| Abstract: | three-dimensional finite element method is applied to calculate electromagnetic field,eddy losses and thermal field of large turbogenerator in the end zone. The relative mathematic models andboundary conditions are studied and given.The special calculative methods are deduced. As an exam-ple, the QFS-300-2 turbogenerator is Galculated. Its power chart under various limitry conditions is obtained. All calculated results in this paper are in good agreement with the measured results.The stud-ied conclusions can be used to guide the secure operation of large turbogenerator. |
