Unformatted text preview: connected load through a transmission line having an impedance of Z line = 1 . 5 6 75 per phase. The load impedance is Z L = 20 6 30 per phase. The voltage at the load is 4.16 kV (line-to-line). Take phase a load voltage reference. 1. Draw the per phase equivalent circuit for phase a. 2. Compute I a , I b , I c , , and the voltages V an , V bn , V cn , V ab , V bc , V ca . 3. Compute the total complex power of load. 4. Compute the total complex power supplied by the generator. Problem 4. An industrial plant consists of several three-phase induction motors and draws 300 kW at 0.6 PF lagging from the substation bus. Find the kVAR rating of a capacitor bank to improve the PF to 0.9 lagging....
