This model describes a simplified steam turbine unit, with a high pressure and a low pressure turbine.

The inlet flowrate is proportional to the inlet pressure, and to
the `partialArc` signal if the corresponding connector is
wired. In this case, it is assumed that the flow rate is reduced by
partial arc admission, not by throttling (i.e., no loss of
thermodynamic efficiency occurs). To simulate throttling, insert a
valve before the turbine unit inlet.

The model assumes that a fraction `hpFraction` of the
available hydraulic power is converted by the HP turbine with a
time constant of `T_HP`, while the remaining part is
converted by the LP turbine with a time constant of
`L_HP`.

This model does not include any shaft inertia by itself; if that
is needed, connect a `Modelica.Mechanics.Rotational.Inertia`
model to one of the shaft connectors.

The model requires the `Modelica.Media` library
(`ThermoFluid` does not compute the isentropic enthalpy
correctly).
