Single mass turbo-generator rotor
Information
This model can be regarded as a default model.
Turbine-rotor and generator-rotor together represent one single stiff rotating mass, characterised by its mechanical time constant H. The model therefore has one single mechanical degree of freedom. This component does not need an additional torque model.
No pole pair reduction of equations of motion is performed.
Therefore phi and w represent the mechanical angle and angular velocity.
