record parameter binding

[Volker Waurich]

Hi,

I would like to point to a bug regarding record parameter binbdings in power systems.

In PowerSystems.Examples.Spot.GenerationAC3ph.PowerAngle
within the component PowerSystems.AC3ph.Machines.Synchron3rd_ee generator that extends Partials.Synchron3rdBase the protected final parameter Coefficients.Synchron3rd c = Basic.Precalculation.machineSyn3rd(par,top.scale); exists.

The binding of this record is lost when printing +d=dumpdaelow.
Is there any possibility to forward the binding to the backend even if it is not yet evaluated?

Thank you.

That model no longer exists. The ​PowerSystems.Examples.AC3ph.Generation.PowerAngle model is reported to be under- and over-determined at the same time, maybe the root cause is still what is reported here.

Replying to casella:

That model no longer exists. The ​PowerSystems.Examples.AC3ph.Generation.PowerAngle model is reported to be under- and over-determined at the same time, maybe the root cause is still what is reported here.

That model now gives the same result as with the old frontend, which is that the backend claims that it's structurally singular. The machineSyn3rd call is also evaluated and all the generator.c fields are given bindings from the evaluated call (and if it couldn't be evaluated it would be moved to an equation, not just disappear).

So this now seems to be more of a backend issue rather than frontend, but regardless it might be a good idea to close this ticket and possibly open a new for the remaining issues.

Agreed!
