Initial conditions suspects in CMLDBLU2

Hello everyone, I'm having trouble in figuring out the cause for the following initial conditions suspect.

 INITIAL CONDITIONS SUSPECT:
 I   DSTATE(I)    STATE(I)     MODEL             STATE     BUS#-SCT X-- NAME --X BASKV  ID
  83630   0.69850E-04 -0.68402E-02 CMLDBLU2           K+1     10000     Load 1   12.500  1
  83632   0.59582E-04  0.17921E-02 CMLDBLU2           K+3     10000     Load 1   12.500  1

I want to figure out if this happens due to a model error or due to a voltage issue. Thank You

In theory, the DSTATE value should be zero, but in practice, a very small value is workable. I supplement the "initial conditions suspect" table listing with the plotting/evaluation of channels (Pe,Qe,..) after a dynamic simulation under no disturbance for the period of interest (a flatstart for 10 sec.?) An acceptable response would be a flat line with max. deviations smaller than 10e-2. Use PSSPLT to evaluate max. deviations. If the plot has larger deviations or oscillations, model parameters need adjustments.
