Analiza pracy maszyny synchronicznej przy zaburzeniach momentu mechanicznego zależnych od kąta obrotu

This paper presents an algorithm for direct determination of steady-state solutions of synchronous machine equations when some perturbations occur in a mechanical load and bound up with angle of rotation. Algorithm allows to determine directly, precisely and clearly the Fourier spectra of machine currents and angular velocity. Exemplary computations are done for a synchronous motor running synchronously and loaded by a mechanical torque with a periodic ac component.
