Generators in parallel with other
generators of the same size
When a generator is working alone, its real and reactive power are fixed and
determined by the load.
When a generator is connected to an infinite bus, its frequency and the terminal
voltage are constant and determined by a bus.
When two generators of the same size
are connected to the same load, the
sum of the real and reactive powers
supplied by the two generators must
equal the real and reactive powers
demanded by the load:
