摘　　要：为计算12/3相双绕组异步发电机多达上百的相间槽漏感,在槽比漏磁导求取和绕组与线圈边连接关系确定方面采用了新的分析方法。通过对定子圆底槽各层的分片处理,由数值方法推导了层间槽比漏磁导计算公式,并给出了相应的计算结果。仿照图论结合回路电流法分析电路网络的过程,列写了表示线圈边支路电流与一相绕组回路电流间的关联矩阵,用规范统一的编程方法计算各相绕组间的槽漏感,并对其中几个电感值进行了定性分析。所用分析方法通用性强,对绕组连接复杂多相异步电机定子槽漏感参数计算优势明显。In order to calculate hundreds of phase slot leakage inductances of a 12/3-phase dual stator-winding induction generator, new analysis methods are utilized to acquire slot leakage permeances and determine relationships between windings and coil sides. With slicing each layer of the round-bottom stator slot into thin segments, the formulas for calculating slot leakage permeances between slot layers are derived and corresponding calculated results obtained. By combining graph theory with loop current method for circuit network analysis, the incidence matrix between coil-side branch currents and one-phase winding loop currents are established, from which the normalized and unified programming approach is performed to phase slot leakage inductance calculation. Some calculated inductances are given and qualitative analysis is carried out. The proposed analysis methods are of versatility, which is especially suited to calculate stator slot leakage inductance parameters of the multi-phase induction machine with complicated winding connection.
