大型风力发电机的发展新动向

New Trends of the Development of Large-scale Wind Power Generator

风力发电占总发电量的比重不断提高,风力发电机的使用越来越广.随着大型发电机用各种材料性能的不断提高和改善,很多以前无法实现的电机设计理念得以变成现实.本文简述了目前占主导地位的常规永磁直驱和双馈风力发电机的优缺点;介绍了近期涌现的新型风力发电机:高压风力发电机,液压风力发电机,超导风力发电机,海上用风力发电机,无刷双馈风力发电机等,对于其原理和特点进行了说明;最后对大型风力发电机今后的发展方向进行了展望.

The proportion of wind power electricity rise in all electric quantity, the use of wind turbines generator is more and more widely. With the constant improvement of variety material performance and improvement that used at large generator, the design concept of the generator that previously could not realized be able to become reality. This paper introduces advantages and disadvantages of current dominant traditional permanent magnet direct drive and doubly-fed generator. And introduces recent emergence new wind turbines, high-voltage wind generators, hydraulic turbines, superconducting wind turbines, offshore wind power generator, etc., its principle and characteristics are introduced. Finally for the development of wind turbine generator in the future was prospected.
