Direct determination of the steady state in schronous machines for periodic variability of mechanical torque
Languages of publication
This paper presents an algorithm that uses the harmonic balance method for finding the steady-state solution in the moment of excited synchronous machine with periodic mechanical component of the alternating depending on the angle of rotation of the rotor. The problem is complicated because the presence of periodic component leads to problems of nonlinear. This procedure allows the direct determination of the Fourier spectra of the most important volumes describing the synchronous machine. Sample calculations were performed for a synchronous motor operating in the state of synchronism and fixed mechanical load torque varying periodicaly at a specifed course.
