A three-phase generator step-up transformer is rated 1000 MVA, 13.8 kV A/345 kV Y with Zeq = j0.10 per unit. The transformer high-voltage wind- ing has +10% taps. The system base quantities are Sbase 3 = 500 MVA VbaseXLL 13.8 kV VbaseHLL 345 kV Determine the per-unit equivalent circuit for the following tap settings: a. Rated tap b. -10% tap (providing a 10% voltage decrease for the high-voltage winding) Assume balanced positive-sequence operation. Neglect transformer winding resistance, exciting current, and phase shift.
