摘要
在综述不同类型的风力发电机系统特点的基础上,结合国外风电市场的概况和电网对风电机组的要求,对风电机组类型的发展趋势进行了探讨。按风电机组的控制特点和传动链类型,对不同类型风电机组的原理、优缺点和当前的概况进行介绍,并对永磁同步发电机结构进行了重点分析。其次,对不同类型风力发电系统的经济性和市场应用情况进行了定量比较分析。最后,结合电网对风力发电机组的要求,对并网风力发电系统的发展趋势及其比较标准进行了探讨。
An overview of different wind generator systems and their development was presented in this paper. Firstly, the contemporary wind turbines were classified with respect to both their control features and drive train types, their strengths and weaknesses were described. The promising permanent magnet generator types were also investigated. Then, the quantitative comparison and market penetration of different wind generator systems were presented. Finally, the developing trends of grid-connected wind generator systems and appropriate comparison criteria were discussed based on the grid requirements to the large wind turbine generation systems.
