This test system aims to show how a very small three-phase system should be assembled for simulation. Its results should be compared to the example IEEE4_MonoTri, in order to show what to expect from the hybrid transformer. Here, all buses are modeled as three-phase buses.
This example is not a dynamic system, and therefore the voltages and angles from all buses are static during the simulation. The simulation just calculates the initialization variables, which are the solution for the three-phase power flow. The results can be verified against any tool that calculates a three-phase power-flow.
