In PLNTBU1 there are two output signal, Wext and Pext which are the inputs in the two REAX4BU1 which are modelled.
When I have REPCA PPC, I modified Vref or Pref in order to get a change in the voltage or active power repectively. In the PLNTBU1, to get a voltage step at control bus, should Vref be modified? And to have a change in Pref should Plantpref be modified? When I changed Vref I can see an voltage step at POI whereas a change in Plantpref does not change anything.
What are AUX VAR used for? Are they linked to the Auxiliary-signal models (CHAAUT, CPAAUT, etc...) I don't have?
In REAX4BU1 there are wref1 and pref1? How are these vars calculated? Is something I can change?
i am performing MNOD26 and 27, and usually I modified kp, kpg, ki and kig. In this case, in PLNTBU1 I suppose the same k should be modified. But in REAX4BU1, can kw1 and kp1 be modified?
