Department of Electrical Engineering and Computer Science EEL6208 Advanced Electric Machinery Homework/Project Set No. 2 Problem 1. (1) We have studied the harmonic properties of a 3 phase machine in Topic 8. How about a 5 phase machine? (2) We have studied 3 phase rectifier in Topic 14d. For a 5 phase rectifier, find the relationship between phase voltage and output DC voltage. Confirm your results using SimuLink. Problem 2. Study lecture notes for Topic 12. Use MatLab symbolic toolbox to derive equations in notes “12 a dq Theory for Synchronous Machine with Damper. Problem 3. Design a 3 phase turboalternator with the following specifications: 600 MVA Delta connected 36 kV (terminal voltage) 60 Hz 3600 rpm 2 pole 0.87 pf lagging Maximum allowable rotor peripheral speed 48,000 ft/min for 20% overspeed Directly cooled stator (water) Directly cooled rotor (hydrogen) V fmax = 600 V You can select parameters, such as the number of slots, etc. by yourself.
