摘要
人类利用风能已有数千年历史，在蒸汽机发明以前风能曾经作为重要的动力，用于船舶航行、提水引用和灌溉、排水造田、磨面和锯木等。埃及被认为可能是最先利用风能的国家，约在几千年之前，他们就开始用风帆来帮助行船，波斯和中国也很早开始利用风能，主要是使用垂直轴风车。欧洲到中世纪才广泛利用风能，荷兰人发展了水平轴的风车，18世纪荷兰曾利用近万座风车将海堤内的水排干，早出的良田相当于国土面积的三分之一，成了著名的风车之国。在蒸汽机出现之前，风力机械是动力机械的一大支柱，其后随着没、石油、天然气的大规模开采和廉价电力的获得，各种曾经被广泛使用的风力机械，由于成本高，效率低，使用不方便等，无法与蒸汽机、内燃机和电动机等相竞争。风力发电时利用风能来发电，而风力发电机组，试讲风能转化为电能的接卸。风轮是风电机组最主要的部件，由桨叶和轮毂组成。桨叶具有良好的空气动力外形，在气流作用下能产生空气动力使风轮旋转，将风能转换成机械能，再通过齿轮箱增速驱动发电机，将机械能转变成为电能。风电技术进步很快，风电机组高科技含量大机组可靠性高，风电的突出优点是环境效益好，不排放任何有害气体和废弃物。

Abstract
Human use of wind energy for thousands of years, before the invention of the steam engine as the wind was once an important impetus for ship navigation, reference, and for water irrigation, drainage farmland, grinding and sawing wood and so on. Egypt is thought to be the country's first use of wind around for thousands of years before they began to help with the sailing sailing, Persia and China have begun to use wind energy early, mainly vertical axis windmill. Europe to the Middle Ages before widespread use of wind energy, the Dutch developed the horizontal axis windmill, 18th century Dutch windmills have used ten thousand seawall water drained out of the fertile early as the equivalent of one third of the land area, has become State windmill noted. Appeared before the steam engine, wind power is a major pillar of mechanical machinery, and subsequently with no oil, large-scale exploitation of natural gas and cheap electricity available, a variety of mechanical wind had been widely used because of the high cost and low efficiency inconvenient to use, etc., can not compete with, such as the steam engine, the internal combustion engine and electric motor. Wind power generation using wind to generate electricity, while wind turbine, wind energy into electricity lecture unloading. Wind turbine wind turbine is the most important part, the blades and hub components. Good aerodynamic blade shape, to produce in the gas flow so that the aerodynamic wind turbine is rotated to convert wind energy into mechanical energy, and then drives a generator through a gearbox growth, the mechanical energy into electrical energy. Wind power technology advances quickly, high reliability, large units of high-tech wind turbines, highlighting the advantages of the environmental benefits of wind power is good, does not emit any harmful gases and waste.
