| Hi all!
I have problems with the line model in SimPowerSystems: everything
works fine when I use a 3-phase line. But when I change the number of
phases from N=3 to N=6 (i.e. a 2 circuit line) and enter the mutual
parameters, the simulation interrupts and the following error message
is displayed: "index exceeds matrix dimensions" - that's all.
Even the upfc_demo (which also utilizes a 6-phase line) doesn't work
and ends prematurely with this error message - unless I modify the line
to N=3.
So I decided to use 2 parallel 3-phase line models in my simulation -
although I lack the mutual interaction of the lines then. Works good.
But when I create a new subsystem out of those two parallel lines, the
Load Flow Estimator of the PowerGUI doesn't find a valid solution
anymore.
Does anybody know why is that?
Best regards,
J
