| Abstract: | The current curves of the windings in turbogenerators at sudden 3-phase short circuit are calculated by using the transient electric-magnetic field FEM. After the results are decomposed and mediated, the transient parameters of turbogenerators are made out. The structure of the teeth and slots and the saturation in turbogenerators are considered effectively. The CPU time for solving non - linear equations of higher degree in a computer is reduced by using "Newton and Rphson" reiterative method and ICCG algorithm. So the method in this paper is very practical. |
