A novel and fundamental approach towards field and damper circuit parameter determination of synchronous machine

In this era of advanced computing where complex algorithms and expensive approaches are used to determine the machine parameters of a synchronous machine, this paper proposes a novel, economical and yet fundamental approach towards estimation of the d- and q-axis field and damper circuit parameters of a low/medium power wound-field synchronous machine. The proposed novel methodology employs fundamental voltage, current, flux linkage relationships of the 3-phase wound-field synchronous machine in a-b-c reference frame theory. The methodology employed has been explained in length using analytical equations and experiments have been performed on a laboratory synchronous machine based on the developed method. Other equivalent circuit parameters have been determined using conventional tests. At the end, experimental findings have been presented and discussed.
