I'm currently testing REGCAU+REECCU+REPCAU modeling in PSSE. I don't have any problem when initializing the case but when I checked the progress output bar, I found this msg.. can anybody helps me understand what this means? Sorry for

Model REPCAU1 Bus 1123 Q command 1.000 exceeds maximum 1.000

Sorry for the basic questions but hope someone can help with this. It'd be a really great help. Thanks :)

It says the Q command is at the ceiling value. This case doesn't actually affect your simulation but I wonder why is it that the Q output is 1.0 p.u?

This alert will be because of your Qgen during the Initialization (initial load flow condition) will be exceeding its limits of 1.0pu with the reference of Machine base as provided in the dyr file. Please use the realistic values of Qgen with reference to machine base MVA to fix this alert.
