摘 要:本文在基本绕组函数法理论的基础上,提出一种改进的绕组函数法,并以此来计算绕组结构复杂的磁阻型转子无刷双馈电机定子功率和控制两套绕组的各自自感及互感,并结合有限元分析结果验证了该改进的计算方法的有效性。然后,基于此改进的计算方法研究了定子两套绕组相对位置的变化对各自的自感及互感的影响。分析结果表明,定子两套绕组相对位置的变化对它们之间的互感有一定的影响。 关键词:无刷双馈发电机;磁阻型转子;绕组函数法;电感计算
Abstract: Based on traditional winding function method, the paper proposed an improved winding function method, which aimed to calculate the self-inductance and mutual inductance of power winding and control winding embedded in brushless doubly-fed generator with complex configuration. And combining the result of FEM verified the validity of this modified method .Then,based on the improved method , weather has an effect on the self-inductance and mutual inductance of them were researched,when the relative position of the two sets of stator windings changes.The results of the analysis show the change of the relative position of the two sets of stator windings influence the mutual inductance of them to some extent. Key words: brushless doubly-fed generator(BDFG); reluctance rotor; wind function method; inductance calculation
