Stability Simulation - clearing islands

asked Nov 22 '16

I'm trying to figure out how I can clear only the island that the tripping element is causing during the tripping of the fault element right after distclearfault().

When I use psspy.tree(1,0) and psspy.tree(2,1), it clears ALL islands within the case which I do not want.

Activity TREE is a load flow function. It cannot be used in dynamics since there is no swing bus after generator conversion.

Normally you can run the simulation without clearing the "island" manually. PSS/E will automatically trip the island if there is no generator in it.
