摘要
直驱式变速恒频风力发电系统由于其采用低速永磁同步发电机结构,系统无需齿轮箱,具有机械损耗小,运行效率高,维护成本低等优点而受到了越来越多的关注。针对直驱式变速恒频风力发电系统变流器拓扑结构进行研究,对比分析了晶闸管变流器,电压源型逆变器,电流源型逆变器等各种变流器结构,指出了各自的优缺点。
The Direct-driven variable speed constant frequency （VSCF） wind generation system takes low speed PM generator as the generator ,and it has the advantage of no gearbox ,low mechanical loss, high efficiency, low maintenance cost. So it has been paid more an more attention. The topology of the Direct-driven variable speed constant frequency （VSCF） wind generation system is analysed, the SCR converter, voltage resource inverter are compared, current resource inverter, and points out the advantage and disadvantage of each topology.
