Estimation of synchronous machine parameters by standstill tests
چکیده انگلیسی

In this paper we present the results of a time-domain identification procedure to estimate the linear parameters of a salient-pole synchronous machine at standstill.A new approach is proposed for the estimation of synchronous machine coupled to DC-chopper and Pseudo Random Binary Sequences excitations; using data recorded during steady-state operation of the chopper-machine unit. This procedure consists of defining and conducting the standstill tests, identifying the model structure, estimating the corresponding parameters, and validating the resulting model. The signals used for identification are the different excitation voltages at standstill and the flowing current in different windings. We estimate the parameters of operational impedances, or in other terms, the reactances and the time constants.The results are presented from tests on a synchronous machine of 3 kVA/220 V/1500 rpm.
