It basically takes the system base power, which is a three-phase value, and calculates the per-phase base power. This is necessary for obtaining the correct per-unit values of current and voltages in a three-phase power system connected to a positive-sequence-equivalent system.
For instance, if the system base is 100 MVA, in a positive-sequence-equivalent grid, the phase base is 33.33 MVA.
