Zusammenfassung:As part of EPRI Program RP 1288-1, Improvement in Accuracy of Prediction of Electrical Machine Constants, a method has been developed for calculating small-signal operational inductances. The method utilizes solutions to the magnetic diffusion equation, solved by the finite-element method. To faithfully simulate the behavior of the rotor iron for small-signal perturbations, measured values for incremental permeability are used.
