Thermal (Steam) Turbines

The inputs to this model are per-unit speed w, per-unit speed reference Wref, per-unit control valve position Cv and per-unit intercept valve position Iv from the corresponding Thermal (Steam) Governor. The outputs are the mechanical torques Tm1 and Tm2 and are output from the HP and LP turbines respectively.
