【摘要】 对表面插入式转子三相永磁同步发电机(PMSG)的负载特性进行了研究。用解析法推导出了实现零电压调节的条件。使用有限元分析计算磁场分布,根据磁场分布分析饱和对同步电抗的影响。实验结果表明:用饱和的双轴模型可对发电机的负载特性进行更精确的预测。更多还原

【Abstract】 In this paper,load characteristic of three-phase PM synchronous generator with surface insert rotor is studied.The condition to realize zero-voltage adjustment is derived by analytical method.Magnetic field distribution is computed by FEA and the influence of saturation on synchronous reactance is analyzed by it.The experiment result presents that the two-axle saturation model can accurately forecast load characteristic of generator.更多还原
