togahockey15

1. The problem statement, all variables and given/known data
Design a dc transmission line that can transmit 225 MW of electricity 185 km with
only a 2.0% loss. The wires are to be made of aluminum and the voltage is 660 kV.


2. Relevant equations
P= IV = I^2 * R
R= p(L/A)
Power loss = Pf - Pi
