Electric Power and Machines

A three-phase, 60 Hz, 8 pole, 40 MVA, 14 kV synchronous generator has negligible armature resistance. Test data for the generator is presented graphically below, and curve fit expressions for occ and scc have been provided. The rotational losses of the generator are 2 MW.

ISC = 7If

VL (OC) = 21300If/430 + If

Use any computational resources at your disposal to determine the true operating point (required field current) of the machine if it is supplying a 35 MW load at 0.97 pf lagging and 13.8 kV. You should employ an iterative solution, and you should do sufficient work and documentation of your code or other form of solution methodology that your solution may be adequately validated.
