The Fig. 1 shows a double-circuit three-phase 765-kV, 60 Hz, 400-km, on a steel tower completely transposed, symmetrical about both the horizontal and vertical center lines. The 400-km is uncompensated and let the self GMD of a single conductor be 1 cm. The resistance of the transmission is 0.04260 /km and the line is lossless. The sending-end power 1920 MW and 600 MVar are being transmitted at 765 kV at the sending power. Ampacity of conductor is 5000 A. a 7.5 m 4 m b' 10 m 4 m 7.5 m Fig. 1 Set up MATLAB file line_model.m to conduct the following runs on the simulation: Determine the RLC parameters of the line.
