Example model of a large steam turbo-group with generator rotor.
(Aux, HP1, HP2, MP, LP, Generator, Exciter).
The rigid massive rotating parts are connected with massless elastic shafts. The model therefore has several mechanical degrees of freedom and allows the study of coupled electrical and mechanical resonances.
An appropriate torque model has to be connected to SteamTurboGroup.blades.
No pole pair reduction of equations of motion is performed.
Therefore phi and w represent the mechanical angle and angular velocity.
