A 3-phase, 400-km line delivers rated power to a 480 MVA t 0.82 pf lag load @ 345kV. The line has a series impedance 0.4<(80°)transfer parameters are : A=D=0.87; B=j150 & C=j0.0016.
a). Calculate the sending and voltage , current and voltage regulation and P(max).
b) A series capacitor providing 60% compensation is installed on the line. Using lossless line approximation, calculate the new A& B constants ; the sending end voltage, current, voltage regulation & P(max).
