Fields§
§base: TurbineGovernorDynamics§a: Option<f64>Turbine power time constant numerator scale factor (a). Typical value = 0,8.
b: Option<f64>Turbine power time constant denominator scale factor (b) (>0). Typical value = 1.
db1: Option<f64>Intentional dead-band width (db1). Unit = Hz. Typical value = 0.
db2: Option<f64>Unintentional dead-band (db2). Unit = MW. Typical value = 0.
eps: Option<f64>Intentional db hysteresis (eps). Unit = Hz. Typical value = 0.
fidle: Option<f64>Fuel flow at zero power output (Fidle). Typical value = 0,18.
gv1: Option<f64>Nonlinear gain point 1, PU gv (Gv1). Typical value = 0.
gv2: Option<f64>Nonlinear gain point 2,PU gv (Gv2). Typical value = 0.
gv3: Option<f64>Nonlinear gain point 3, PU gv (Gv3). Typical value = 0.
gv4: Option<f64>Nonlinear gain point 4, PU gv (Gv4). Typical value = 0.
gv5: Option<f64>Nonlinear gain point 5, PU gv (Gv5). Typical value = 0.
gv6: Option<f64>Nonlinear gain point 6, PU gv (Gv6). Typical value = 0.
ka: Option<f64>Governor gain (Ka). Typical value = 0.
kt: Option<f64>Temperature limiter gain (Kt). Typical value = 3.
lmax: Option<f64>Ambient temperature load limit (Lmax). Lmax is the turbine power output corresponding to the limiting exhaust gas temperature. Typical value = 1.
loadinc: Option<f64>Valve position change allowed at fast rate (Loadinc). Typical value = 0,05.
ltrate: Option<f64>Maximum long term fuel valve opening rate (Ltrate). Typical value = 0,02.
mwbase: Option<f64>Base for power values (MWbase) (> 0). Unit = MW.
pgv1: Option<f64>Nonlinear gain point 1, PU power (Pgv1). Typical value = 0.
pgv2: Option<f64>Nonlinear gain point 2, PU power (Pgv2). Typical value = 0.
pgv3: Option<f64>Nonlinear gain point 3, PU power (Pgv3). Typical value = 0.
pgv4: Option<f64>Nonlinear gain point 4, PU power (Pgv4). Typical value = 0.
pgv5: Option<f64>Nonlinear gain point 5, PU power (Pgv5). Typical value = 0.
pgv6: Option<f64>Nonlinear gain point 6, PU power (Pgv6). Typical value = 0.
r: Option<f64>Permanent droop (R) (>0). Typical value = 0,04.
rmax: Option<f64>Maximum fuel valve opening rate (Rmax). Unit = PU / s. Typical value = 1.
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 the free power turbine of an aero-derivative unit, for example. Typical value = 0,5.
t3: Option<f64>Turbine exhaust temperature time constant (T3) (>= 0). T3 represents delay in the exhaust temperature and load limiting system. Typical value = 3.
t4: Option<f64>Governor lead time constant (T4) (>= 0). Typical value = 0.
t5: Option<f64>Governor lag time constant (T5) (>= 0). If = 0, entire gain and lead-lag block is bypassed. Typical value = 0.
tltr: Option<f64>Valve position averaging time constant (Tltr) (>= 0). Typical value = 10.
vmax: Option<f64>Maximum turbine power, PU of MWbase (Vmax) (> GovGAST1.vmin). Typical value = 1.
vmin: Option<f64>Minimum turbine power, PU of MWbase (Vmin) (< GovGAST1.vmax). Typical value = 0.
