A coupled finite-element state-space approach for synchronous generators. II. Applications

Used here is the coupled finite-element state-space (CFE-SS) approach, based on the natural ABC flux-linkage frame of reference, to predict a salient-pole synchronous generator's parameters and performance, including damper bar currents and iron core losses, under open-circuit short-circuit impedance, and infinite bus load conditions. The full synergistic effects of space harmonics resulting from the magnetic circuit geometry, saliency, saturation, winding layouts, slotting, and time harmonics resulting from the nonsinusoidal armature currents and field as well as damper bar currents, are included in the simulations.
