Abstract :
A new approach to calculate and analyze the electromagnetic forces on the end windings of large turbine generators is presented. This approach, the so-called quasi-three dimensional (quasi-3D) finite-element method (FEM), takes advantages over the conventional 3D FEM in memory size and time efficiency. The distributions of the electromagnetic field and forces on end windings of a 100 MW generator are analyzed. Incorporating advanced computer graphics, the analysis can be carried out under a visual and interactive environment. The theoretical results are experimentally verified
