Rework Example 14.3 with R Load = 40 / R Load = 40 / phase,
Question:
Rework Example 14.3 with phase, phase, and phase.
Example 14.3
Figure 14.21 shows a single-line diagram of a primary feeder supplying power to a load at the end of the feeder. A shunt capacitor bank is located at the load bus. Assume that the voltage at the sending end of the feeder is above rated and that the load is Y-connected with phase in parallel with load /phase.
(a) With the shunt capacitor bank out of service, calculate the following: (1) line current; (2) voltage drop across the line; (3) load voltage; (4) real and reactive power delivered to the load; (5) load power factor; (6) real and reactive line losses; and (7) real power, reactive power, and apparent power delivered by the distribution substation.
(b) The capacitor bank is Y-connected with a reactance phase. With the shunt capacitor bank in service, redo the calculations. Also calculate the reactive power supplied by the capacitor bank.
(c) Compare the results of (a) and (b).
