摘要
以直驱和齿轮箱驱动的风力永磁同步发电机系统为研究对象,采用实数编码遗传算法对系统进行优化设计,并用有限元方法对优化结果进行验证。通过对不同驱动链结构以及不同功率等级风力永磁同步发电机系统的成本、年发电量、损耗及效率等特性进行优化设计与分析,结果表明:直驱式风力永磁同步发电机系统的年发电量最高,一级齿轮箱驱动的风力永磁同步发电机系统经济性最好,三级齿轮箱驱动的风力永磁同步发电机系统没有明显优势。
The PMSG systems were optimized by the real-coded genetic algorithm and the results were validated by the fi- nite element method. 3 kinds of typical drive trains and 5 different power ratings were considered to get the tendency, and the cost, annual enegy production （AEP）, loss and efficiency of the different PMSG systems were studied respective- ly. The results showed that the direct-drive PMSG （DDPMSG） has the highest energy yield, but it is more expensive than the PMSGs with 1-stage gearbox （G1PMSG） and the PMSG with 3-stage gearbox （G3PMSG） with the increase of power ratings. G1PMSG seems more attractive in terms of cost-effective. G3PMSG has no significant advantage compared with the others. The conclusions provide the valuable references for the design optimization and type selection of the PMSG systems for the wind turbines.
