Problem Summary The power factor of a network is a measure of how efficiently the power is used and power factor correction is technology and equipment used to ensure this is as efficient as possible. Power factor correction is the process of increasing the power factor without altering the original load. Problem Description Figure I shows a three-phase generator feeding a load through a feeder. Given: valt) = 312 cos 377t, vy(t) = 312 cos(377t + 120°), ve(t) = 312 cos(377t + 240°) R = 42,12 = 10 mH, R = 152, L = 0.25 H A capacitor bank connected in Delta is added to improve the power factor of the load. 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.
