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 (linetoline). 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 threephase 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....
