IDENTFICATION OF ELECTRIC PARAMETERS OF SYNCHRONOUS GENERATOR USING INPUT_OUTPUT DATA SET

A novel technique to estimate the electric parameters of a synchronous generator from on-line measurement is presented in this paper. The proposed algorithm has two steps. In the first step, replacing the damper currents by higher derivatives of field and armature d-q currents, the electric parameters of the armature are estimated. In the second step, a current estimator is designed to estimate the damper winding currents, from which the parameters of field and damper windings are estimated. Simulation results show very good estimate of the electric parameters of a seventh order synchronous generator.
