Jul 30, 1999 · We will now calculate the per-unit quantities for a line-to-line voltage of a 162 kV and a total three-phase power of 24,000 kW. Line-to-Line Base. Per - unit Voltage = Per - unit Power = Line-to-Neutral Base. For an actual line-to-line voltage of 162 kV, in a balanced three-phase system, the line to neutral voltage is , and. Per-unit voltage =

Let’s return to Fig. 3, repeated here for convenience: Fig. 3. Another fundamental relation for power flow F12 (learned by EE students in EE 303) is: (16) We will derive this equation later in the course. Here, θ1 and θ2 are the angles of the voltage phasors at buses 1 and 2 respectively. Recall that we applied some approximations to eq. (1).
