风能作为一种可再生能源越来越受到世界各国政府的重视。与此同时，对风力发电技术和装备的研究开发也日益成为科技领域和企业界关注的热点课题项目之一。

风能是一种清洁并且可再生的能源，利用风能发电能够大量减少其它发电方式对环境的污染。风力发电机的原理是：一定速度前进的风吹在静止的风力机叶片上做功并驱动发电机发电，先通过叶轮将风能转变成机械能，在由发电机将机械能转变成电能。

本文设计了一台功率为1500千瓦的风力发电机，其为水平轴风力发电机，由风轮、发电机、偏航装置、控制系统、塔架等部件组成。对其叶片，行星齿轮增速器，塔架等进行了详细的方案选择及设计计算。

关键词：风力发电；水平轴风力机；叶片；增速器。

Abstract

Wind energy, as a kind of renewable energy, is paid attention to by governments all around the world. The wind power technology and its equipment research become a hot spot topic for technical circles and enterprise.

Wind energy is a clean and renewable energy sources, The use of wind energy to power can reduce a large number of environmental pollution compare with other ways. The principle of wind turbine is: A certain wind speed blowing to the stationary blades of wind turbine-driven generators work and driving generator to power, through the impeller into the wind mechanical energy, then to electrical energy by the generator.

In this paper, a power of 1500 KW wind turbine is designed and its horizontal axis wind turbine, Composed by the impeller, generator, yaw devices, control systems, towers and other components. Carry out a detailed design calculations of  its leaves, the planetary gear speed increaser, tower, etc.

Keyword: wind power; horizontal axis wind turbine; leaves;speed increaser.
