<span>Most forms of uninterruptible power supply
(UPS) can be either powered by battery or flywheel energy. These are ready for
immediate use at the instant that the mains electricity fails, but the small
amount of stored energy they contain makes them suitable for a few seconds or
minutes of use only. To get uninterruptible and continuous power supply, a
diesel-generator back-up system is needed.</span>

<p class="MsoNormal">
<span>Diesel rotary uninterruptible power supply
devices (DRUPS) combine the functionality of a battery-powered or
flywheel-powered UPS and a diesel generator. When mains electricity supply is
within specification, an electrical generator with a mass functions as motor to
store kinetic energy in an electro-mechanical flywheel. In combination with a
reactor or choke coil, the electrical generator also works as active filter for
all sorts of power quality problems, like harmonics, RFI, and frequency
variations. When mains electricity supply fails, stored energy in the flywheel
is released to drive the electrical generator, which continues to supply power
without interruption. At the same time (or with some delay, for example 2 to 11
seconds, to prevent the diesel engine from starting at every incident), the
diesel engine takes over from the flywheel to drive the electrical generator to
make the electricity required. The electro-magnetic flywheel can continue to
support the diesel generator in order to keep a stable output frequency.
Typically a DRUPS will have enough fuel to power the load for days or even
weeks in the event of failure of the mains electricity supply.</span>

<p class="MsoNormal">
<span>The main advantages of DRUPS equipment
compared to battery-powered UPS combined with a diesel-generator are the higher
overall system energy efficiency, smaller footprint, use of fewer components,
longer technical lifetime (no use of power electronics) and the fact it does
not result in chemical waste (no use of batteries).</span>
</p>
<p class="MsoNormal">
<span>&nbsp;</span>
</p>
<p class="MsoNormal">
<span>The main disadvantages of DRUPS equipment
are a more frequent maintenance regimen due to the number of moving parts.[1]
DRUPS are also typically installed in external buildings due to noise concerns
from the generators.</span>
</p>
<p class="MsoNormal">
<span>&nbsp;</span>
</p>
<p class="MsoNormal">
<span>A DRUPS can provide a ride-through time of
15–40 seconds. A flywheel UPS can be installed ahead of typical UPS battery
systems to reduce the effects of lightning &amp; switching transients and to increase
battery life.</span>
