Unformatted text preview: EE 387 Homework 02 Fall 2008 Due on Thur. Sept. 11 at the EE Homework Slot outside of 121 EE East before 4:30 p.m. 1. Derive the phase admittance matrix for the floating wye-connected load on Slide 15 of the “polyphase networks” lecture notes by simplify the phase admittance matrix for the grounded wye on Slide 14. 2. Derive the phase admittance matrix for the floating wye-connected load on Slide 15 of the “polyphase networks” lecture notes by applying the technique used to derive the phase admittance matrix for the grounded wye. 3. A 345-kV, 3-phase transmission line delivers 100 MVA, 0.866 lagging, to a wye- connected load. Calculate the following: a. The total real and reactive power delivered to the load. b. The real and reactive power per phase. c. The phase voltages. d. The phase currents. e. The phase impedances. f. The line currents. 4. Repeat Problem 3 for a delta-connected load....
