I have just started my first Semester (Fall 2021) out of 4 semesters in Master of Applied Science (M.A.S) in Power Engineering at Illinois Institute of Technology. I did not clearly undersand the course enrollment system because I am new to the system, so I ended up enrolling in courses; ECE58-Microgrid Design and Operation, and ECE579-Computer Aided Design of Electrical Machines. It appears ECE582 listed ECE418 (Power System Analysis) as a prerequisite; and ECE539 requires ECE319 (Fundamentals of Power Engineering) and ECE412(Hybrid Electric Vehicle Drives) as prerequisites. Let me hasten to add that I graduated in 2009 in a different academic setup in Africa in Electrical Engineering. So, not only do I have to cover the gap of about 12 year out of classroom, but I have compounded the problem by jumping into advanced courses before enrolling into foundation courses. Unfortunately I can no longer switch courses as the enrollment window has passed. I am only left with one option; to…

A single phase distributor 1 km long supplies a load of 100A at 0.8 p.f. lagging at its far end and a load of 200A at unity p.f. at its mid-point. Both power factors are referred to the voltage at the far end. The resistance and reactance per km (go and return) are 0.1 Ω and 0.2Ω respectively. If the voltage at the far end is maintained at 200V, calculate feeder current, voltage at the sending end . Also find phase angle between voltages at mid-point and sending end.
