永磁/笼障混合转子双定子风力发电机较常规风力发电机结构复杂、热源较多,发电机的发热与其结构尺寸、绕组等效和各材料导热系数直接有关.为保障电机稳定的运行和输出功率,因此需要分析和计算该发电机温升分布.基于电机的工作原理,设计了一台300kW的永磁/笼障混合转子双定子风力发电机.在此基础上,建立该发电机的热网络模型,推导出了气隙和笼障转子的热阻等效.分析和计算永磁/笼障混合转子双定子风力发电机各部件温升,并用有限元法进行结果验证.由结果分析可知,两种方法计算结果相对误差均小于10%,验证了分析方法的有效性和可行性.
Temperature Field Calculation of Hybrid Rotor Dual-Stator Wind Generator
Permanent magnet/cage barrier hybrid rotor dual-stator wind turbines have more complex structure and more heat sources than conventional wind turbines.The heat sources of the generator directly related to its structure size,equivalent winding and thermal conductivity of each material.In order to ensure the motor has stable operation and stable output power,the analyze and calculation of the generator temperature rise distribution is necessary.Base on the working principle of the motor,a 300k W permanent magnet/cage-barrier hybrid rotor dual-stator wind generator is designed in this paper.On this basis,establish the thermal network model of the generator,and deduct the equivalent thermal resistance of the air gap and cage-barrier rotor.Anal-ysis and calculation of temperature rise of components of permanent magnet/cage-barrier hybrid rotor dual-stator wind genera-tor,the results are verified by the finite element method.From the result analysis,the two methods relative error is less than 10%,which verifies the validity and feasibility of the analysis method used.
