English abstract:
The reliability of the loss calculation is a very important issue during
the electrical design phase of large synchronous generators. The paper
presents a fully 3D finite element approach for the computation of eddy
current losses in the stator clamping parts of a 450 MVA hydro generator.
To take into account for saliency and saturation effects, the analyses
utilize the fundamental harmonic wave as well as the third harmonic wave
of the excitating end region field. The results obtained from time-harmonic
and transient analyses are compared regarding the total eddy current losses
as well as their local distributions.
