风力发电发展简史及各类型风力机比较概述

Summarize of the history of generating power by wind and comparison of some kinds of wind turbine

当今对风能的利用,主要是用来发电,通过对风能发电历史的回顾和对水平轴和垂直轴风力发电机的比较,使人们对垂直轴风力发电机有了更加广泛的认识。

By the end of 1990s, wind energy has gotten many countries＇ attention as one of the most important sustainable and environment friendly energy resources. The power of the wind has been utilized for at least 3000 years. In the modem time, we mostly use the wind power to generate electrical energy. The horizontal-axis wind turbine approach currently dominates the wind turbine applications. Researchers of many countries pay more and more attention to the vertical - axis wind turbine for its super excellent aerodynamic performance. So it arouses an interest in making a comparative study between HAWTs and VAWTs. This paper introduces the above two turbines and makes a comparative study about them, also reviews the historical development of the wind power electricity generation.
