摘　　要：超瞬变电抗是分析凸极同步发电机发生三相对称短路故障的重要参数。它的主要分析方法是超导体闭合回路磁链守恒法和电路突然短路法。借助电磁有限元分析软件,分别采用磁链守恒法和短路法,计算了某台样机的超瞬变电抗,分析结果贴近实验数据,具有较高的精确度。Subtransient reactance is an important parameter to analysis of salient pole synchronous generator when three -phase symmetrical short-circuit happened.Its mainly analysis method is based on the superconductor closed-loop flux conservation principle and the method of suddenly short-circuit.In this paper,using the electromagnetic FEA software,the theory of flux conservation and the theory of short-circuit were adopted to calculate the subtransient reactance of a motor.The analysis result is very close to the experimental data,and has a very high accuracy.
