What are the main components of the solar water pumps, briefly explain each component. Comment on the Air University electric bill saving if the water pumps are transferred from WAPDA to solar systems. (h) Air university water pumps data and pumping capacity is also give. (e) Find the rate of kwh and determine the savings in electric bill. Also calculate the reactive power supplied by the capacitor bank (c) Compare the results of (a) and (b). With the shunt capacitor bank in service, redo the calculations. (b) The capacitor bank is Y connected with a reactance X=400/phase. (a) With the shunt capacitor bank out of service, calculate the following: (i) line current (ii) voltage drop across the line: (iii) load voltage: (iv) real and reactive power delivered to the load (V) load power factor, (vi) real and reactive line losses and (vii) real power, reactive power, and apparent power delivered by the distribution substation. Assume that the voltage at the sending end of the feeder is 5% above rated and that the load is Y-connected with R=200/phase in parallel with load X.j40/phase. A shunt capacitor bank is located at the load bus. ![]() ![]() Shunt Capacitors in Air University Distribution Systems Shunt Capacitor Bank at End of Primary Feeder Figure: shows a single-line diagram of an 11-kV primary feeder supplying power to a load in Air University at the end of the feeder. ![]()
