Abstract:
During hydro generator's repair done with whole disassembling of the rotor and the stator, followed by assembling the machine, possible axia displacement of the rotor and stator or uneven pole shift may occur. In these cases when the hydro generator is excited in idle running, unbalanced electromagnetic forces occur. They cause vibrations in the bearing assemblies with amplitude proportional to the excitation current. The task of the current elaboration is to create a simulation model based on FEM, applicable for quality and quantity estimation of the possible causes, causing vibrations in hydro generator during exciting in idle running.
