IEEE 4 node test feeder model with balanced load and Y - D connection (step up)

Extends from BuildingSystems.Electrical.AC.ThreePhasesUnbalanced.Validation.IEEETests.Test4NodesFeeder.BaseClasses.IEEE4.

Information

IEEE 4 nodes validation test case with the following characteristics

  • balanced load,
    • power consumption on each phase P1,2,3 = 1800 kW
    • power factor on each phase cosφ1,2,3 = 0.9
  • voltage step-up transformer (VPri=12.47 kV, VSec = 24.9kV),
  • Y-D transformer

    Set better start values loadRL(load1(v(start = {13000, 20000}))) because for one component, the start value is far from a solution and if specified, Dymola 2022 beta3 fails to initialize the model.
    This is for #2432.
  • November 28, 2016, by Michael Wetter:
    Set start value for loadRL(load1(v(each start = 15000))) which is needed for Dymola 2017 to find the correct solution.
    This is for #584.
