Unformatted text preview: 1) Calculate the per-unit values of the line impedance, load impedance, and load end voltage; (4 pts) 2) Sketch the per-phase per-unit equivalent circuit of this power system; (1 pts) 3) Calculate the power factor of the system; (2 pts) 4) Calculate the efficiency of the system; (2 pts) 5) If you are asked to increase the load side power factor to 1 by adding an additional component in parallel with the existing load in the circuit you sketched in 2), what component would it be? a) Sketch your new circuit; and b) Show the calculations of the value of the additional component. (4 pts) Assume the system frequency is 60 Hz ....
