5-3. Assume that the field current of the generator in Problem 5-2 is adjusted to achieve rated voltage (480 V) at full load conditions in each of the questions below.
(a) What is the efficiency of the generator at rated load?
(b) What is the voltage regulation of the generator if it is loaded to rated kilovoltamperes with 0.8-PFlagging loads?
(c) What is the voltage regulation of the generator if it is loaded to rated kilovoltamperes with 0.8-PFleading loads?
(d) What is the voltage regulation of the generator if it is loaded to rated kilovoltamperes with unity-power-factor loads?
(e) Use MATLAB to plot the terminal voltage of the generator as a function of load for all three power factors.
