新型风电机组发展趋势

The Half-Drive is a New Developed Direction for Large Wind Power

本文概述了当前国外大型风电机组的发展方向,通过对大于5MW以上的大型风电机组研究,分别对永磁直驱、双馈齿轮箱、双馈半驱及凸极同步机进行分析比较。分析指出,当前国际上,研究方向是研制10MW及20MW大型风电机组,半驱是一个新方向。本文提出基于新型双馈变速恒频凸极同步电机,是当前研制10MW及20MW大型风电机组的重要途径,新型半驱风电机组将是大型风电机发展的新方向。

This paper summarizes currently the developed uptrend for large wind power. Base on analysis and research of large wind power with power more than 5MW, this paper separately introduces the large direct drive permanent-magnet wind generators, the doubly-fed induction generators with gearbox, the doubly-fed induction generators with signle gearbox(half-drive) and the salient pole synchronous generaotors and be compared with each other. Up-do-date Its point out that the exposure is the research large wind powe...
