For the circuit shown in Fig representing a feeder connecting a substation and a load, the substation's voltage is fixed at 1 pu 0 degree (V = 1/0). The feeder's impedance is 0.2 + j0.2 pu. Ask: 1) What is the maximum loading PL for a resistive load (i.e., QL = 0)? 2) What is the maximum loading the power factor of the load is fixed at 0.85 (i.e., L 1-0.852 ). 3) Please show two PV curves with V in the vertical axis and PL in the horizontal axis for the two scenarios (resistive load and inductive load). 0.85 = R jx Opinto O+ mm.
