Question

A 50-Hz, two-pole, 825 kVA, 2300 V, three-phase synchronous machine has a synchronous reactance of 7.47 and achieves rated open-circuit terminal voltage at a field current of 147 A.

c. For a constant load power of 700 kW, write a MATLAB script to plot the terminal current as a function of field current. For your plot, let the field current vary between a minimum value corresponding to a machine loading of 825 kVA, leading power factor, and a maximum value corresponding to a machine loading of 825 kVA, lagging power factor. What value of field current produces the minimum terminal current?
