Estimation of synchronous machine parameter by standstill frequency response tests

This paper presents the identification of the linear parameters of a salient-pole synchronous machine at standstill by frequency response tests data (SSFR). The procedure consists in defining and conducting the frequency response tests, identifying the model structure, estimating the machine parameters. The parameters of operational impedances or in other terms, the reactances and the time constants are estimated. The obtained results are presented from tests on the synchronous machine of 1,5 kVA/380 V/1500 rpm.
