No-load electromagnetic simulations of a hydropower generator considering the effect of rotor whirling

Abstract

Previous works [12], [13] carried out by two of the authors have had goals to examine the rotor movements and the stability of an industrial hydropower generator under a purely dynamic eccentricity motion. These two papers however only emphasised the importance of whirling as a mechanical issue and not as an electromechanical one. The present paper takes a step back and investigates what useful
