At full load the line in Problem 5.14 delivers 1000 M W 1000 M W at unity

Question:

At full load the line in Problem 5.14 delivers $1000 M W$ at unity power factor and at $475 k V$ . Calculate: (a) the sending-end voltage, (b) the sending-end current, (c) the sending-end power factor, (d) the full-load line losses, and (e) the percent voltage regulation.

Data From Problem 5.14:-

A $400 - k m, 500 - k V, 60 - H z$ uncompensated three-phase line has a positive-sequence series impedance $z = 0.03 + j 0.35 Ω / k m$ and a positive-sequence shunt admittance $y = j 4.4 \times 10^{- 6} S / k m$ . Calculate: (a) $Z_{c}$ , (b) $(γ l)$ , and (c) the exact $A B C D$ parameters for this line.
