A 400-km long lossless delivering 600 MVA to a load at 345 KV, 0.8 pf lag. The line transfer parameters are : A=D=0.9; B=j200 & C=j0.002.
a0. Calculate the sending and voltage , current and voltage regulation. using the line loadability equation, calculate the line surge impedance loading ' SIL" and the normal operating voltage ( assume d=40).
