Paralleling switchgear for standby power systems is becoming
more popular these days because of the introduction of sophisticated integrated
digital control technologies that offer advantages to a wide range of
installations, including healthcare facilities, data centers and other facilities
where uninterrupted power is critical.
Digital control technologies make it easier to operate
systems in parallel and enable running multiple smaller generators rather than
one large generator to supply power when utility power fails. Advantages of
installing multiple generators and paralleling switchgear include the ability
to build in redundancy for increased reliability for critical loads and
scalability as facility needs expand.
With integrated paralleling system, if one generator fails,
the other generator can handle the most critical loads, shedding the
non-critical loads. If the facility had only one generator and it failed, there
would be no power for the critical load. This is redundancy that makes for
greater reliability of power.
Some systems include high end capabilities in mid-range
solutions. For instance, paralleling switchgear can include monitoring and
control that is completely independent of the operator touch screen and
generator control that is completely independent from the master controller.
What is your experience with paralleling switchgear? If not yet using it, is it
under consideration?
