Question 2 In PowerWorld Simulator case Problem 2_32see Figure 1)a 8 MW and 4 Mvar load is supplied at 13.8 kv through a feeder with an impedance of 1 + 2 . The load is compensated with a capacitor whose output. Quas, can be varied in 0.5 Mvar steps between 0 and 10.0 Mars. Source Voltage = 14.98 kv Feeder Impedance 1 + 2 Ohms Power into Feeder at Source 9.42 MM 4.84 Mvar 9.71 MVA 13.80 kv Feeder Losses = 0.420 MM 0.840 Mvar B. 4.0 Mar 0.0 var Figure 1 21 Draw a table recording the following parameters as Qop is varied in 0.5 Mvar steps from O and 10.0 Mvars - Real power feeder losses in MW. - Reactive power feeder losses in Mvar. . Real power into feeder at source in MW. - Reactive power into feeder at source in Mvar. - Apparent power into feeder at source in MVA . Source voltage in kv. (12) (5) (2) (5) (2) 22 From the data in the table you have drawn in 2.1, plot a line graph of real power feeder losses in MW as a function of Qasin Mvars. 23 What value of Qc minimizes the real power line losses? 2.4From the data in the table you have drawn in 2.1, plot a line graph of apparent power into feeder at source in MVA as a functionof Qap 2.5What value of Q.cu, minimizes the MVA power flow into the feeder? 2.6Assuming that half the time the load is 10 MW and 5 Mvar, and for the other half Is 20 MW and 10 Mvar. What single value of Qap minimizes the average real power line losses? Assume that can only be varied in 0.5 Mvar steps Note: Draw a table recording real power losses in MW as Quep is varied from o Mar to 10 Mvar firstly with the load foed at 10 MW and Mear and then, with the load fixed at 20 MW and 10 Mvar. In your table add a column recording the average real power losses (between high and low load) for each step of Qas. Determine the answer.) 2.7What is the relationship between direction of reactive power flow from the source to the load and the voltage magnitude at the source and the load. At what point (10) 2 in relation to voltage magnitudes at the two buses) does the reactive power flow in the feeder reverse as you vary Q12)
