the grid is also referred as infinite bus bar in terms of
synchronisation but it also implies fixed voltage,fixed
frequency,phase seuence,phase voltages
infinite bus bars means the whose parameters like voltage,
frquency, phase sequense remains constant even after change
in parameters in the local ckts.
Infinite busbar is a whose parameters like voltage,
frequency and phase sequence remain constanat even change
in the connected load to the infinite busbar.
An infinite bus bar is a parallely connected network of
ALTERNATORS, whose frequency and voltage remains
constantregardless of power drawn or supplied from it.
an infinite bus bar may be treated like a m/c with large
amount of inertia, so that the frequency will not change.
and the voltage and frequency remains unchanged regardless
of the equipment connected to it.
infinite busbar concept refers to a rigid network where the
frequency of the supply and its voltage remains unchanged
irrespective of the direction of power flow from one node
to other.
