高效风轮发电机新技术研究进展

Research on new technologies of high efficient wind generator

阐述了当前世界风能利用的发展态势,分析了中国风能开发面临的机遇与挑战的形势和未来的发展方向.指出了目前世界上流行的传统的塔架式三叶片风电机存在着风能转换效率不高、轻风难启动、烈风须停机、时间利用效率不高等缺点.探讨了进一步提高风电机双向效率的相向旋转式、风筒式、全永磁悬浮轴承式风轮机和变浆距双馈直驱永磁式风电机,以及惯性飞轮储电等国内外多项新技术的研究进展与研发范例.提供启发,以促进风能利用和风电技术的健康发展.

Development situations in recent years,as well as the good opportunity and severe challenge to china＇s wind energy development and utilization are reviewed in this paper.It＇s pointed out that the traditional tower type wind generators with three vanes popular in the world have disadvantages such as low efficiency of wind energy conversion,not starting in light wind,stopping in strong wind,low efficiency of time utilization.New research progresses and development examples of new technology,such as rotary type,wind drum type,permanent suspension bearing type wind turbines,variable pulp distance double feeder direct-drive permanent magnet wind generators and inertial flywheel power storage are discussed.It helps to promote the wind＇s utilization and the technology development.
