General
Under balanced and stable conditions, a generator operates with a constant rotor
angle (power angle), delivering active electrical power to the power system, which
is approximately equal to the input mechanical power on the generator axis.The
currents and voltages are constant and stable. An out-of-step condition is
characterized by periodic changes in the rotor angle, that leads to a wild flow of the
synchronizing power; so there are also periodic changes of rotational speed,
currents and voltages. When displayed in the complex impedance plane, these
changes are characterized by a cyclic change in the complex load impedance Z(R,
X) as measured at the terminals of the generator, or at the location of the
