发电系统中的应用等。Fossil fuels are major cause of environmental destruction in pollutions. It has created much needed momentum for renewable energies, such as hydro, wind, solar, geothermal, biomass, fuel cell （hydrogen）, ocean, etc., which are environmentally benign, generated locally, and can play a significant role in developing economy. Wind power, as a fastest growing sustainable energy source, can grow at a rapid pace to meet increasing demands for electricity in a costeffective way. The historical evolution, the state of the art and developing trends and classification of the wind power technologies are presented in this paper. Power electronics playing an important role in the utilization of wind energies are also introduced.
