A mechanical vibration inverse analysis has been performed on 150MW hydro-power machine in order to identify unbalanced magnetic pull. FEM model of the machine is developed according to design data. The System Equivalent Reduction Expansion Process is involved in model validation during the power-machine experimental run. The unbalanced magnetic pull in the generator is calculated from the verified model and monitored data.
