Determination of salient pole synchronous machines electromagnetic parameters from the SSFR test

Presented article deals with the determination of hydrogenerator electromagnetic parameters from the SSFR test. A method utilized to prepare the results is finite element method based on the module of Steady State AC Magnetic 2D application. Obtained reactances could be determined after an application of own made program used to fit the curves (magnitude and phase characteristic of operator transmittances) to the data coming from the simulation in order to designate the time constants. An impact of saturation effect in stator and rotor steels was researched on obtained reactances in different working states of synchronous machine.
