GovGAST

Class Description

Single shaft gas turbine.

Attributes

Name Type Description
at PU Ambient temperature load limit (Load Limit). Typical value = 1.
dturb PU Turbine damping factor (Dturb). Typical value = 0,18.
kt PU Temperature limiter gain (Kt). Typical value = 3.
mwbase ActivePower Base for power values (MWbase) (> 0). Unit = MW.
r PU Permanent droop (R) (>0). Typical value = 0,04.
t1 Seconds 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 Seconds 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 Seconds Turbine exhaust temperature time constant (T3) (>= 0). Typical value = 3.
vmax PU Maximum turbine power, PU of MWbase (Vmax) (> GovGAST.vmin). Typical value = 1.
vmin PU Minimum turbine power, PU of MWbase (Vmin) (< GovGAST.vmax). Typical value = 0.
