The turbogenerator models of 1d-1q and 1d-2q with or without xfldl are described briefly.To calculate the parameters in the model for the turbogenerator, 2D-FE method is used. The steadystate and the transient state parameters have been calculated, and the results are well verified by experiments. An eletromechanically coupled shafts torsional vibration simulation program for large turbogenerator set is developed, and it is verified by the experimental results obtained from a torsional vibration test stand designed by authors. The influence of the turbogenerator model selected on the calculation of shafts torsional vibration is analyzed in details. Proper turbogenerator model is recommended for the calculation of the torsional vibration.
