摘　　要：为计算12/3相双绕组异步发电机多达上百的相间谐波漏感,在两线圈间谐波电感的求取和绕组与线圈连接关系确定方面采用了新的分析方法。以单一线圈而不以一相绕组为基础,通过总电感减去基波电感的方法计算两线圈间的谐波电感,并在区分控制绕组和功率绕组情况下给出了异步发电机任意2个定子槽中线圈间谐波电感值。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谐波漏感,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谐波漏感参数计算优势明显。In order to calculate hundreds of phase harmonic leakage inductances of a 12/3-phase dual stator-winding induction generator, new analysis methods are utilized to acquire harmonic inductances between two coils and determine relationships between windings and coils. Based on a coil instead of a phase winding, the harmonic inductance between two coils is calculated by subtracting the fundamental inductance from the total inductance, thus obtaining the control winding harmonic inductances and the power winding harmonic inductances, respectively, for any two stator slot coils of the induction generator. By combining graph theory with loop current method for circuit network analysis, the incidence matrix between coil branch currents and one-phase winding loop currents are established, from which the normalized and unified programming approach is performed to phase harmonic leakage inductance calculation. Some calculated inductances are given and qualitative analysis is carded out. The proposed analysis methods are of versatility, which is especially suited to calculate stator harmonic leakage inductance parameters of the multi-phase induction machine with complicated winding connection.
