电力电子技术在风力发电中的应用

Application of Power Electronics Technology in Wind Power

随着经济的快速增长和社会的全面进步,我国的能源供应和环境污染问题越来越突出。开发和利用可再生能源的需求更加迫切。风能作为可再生能源中最重要的组成部分和唯一经济的发电方式,由于其清洁无污染、施工周期短、投资灵活、占地少,具有良好的社会效应和经济效益,已受到世界各国政府的高度重视。随着现代电力电子技术以及变频调速技术的迅速发展,其在风力发电中的应用也更为广泛。重点介绍了电力电子技术在风力发电中的主要应用,包括风力发电系统的分类;双馈风力发电双向变频器的优缺点;风力发电的输送方式等。最后对风力发电的前景进行了展望。

With the developing of economic and improving of society, the energy supply problem and environment pollute problem becomes more and more extrude. So there is more and more impendence need to develop and utilize Renewable Energy. Wind energy is becoming the most important part of renewable energy and the unique economical method of generation power and is being paid more attention by governments all over the world because of its characteristics such as cleaning, short construction time, flexible investment and better economical benefits and social benefits. Along with the rapidly development of modem power electronics and adjustable speed technology, the power electronic technology is widely used in wind generation. The applications are summarized and the prospect of the power electronics used in wind generation is presented.
