Unformatted text preview: goal/5K ﬂaﬂ 020m My / 55.5.14 7/0A/ Design Project Technical Details Example 3-bus system Source deﬁnition: Inﬁnite bus, voltage at 1 per unit, cail this bus “D" 22.86 kV, phase-to-phase 10 mile distribution line, with one bus partway along the line. and another bus at the end of the line (two line sections in series). 4?? AAC “Cosmos" phase conductors (R=0.2159 ohmslmile at 50 deg C. GMR = 0.025 feet) 110 AAAC neutral conductor Construction type: “delta" type construction: diagonal distance from top phase to each outside phase is 34.5”, and distance from outside phase to other outside phase is 43”. Busses modeled along the distribution line: at bus "D” (source). bus "E" (3.0 miles from source). and bus “F" (10.0 miles from source) Load modeled at bus “F": constant current load. 180 amps per phase, 0.341 tagging power factor Assumed voltage at bus “D”: 1.000 p.u. at zero degrees Assumed voltage at bus "E”: 0.950 p.u. at -2.00 degrees Assumed voltage at bus “P": 0.902 p.u. at -4.16 degrees Load modeled at bus “E": constrained from above assumptions, therefore can be calculated from above assumptions. All calculations to be performed to 4 signiﬁcant digits for magnitudes and 4 signiﬁcant digits for angles. ECE 75/ .

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

Dana University of Pennsylvania ‘17, Course Hero Intern

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
