Information

This model tests the Electrical.Buses.EquivalentGrid model. The internal voltage source is initialized to provide the required initial modulus and phase of the port voltage.

The equivalent grid model computes an internal impedance of 6.323+j*63.23 Ohm, corresponding to a short circuit power of 2272 MVA, which gives the rated 2500 MVA when multiplied by the c-coefficient, as computed by shortCircuitCapacity.y. This verification is carried out by the equivalent circuit in the lower part of the diagram.
