Calculation of END region magnetic field and circulating losses for turbo-generators using a coupled field and circuit equations method

A coupled field and circuit equations method is presented to calculate the end region magnetic field, the current distribution in stator winding strands and the circulating losses of the stator winding in large turbogenerators. In the calculation, the non-uniform distribution of current density in t...

Zusammenfassung:	A coupled field and circuit equations method is presented to calculate the end region magnetic field, the current distribution in stator winding strands and the circulating losses of the stator winding in large turbogenerators. In the calculation, the non-uniform distribution of current density in the stator winding and the influence on the end region magnetic field of copper shield are considered. Finally, the effect of the transposed angle on the circulating losses is analyzed.
