#6 (20 pts): A 20 MVA , 13.8 kV generator has the following data: Subtransient reactance 0.25 per unit. Negative Sequence reactance: 0.35 per unit Zero Sequence reactance: 0.1 per unit. Internal voltage E, = 1.0 per unit Calculate: 1. Subtransient current in the generator 2. Symmetrical components of the voltage Vao, Vai and Voz from point a to ground #7 (5 Pts): During a single Line-to-Ground fault (SLG) in a system a. Zero sequence current is the sum of the positive and negative sequence currents b. Positive, negative and zero sequence currents are equal c. Positive sequence current is the sum of negative and zero sequence currents d. Negative sequence current is the sum of positive and zero sequence currents
