Modular Paralleling Systems
Generac Power Systems has the alternative solution for energy
projects between 300 kW and 6000 kW - the Generac Modular
Paralleling System (MPS). Since large, single engine generators are
very costly and inefficient when not operated at full load, the
lower expense and greater operating flexibility of the Modular
Paralleling System makes it a superior choice for higher kilowatt
applications.
The Modular Paralleling System combines two or more smaller diesel
generator sets in a side-by-side parallel arrangement to achieve a
larger combined power output at a significantly lower cost.
The
purchase price – including Generac’s own fully integrated
paralleling switch technology – is approximately 20 to 30% lower
than large, single engine units (and the actual savings may be even
greater in some cases). Since the modular generators can be operated
singly or in concert with each other, the Generac MPS has unmatched
flexibility and is fully adaptable to lesser loads.
Since the individual gensets being combined can vary in output
rating, the Modular Paralleling System can be more precisely matched
to load requirements, in any increment of 100 kilowatts. To do this,
Generac combines its proven 400, 500, and 600 kilowatt gensets in
varying combinations that cover the entire power range from 800 to
6000 kilowatts, producing 480 Volts AC at 60 Hertz.
Up until now, combining multiple generators was common only with
large megawatt units in premium installations, due to the high cost
of paralleling switchgear. As a vertically integrated manufacturer,
Generac has devoted its energies to breaking the cost barrier in
order to bring this multiple unit paralleling capability to an
entirely new range of applications.
Features and Benefits
The Generac Modular Paralleling System provides reliable standby
paralleling automatically. When an outage occurs, the generators are
started and paralleled together. Then the load is transferred to
them through the Generac transfer switch. During standby operation,
the generators will all operate at the same output percentage to
uniformly share the load, while operating as a single unit with no
reduction in rated power output. Depending upon load requirements,
Generac’s Modular Paralleling System uses two to five generators
operating in parallel.
In terms of dollars per kilowatt, when you look at the cost of
acquiring and operating the Generac Modular Paralleling System
versus large single engine units, you'll see the bottom line
advantages immediately. The benefits of this system include:
 | Lower cost / Quicker payback
— Less expensive acquisition cost and faster recovery of expense
than large single engine generator sets |
| Modular flexibility — The
flexibility to combine two, three, four, or five gensets of the
same or different kilowatt outputs (400, 500 or 600 kW) to more
precisely match load requirements from 800 to 6000 kilowatts |
| Modular design — Modular
commonality of equipment with a lower cost structure and ease of
upgrade to add additional units |
| Ease of installation — The
ability to lift, move, and place the smaller MPS gensets with
conventional forklift trucks instead of heavy cranes |
| Availability — Delivery
within normal lead times, unlike competing large units that are
frequently backlogged |
| Redundancy by design —
Greater power availability and redundancy as units back up each
other, which also provides coverage during maintenance |
| Built-in paralleling capability
— Integrated paralleling equipment built-in to both the design and
the price |
| Reduced maintenance costs
— Serviceable by diesel technicians at lower hourly rates, unlike
larger single engine units requiring more specialized and costly
service |
| Less expensive parts —
Replacement parts less expensive and more commonly available than
for larger single engine units |
| Single source availability
— Single source availability of all components from Generac
|
| Full coverage warranty — A
Generac warranty covering the entire package |
By combining its vertically integrated manufacturing capability,
innovative technical expertise, paralleling switch technology and
proven engine designs, Generac has developed a flexible package that
is readily available. For a wide range of applications ranging from
800 to 6000 kilowatts, the MPS System is a superior alternative that
will do the job, with greater flexibility and less expense.
