摘　　要：根据国内外大型风力发电机组制造厂商的产品及其技术特点,对主流兆瓦级风机的主传动系统结构特点进行了深入剖析。同时,从发电量、度电成本、可靠性、可维护性和大容量拓展5个方面,对主传动系统的性能和可靠性进行了对比研究,为主传动链形式的选择提供了依据。最后,介绍了近年来风电领域的新技术、新产品的开发及其在风机上的应用情况,为风机主传动链的改良以及环境适应性提出了合理化建议。According to products and technical characteristics of multiple megawatt wind turbines at home and abroad, this paper analyzes the characteristics of main drive train system structures on the mainstream of MW-level wind turbines. Moreover, from the aspects of generating capacity, cost of electricity, reliability, maintainability and capacity expansion, the main drive train performance and reliability were studied, which provides a basis for the choice of main transmission chains. Finally, this paper introduces the development of new technology and new productes of wind power and wind turbine application in recent years, and proposes some reasonable suggestions for wind turbine main drive chain improvement and environmental adaptability.
