Buildings.Electrical.AC.ThreePhasesUnbalanced.Validation.IEEETests.Test4NodesFeeder.BaseClasses.IEEE4
Base model of the IEEE 4 nodes test feeder
Information
This is a partial model that is extended by all the other validation test cases. This model defined replaceable probes and transformer so they can be easily changed when implementing the different tests.
More information can be found in each model that extends this one.
Reference results
The reference results for the tests are saved as parameter of the model and compared to the simulated ones. The error between the results (herein called Xmodel) and the references (herein called Xref) are computed in both absolute and relative way. Note that Xmodel and Xref can be either voltage amplitudes or phase angles.
Errabs = Xmodel - Xref
Err% = Errabs / Xref
The variables that store the results of the comparison are listed in the table below
