Kurzfassung englisch:
The eddy currents in the clamping plates of large hydro-generators
generate additional losses and can cause local heating problems. Thus, an accurate determination of these losses is a matter of particular interest in the machine design. The paper presents an analytic method for the determination of these losses. Thereby, the 3D time harmonic diffusion equation will be solved. Additionally, the 3D nonlinear finite element analysis of the end region of a 500 MVA hydro-generator for the calculation of these losses is shown. The results of both methods are compared with the values obtained from measurements on the 500 MVA hydro-generator.
