Initial Conditions Suspects

Hi everyone,

I'm performing a dynamic simulation for a large power system, and I got initial condition suspects for CMLDBLU2 models. Could someone help me understand how to resolve it, thanks.

Have you checked the log file for warnings on the CMLD models? These types of messages may exist: At bus 4, CMLD load bus voltage of 0.9471 pu is below 0.95 minimum. Original feeder Z of 0.2295 +j 0.2295 pu on SBASE will be reduced in an attempt to bring V up above 0.95 pu

Hello, yeah I figured out it and could solve it. But I'm trying to solve the CMLDBLU2 models. Any comments to start with would be appreciated.

Didn't CMLDBLU2 messages disappear when you fixed the governor problems????

perolofl (Apr 20 '3)

No, I have mentioned a part of the initial conditions suspects in this post. There are about 70 of CMLDBLU2 suspects in the original log file. I'm doing this dynamic simulation for a large power system.

Just to be sure what you mean. Have you redone the inialisation after correcting generators at bus 2 and 3?

perolofl (Apr 20 '3)

Yeah, I did. I initialized the case after correcting the generators.
