摘　　要：在新能源战略形势下,针对传统风力发电机组转化率低的问题,提出一种新型风力发电机组装置,并对其发电特性进行研究。该结构突破传统风力发电机组的普遍结构,改用铜质叶片,并在其旋转后端加设永磁体装置,利用电磁感应原理达到二次生电的目的,并建立该环节的数学建模,同时结合Maxwell软件对其所产生的磁场大小进行测定,计算新型风力发电机组的二次发电功率。通过与传统发电机组进行比较可知:在5 m/s的低风速情况下,新型风力发电机组比传统风力发电机组的发电功率提高了近45.9%;而在12.5 m/s的风速下,也比传统风力发电结构的发电功率提高了近8.41%。Under the situation of new energy strategy in China,aiming at the problem of low conversion rate of traditional wind turbine,a new type of wind turbine device was proposed,and its power generation characteristics were studied.Breaking through the common structure of traditional wind turbine,copper blade was used,and permanent magnet device was added at its rotating rear end.The purpose of secondary electricity was achieved by using the principle of electromagnetic induction,and the mathematical modeling of this link was established.At the same time,the magnetic field generated by the new wind turbine was measured by combining with Maxwell software,and the secondary power of the new wind turbine was calculated.Through the comparison with the traditional wind turbine,it can be seen that:in the case of 5 m/s low wind speed,power generation of the new wind turbine is nearly 45.9%higher than that of the traditional wind turbine while also nearly 8.41%in the case of 12.5 m/s.
