Single shaft gas turbine.<br/>
Attribute
Public PU
  at
Details:
Notes: Ambient temperature load limit (Load Limit).  Typical Value = 1.<br/>
Public PU
  dturb
Details:
Notes: Turbine damping factor (Dturb).  Typical Value = 0.18.<br/>
Public PU
  kt
Details:
Notes: Temperature limiter gain (Kt).  Typical Value = 3.<br/>
Public ActivePower
  mwbase
Details:
Notes: Base for power values (MWbase) (#gt; 0).<br/>
Public PU
  r
Details:
Notes: Permanent droop (R).  Typical Value = 0.04.<br/>
Public Seconds
  t1
Details:
Notes: Governor mechanism time constant (T1).  T1 represents the natural valve positioning time constant of the governor for small disturbances, as seen when rate limiting is not in effect.  Typical Value = 0.5.<br/>
Public Seconds
  t2
Details:
Notes: Turbine power time constant (T2).  T2 represents delay due to internal energy storage of the gas turbine engine. T2 can be used to give a rough approximation to the delay associated with acceleration of the compressor spool of a multi-shaft engine, or with the compressibility of gas in the plenum of a the free power turbine of an aero-derivative unit, for example.  Typical Value = 0.5.<br/>
Public Seconds
  t3
Details:
Notes: Turbine exhaust temperature time constant (T3).  Typical Value = 3.<br/>
Public PU
  vmax
Details:
Notes: Maximum turbine power, PU of MWbase (Vmax).  Typical Value = 1.<br/>
Public PU
  vmin
Details:
Notes: Minimum turbine power, PU of MWbase (Vmin).  Typical Value = 0.<br/>
