Error with Dynamic Table and Three-phase Variable Load

Question

Hello everyone,

I'm trying to use a Dynamic Table component to feed a power profile (P and Q) from a CSV file into a Three-phase Variable Load. My goal is to make the load follow a time-varying active and reactive power pattern.

What I did:

• CSV file has three columns: time, P, Q (p.u.).

• I placed a Dynamic Table and imported the CSV directly (graphical method).

• I connected the scaled P to Pref and scaled Q to Qref of the load.

• I connected a constant 1 to the Enable input of the load.

• I also tried connecting Balance_en = 0 and ROC = 0 as suggested in some posts.

The problem:
When I try to compile the model, I get a huge list of errors

I want to know if it is another method to make an variable load using data from a csv. PLEASE HELP

Answer 1

Can you provide the huge list of errors? There's probably something in there that would point towards the exact issue

Answer 2

Hello Daniel,

Without the model itself, or at least the error log you are receiving, it would be very difficult for us to determine the reason for the compilation failure.

Based on my experience, I can say that the dimensions of input signals for this component can sometimes be counterintuitive. For example, I would advise you to double-check whether the signals connected to the 'Pref' and 'Qref' terminals have a dimension of 3 as indicated in the documentation (LINK).

Best,
