Question: As a design engineer, you are asked to design a 40Hz, two-conductor transmission line from Muscat to Barka substation. The transmission line delivers the Barka

As a design engineer, you are asked to design a 40Hz, two-conductor transmission line from Muscat to Barka substation. The transmission line delivers the Barka substation with 2500KW, 35KV at 0.85 power factor lagging. The transmission line parameters are 15ohm and 0.0795H. The spacing between the conductors is 4.5cm. Analyze the model of the transmission line and the effect of line constants based on the given data. What will be the effect on voltage and power factor at the Muscat station?

Write your inference about the regulation of the line and the ratio of power at Barka to power at Muscat. It is observed that after every 25km the position of the transmission line is changed. What will be the reason for this? Justify your answer.

Analyze the effect on inductance, if the system is replaced by three-phase conductors with a spacing of 3m,300cm, and 3.5m and the conductor’s thickness is 1.75m.
