Single shaft gas turbine.
Fields§
§base: TurbineGovernorDynamics§at: Option<f64>Ambient temperature load limit (Load Limit). Typical value = 1.
dturb: Option<f64>Turbine damping factor (Dturb). Typical value = 0,18.
kt: Option<f64>Temperature limiter gain (Kt). Typical value = 3.
mwbase: Option<f64>Base for power values (MWbase) (> 0). Unit = MW.
r: Option<f64>Permanent droop (R) (>0). Typical value = 0,04.
t1: Option<f64>Governor mechanism time constant (T1) (>= 0). 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.
t2: Option<f64>Turbine power time constant (T2) (>= 0). 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 free power turbine of an aero-derivative unit, for example. Typical value = 0,5.
t3: Option<f64>Turbine exhaust temperature time constant (T3) (>= 0). Typical value = 3.
vmax: Option<f64>Maximum turbine power, PU of MWbase (Vmax) (> GovGAST.vmin). Typical value = 1.
vmin: Option<f64>Minimum turbine power, PU of MWbase (Vmin) (< GovGAST.vmax). Typical value = 0.
