| Abstract: | This paper presents a 2D sinusoidal eddy current field analysis of a 125 MW turbogenerator under asynchronous operation by means of FEM. The cases of both stator and rotor are smooth or slotted, field winding is open or closed, rotor with or without wedges are studied. Through calculation and analysis, some useful conclusions for numerical calculation, analysis and practical operation are obtained. |
