Revision history [back]

Earlier I was facing the issue of LF while integration wind generation in the system, now it is being solved using flat start. But while going for dynamic analysis, its shows initial conditions suspect for many of the conventional generator parameters along with WT3 model of wind. When moving forward to initializing and applying bus fault showing some values in the output bar after clearing fault running it for more of 10 secs, after 1 sec of clearing fault showing zeros under all heads. Kindly guide through this. I am not able to understand the reason behind same. While running the dynamic simulation without wind integration everything is running fine.
