If the phase parameters for this 50Hz, 40km transmission line are R=2, L=10mH, and C=8000uF. The line supplies a 120MW load at 132kV and 0.85

If the phase parameters for this 50Hz, 40km transmission line are R=2Ω, L=10mH, and C=8000uF. The line supplies a 120MW load at 132kV and 0.85 power factor lagging.

a) Determine the ABCD constants for the line by using nominal T-circuit representation 

b) Calculate the supply side voltage, current and power factor
c) Elaborate how the ABCD parameters applied to the OHL transmission in various cases.  (i.e. type / length of transmission network)
