a Problem Description Figure 1 shows a three-phase generator feeding a load through a feeder. Given: va(t) = 312 cos 377t, vy(t) = 312 cos(377t + 120°), ve(t) = 312 cos(377t + 240°) Ri = 412, L1 = 10 mH, R = 152, L = 0.25 H A capacitor bank connected in Delta is added to improve the power factor of the load. V 1. Design the value of the capacitance C, required to obtain a power factor of 0.92 lagging, 2. Simulate the circuit using appropriate software and verify the results. 3. Show the voltage and current waveforms in all three phases of RL load. 4. Show the current and voltage waveforms in Capacitor bank. The circuit is a linear circuit and at steady state, so phasors can be used to analyze this circuit. Being balanced, a per-phase equivalent circuit can be used for calculations.
