摘要：

The accurate prediction of synchronous machine steady-state and transient performances requires the accurate determination of the machine parameters. This paper presents a model for the d- and q-axis synchronous reactances in which the effects of both the d- and q-axis saturation factors and the cross-magnetizing phenomenon are included. The variations of the d- and q-axis mutual reactances versus the d- and q-axis ampere-turns are also shown. The results obtained by using this model are found to be in a good agreement with those measured experimentally. These results show also that the saturation effects on the d- and q-axis mutual reactances could be large and its effect on the q-axis reactance could be larger than that on the d- axis reactance. Furthermore, the results demonstrate that the effect of the cross-magnetizing phenomenon could be appreciable and its negligence or improper representation could lead to inaccurate values for the machine reactances.
