Homework Statement
A 230kV, 160km long transmission line has the following parameters expressed on a 230kV, 100MVA base.
R = 0.0151
X = 0.1476
Y = 0.288
The sending end voltage of the line is held constant at 1.0 pu. The load at the receiving end has a lagging power factor of 0.8.
Show that the Thevenin equivalent yields,
[tex]V_{Th} = 1.022 \angle -0.13^{\circ}[/tex]
[tex]Z_{Th} = 0.0158 + j0.15077[/tex]
Homework Equations
The Attempt at a Solution
See figure attached for my attempt.
I'm confused regarding the maximum real power transfer limit.
Is this supposed to be calculated assuming,
[tex]Z_{load} = Z_{Th}^{*}[/tex]
or are we supposed to use the PF of the load stated in the question somehow?
Thanks again!
