Q1: A 3-ph, 50 Hz, 150 km length O.H.T.L. supplies a load with P MW load at 0.85 lag P.f. and 69 kV where P is the last two digits (from right) of your registration number (i.e for the student that has a registration number 202112396, P = 96). . This T.L has a resistance of 0.232 /km and an inductive reactance of 0.783 Q/km and the capacitance to neutral is 0.0446 µF/km. Using nominal a circuit, Find: 1- Constants A, B, C, and D. 4- Voltage regulation of this T.L. 5- Transmission line efficiency. 6- Draw with a scale the phasor diagram of this model at this operating case. 7- Estimate approximately the loadability of this transmission line at this operating voltage. Justify your estimation and suggest a way to increase this loadability. Verify your answer. 2- Sending end voltage. 3- Sending end current
