This example investigates the voltage versus current
characteristic of an uncontrolled electrically excited synchronous
generator operated at different loads. In each load case the phase
angle phi
of the load impedance is kept constant, but
the magnitude of the impedance is varied logarithmic. The generator
is driven with constant speed.
The intention is to compare the results of the following simulation models in one plot:
phi = -45°
(capacitive)
phi = -30°
(capacitive)
phi = 0°
(ohmic)
phi = +30°
(inductive)
phi = +45°
