Does anyone has any idea how to resolve the initial condition suspect for GAST2A gas turbine governor model? Issue is with the state (K+5) temperature control. The temperature initialised at maximum Tc. Thanks
When the message during initialization for a GAST2A models says:
Model GAST2A Bus 1000 [abc 18.000] Machine "1" :
TEMPERATURE CONTROL INITIALIZED CORRECTLY AT MAXIMUM
STATE( 14720) MAY SHOW AS SUSPECT INITIAL CONDITION
its state (K+5) appears in the INITIAL CONDITIONS SUSPECT table as:
14720 0.44871 -0.49574 GAST2A K+5 1000 abc 18.000 1
This is not considered a model error, so no need to resolve it.
+1. It is only due to the implementation of the temperature control. If you look carefully, if the exhaust temperature is lower than the limit Tc, then the integrator continuously integrates and hits the wind up limit. So there should actually be a Dstate <> 0 if no temperature limit is hit
I use a WSIEG1 model to this generator but we change the model for GAST2A, When we use de WSIEG1 in this case, we don't have a suspect conditions and the simulation don't present other machine trip. Our final objetive is model this plant with a URCSCT model because this is a single shaft combined cy
It is difficult to answer this question without seeing your input data, and replicating your issue from there. If you can send your RAW and DYR files then perhaps I or some of the other forum readers can assist you.
