Transcribed Image Text:

The Fig. 1 shows a three-phase 69-kV, 60 Hz, 300-km, on a steel tower completely transposed, has stranded conductors per phase, symmetrical about both the horizontal and vertical center lines. Each strand has a radius of 4 cm. The line spacing is measured from the center of a strand. The resistance of the transmission line is 2.84x10* 2-m and the line is lossless. The line delivers 70 MVA, 0.8 power factor lagging and at 64 kV. b 14 m 14 m Fig. 1 ETAP Simulator Using Actual Transmission Line Parameters. The receiving-end power is 70 MW at 0.8 power factor lagging and at 64 kV. Use the self GMD of a single conductor determined above in the computation. 2. 1. Determine the RLC (given above) parameters of the transmission line per km. Set up ETAP file line_modell.oti to conduct the following runs on the simulation: (i) Determine the sending-end phase voltage, sending-end line current, sending- end complex power, power factor, and the percent voltage regulation. Keep the phase angle of the receiving-end voltage at 1.0/0° p.u. (ii) Determine the sending-end phase voltage, sending-end line current, sending- end phase complex power, and power factor.
