question in answers but withoutpart D, this is my posting the same question 2nd time for partD.
Please don't post the same solution, solve it by yourself withpart D.
Problem 1 [15 points] Consider a three phase 750 kV, 60 Hz, bundle-conductor line with five sub-conductors to each phase is used to feed a three phase distribution system loads operating at 12.5 kV through two transformers. Assume horizontal phase layout with phase spacing D₁= 14 m, bundle separation S 46 cm. Assume that the diameter of each subconductor is 3 cm. The length of the transmission line is 240 km. a. Calculate the inductance in henries per meter per phase. [3 points]. b. If load 1 is a wye connected load which draws 1.3 A at 0.8 pf lagging and voltage of 12.5 kV; determine the real, reactive and apparent power of the load. [3 points]. C. If load 2 is a second load which is delta connected and operates in parallel with Load 1. Load 2 draws 10kW with an adjustable reactive component. What is the power factor of load 2 in order to have an overall unity power factor when the two load currents are combined? [3 points]. d. The above two loads are fed from a salient pole synchronous generator using the above bundle-conductor and two ideal transformers (step up transformer with turns ratio of 500 and step down transformer with turns ratio of 60). Calculate the excitation voltage of the generator to feed the loads by 12.5 kV if the armature resistance of the generator is neglected and the reactances are Xd 12 Ω and Xq 10 Ω. Neglect the resistance of the conductor. Draw a single phase equivalent circuit that shows the overall system. [6 points]. =
