GovGAST Class

Single shaft gas turbine.

ID	Тип	Описание	Количество
mwbase	ActivePower	Base for power values (<i>MWbase</i>) (> 0). Unit = MW.	1..1
r	PU	Permanent droop (<i>R</i>) (>0). Typical value = 0,04.	1..1
t1	Seconds	Governor mechanism time constant (<i>T1</i>) (>= 0). <i>T1</i> 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.	1..1
t2	Seconds	Turbine power time constant (<i>T2</i>) (>= 0). <i>T2</i> represents delay due to internal energy storage of the gas turbine engine. <i>T2</i> 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.	1..1
t3	Seconds	Turbine exhaust temperature time constant (<i>T3</i>) (>= 0). Typical value = 3.	1..1
at	PU	Ambient temperature load limit (<i>Load Limit</i>). Typical value = 1.	1..1
kt	PU	Temperature limiter gain (<i>Kt</i>). Typical value = 3.	1..1
vmax	PU	Maximum turbine power, PU of MWbase (<i>Vmax</i>) (> GovGAST.vmin). Typical value = 1.	1..1
vmin	PU	Minimum turbine power, PU of MWbase (<i>Vmin</i>) (< GovGAST.vmax). Typical value = 0.	1..1
dturb	PU	Turbine damping factor (<i>Dturb</i>). Typical value = 0,18.	1..1
