Modelica Standard Library 4.0.0

Illegal call to zeros with negative argument

2

The call to `zeros(n_q - 1)` here: https://github.com/modelica-3rdparty/PowerSystems/blob/69fd1e7381fb50e6a0bc77d9ba168e9d6a7d9a6a/PowerSystems/Examples/AC3ph/Precalculation.mo#L1142 seems to come down to `zeros(-1)`, if we resolve `n_q`: https://github.com/modelica-3rdparty/PowerSystems/blob/69fd1e7381fb50e6a0bc77d9ba168e9d6a7d9a6a/PowerSystems/Examples/AC3ph/Precalculation.mo#L1137 https://github.com/modelica-3rdparty/PowerSystems/blob/69fd1e7381fb50e6a0bc77d9ba168e9d6a7d9a6a/PowerSystems/Examples/AC3ph/Precalculation.mo#L1116 giving the expression `zeros(size(fill(0, 0), 1) - 1)` ==> `zeros(-1)`,...

Could not evaluate structural parameter (or constant): n_r which gives dimensions of array: L_r[n_r]. Array dimensions must be known at compile time.

In many simulation appears the message: "Could not evaluate structural parameter (or constant): n_r which gives dimensions of array: L_r[n_r]. Array dimensions must be known at compile time." Thank you

This is a companion ticket of #31. that one referred to data present in Examples.Data.Lines, this one refers to the two lines in AC3ph.Lines.Parameter.RXline. Here there is an evident mistake...

To help understand how AC1ph_DC models work, I've prepared "CompareMSL.mo", that I enclose. It contains twin Power System and MSL models of a simple Ac1ph_DC system. I've added some "info"...

Consider AC1ph_DC.Impedances.Inductor. The inductor reactance is entered as a 2x2 matrix, containing [xs[1],xm; xm,xs[2]] This matrix is directly accessible through the parameter dialog box. This implies that the user can...

Consider Examples.Data.Lines. It contains twin line data for RXline components and PIline components. The latter have the same info of the former, plus additional info regarding transverse susceptances and conductances....
