long-line model

Repeat Problem 4.8 using the short-line model.

Problem 4.8

The 138-kV 3∅ line described in Problem 4.1 is 150 mi long and is delivering 15 MW at 132 kV at a 100% power factor. Find the sending-end voltage and current, the power  and the transmission efficiency. Use the long-line model.

Problem 4.1

Given a 138-kV three-phase line with series impedance z = 0.17 + j0.79Ω/mi and shunt admittance y = j 5.4 X 10-6 mho/mi, find the characteristic impedance Z" the propagation constant y, the attenuation constant γ, and the phase constant β.
