Hydro Turbines

 

Description

This component models an IEEE type hydro turbine.  

 

The inputs to this model are per-unit speed w, per-unit speed reference Wref and gate position z.  The outputs are the mechanical torque Tm (which is input to the Synchronous Machine and initial gate position zi (which is input to the associated Hydro Governor for initialization.
