Hi Guys,

I have created a user model of the exciter and would like to analyse / access the internal / calculation variable and plot it in the dynamic simulation in PSSE.

I just wonder how to do it since i can not find any information about it.

This is how my code looks like. I would like to plot the VERROR.

The UDM runs fine for your information

  SUBROUTINE MYMODELEXC(MC,ISLOT)

  INCLUDE 'COMON4.INS'   
  INTEGER ISLOT,IB,MC,J,K,IM,IBUS

  INTRINSIC ABS,MAX
  REAL VERROR

  IF (MODE .EQ. 8) THEN
   CON_DSCRPT(1) = 'K'
   CON_DSCRPT(2) = 'Te'
  ENDIF

  J = STRTIN(1,ISLOT)
  K = STRTIN(2,ISLOT)

  IB = ABS(NUMTRM(MC))
  IF(IB.LE.0)RETURN

  IF (MODE .EQ. 1) THEN
  ! MODE 1  Initialization 
  STATE(K) = EFD(MC)
  VREF(MC) = ABS(VOLT(MC))+EFD(MC)/CON(J)
  ENDIF
  IF (MODE .EQ. 2) THEN
 ! MODE 2 CCalculation of derivatives 
  VERROR = VREF(MC)-ECOMP(MC)                       ! This varibale i want to plot in PSSE
  DSTATE(K) = (CON(J)*VERROR-STATE(K))/CON(J+1)
  ENDIF
  IF (MODE .EQ. 3) THEN
  !MODE 3 SET EFD
  EFD(MC) = MAX(STATE(K),0.0)
  !EFD(MC) = VREF(MC)
  ENDIF

  IF (MODE .EQ. 4)THEN
  ! MODE 4, set number of integrators / select the highest
  NINTEG = MAX(NINTEG,K)
  ENDIF

  RETURN  
  END
