a Three-Phase 765-kVm,60Hz, 300-km, completely transposed line has the following positive-sequence impedance and admitance.
z= 0.10144+j0.3281 ohms/hm
y= j3.284x10^-6 S/km
1) Assuming a positive sequence operation, calculate the exact ABCD parameters of the line. Compare the exact B parameter with that of the nominal n circuit. Also compare the equivalent and nominal n circuits for the line.
2) For the same transmision line assume the recieving end, Zr=Zc/3. At the sending end Eg^(t)= Eu-1^(t) and Zg = 2Zc, Plot the Voltage v(1/4,t) versus time t.
