Three-phase transmission line has ABCD constants as shown below. The line is 80 km long. A = 0.995120.0313 B=36.22483.66 2 C=0.00027490 S Using the nominal a model and line ABCD constants, calculate the sending end voltage and current, voltage regulation, the receiving end reactive power, the sending end active and reactive power, and the transmission efficiency when the line delivers 160 MW, 0.8 lagging power factor at 220 kV.
