Information

IEEE 4 nodes validation test case with the following characteristics

• balanced load,
  • power consumption on each phase P_1,2,3 = 1800 kW
  • power factor on each phase cosφ_1,2,3 = 0.9
• voltage step-up transformer (V_Pri=12.47 kV, V_Sec = 24.9kV),
• Y-D transformer

Revisions

• April 7, 2021, by Michael Wetter:
  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.
