Ara and others,
I think the short circuit currents (3-phase SC) can be easily calculated by the
practical formula shown as below, isn’t it?
Id=V(0)/Zdd
where Id is the short circuit current (3-phase SC), V(0) is the initial voltage
at the failure point and Zdd is the self-reactance of the failure point.
So I think Matpower can also calculate it because all elements in the right
side of the formula can be achieved in the process of calculating the power
flow. But I am not familiar with the inner structure of Matpower.
I am wondering how to get the Zdd from it?

Wu,
as I wrote in my first email, I am not sure what each tool can, since I haven't
used any of them, but I thought maybe you would be interested in knowing about
the available Matlab Tools for PS-Analysis.
I am not sure what kind of analysis do you mean? Do you want to calculate only
the short circuit currents (3-phase SC)? Or the dynamic fault analysis? I guess
if it’s the 2nd one, then you should be able to use many tools. Short circuit
current calculation according to standard procedure (i.e. IEC 909 or ANSI
http://ieeexplore.ieee.org/iel1/28/5799/00222435.pdf?arnumber=222435) is
probably a bit trickier to program, because of its unsystematic nature. Maybe
that’s why most tools still don't have it.
Regards
Ara

Ara,
Thanks for your attention and suggestion.
I've read the paper and gotten more information about the PSAT from the
author's homepage. But unfortunately, the author said below words in one
presentation: The fault analysis and some other tools are still not available
as Matlab packages or toolboxes. So I have to go on looking for other tools.

Wu,
check this paper for some of the available Matlab based PS-Tools.
But it doesn't look like any of them has the IEC-standard short-circuit
calculation (if that is what you are looking for?).
I'm not sure thought, since I haven't used any of them.

Betreff: About the short circuit current
Hi all,
Can the Matpower calculate the short circuit currents?
If it can not, which one can? Please introduce one toolbox in MATLAB for me.
Thanks!
