摘要
介绍了用电磁公式和有限元两种方法计算具有３段圆弧极靴磁极的大型凸极同步电机稳态电抗，并以北京十三陵抽水蓄能电机为例进行了实算。首先，通过直轴和交轴磁场和磁路的计算确定同步电抗ｘｄ和ｘｑ；而后通过有限元计算，从负载运行状态下的磁场中获得同步电抗；最后对不同方法的结果进行了对比分析，并对直、交轴的耦合电抗也进行了分析计算。
Taking a large pumped storage machine at Shisanling Power Station as an exam ple,the calculation of the steady-state reactances of large salient synchronous machines with three arc pole shoe is discussed.The synchronous reactances x d and x q are determined directly from direct-axis and quadrature-axis armature magnetic fields at first,then the saturated synchronous reactances are calculated under rated load condition.Finally the coupling reactances between two axes are analysed.
