I've been working on different dynamics analysis of network using PSCAD, but still puzzled on how I can use the values or plot from the software to generate an Eigenvalues or diagram during a small-signal analysis.
I have asked this question on 2014 to PSCAD support, and they said that:
" At this time, there is no way in PSCAD to define a transfer function using State Space and thus we are also not able to plot the Root Locus.
However, the new PSCAD 4.6 (too be released in a few months) will have a new component that will allow you to define a transfer function using state space. You will be allowed to enter the matrices A, B, C, D that define the behavior.
We are also looking into the Root Locus representation to see if it is possible to render that too. For now, it is on our feature request list. "
