GovGAST
Class Description
Single shaft gas turbine.
Attributes
Name | Type | Description |
---|---|---|
at | PU | Ambient temperature load limit (<i>Load Limit</i>). Typical value = 1. |
dturb | PU | Turbine damping factor (<i>Dturb</i>). Typical value = 0,18. |
kt | PU | Temperature limiter gain (<i>Kt</i>). Typical value = 3. |
mwbase | ActivePower | Base for power values (<i>MWbase</i>) (> 0). Unit = MW. |
r | PU | Permanent droop (<i>R</i>) (>0). Typical value = 0,04. |
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. |
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. |
t3 | Seconds | Turbine exhaust temperature time constant (<i>T3</i>) (>= 0). Typical value = 3. |
vmax | PU | Maximum turbine power, PU of MWbase (<i>Vmax</i>) (> GovGAST.vmin). Typical value = 1. |
vmin | PU | Minimum turbine power, PU of MWbase (<i>Vmin</i>) (< GovGAST.vmax). Typical value = 0. |
