Wind Turbine Solution | Main Power Circuit
Improving your energy harvest
through maximum efficiency
Once your generator has produced electricity,
you want to hold on to as much of that
energy as possible. That’s why it’s so
important that your main power circuit be
reliable, efficient, and designed in accordance
with the relevant standards.
Our products — including the contactor and the
LV circuit breaker — have been designed together
to reach a Type 2 coordination, meaning that if
an overvoltage occurs, one piece of damaged
hardware won’t harm another. And, while
converters are typically a place where energy is
lost, our Xantrex converter —designed specifically
for the wind industry — is very efficient.
But our wind-specific equipment doesn’t stop
there. Our DVCAS switchgears are designed
to fit through doors as small as 600 mm wide,
and can be installed in wind turbines up to
2000 m above sea level. Of course they comply
with all the relevant standards (IEC and UL),
and also meet all the needs of networks up to
36 kV (IEC) / 38 kV (UL).
In addition, our main power circuit solution
will help you:
Achieve better service continuity
and heightened safety with integrated
switchgears and transformer substations.
Lower both your capital and operating
expenses by up to 25 percent through
power factor correction/harmonic mitigation.
Improve your business performance by
reducing downtime and increasing the
lifetime of your equipment.
Setting a new standard for
wind power with Xantrex converters
With more than 20 years of experience in
the wind industry, Xantrex has established
its name as a reliable partner in any wind
project. End-to-end maintenance, support,
and rapid response time have only added
to that reputation.
But the converters themselves are the real
story. Each Xantrex wind power converter
is custom-designed to provide optimum
performance with your specific generator
and is built using proven modular assemblies.
Additionally, to meet stringent utility grid code
requirements worldwide, Xantrex converters
are available with patented technology that
keeps wind turbines connected to the grid,
despite large voltage or frequency variations.
This same technology also reduces torque
stress on turbine gearboxes and drive shafts.
It’s this kind of innovation that has made
Xantrex such a dominant force in the wind
power industry, serving wind turbines from
the 10 kW up to the 5 MW power classes.
Wind-specific products provide
added reliability for your main power circuit.

Wind Turbine Solution | Control of the Wind Turbine
Ensure an optimized
operating environment
Efficiency alone can be the difference
between a successful wind turbine and one
that fails to produce. So, why would you
choose anything but the most efficient
solution for your installation?
Schneider Electric fully automates the
wind turbine, using such products as
the Programmable Logic Controller (PLC) and
a highly-reliable UPS. Together, they form a
dynamic and rugged system which has very
low power consumption, and can be easily
modified or upgraded.
As such, the PLC functions as the “brain” of
the wind turbine, while the UPS provides the
backup power to keep the PLC working — even
when no wind energy is being collected. And
with this integrated system, you also enable:
The ability to gracefully shut down the
wind turbine, distribution and/or collection
monitoring and control systems
The capturing and storing of any information
related to the state or failure of the wind
power system when an outage occurs
Heavy reduction in maintenance
costs, longer mean time between
failure, and simplification of the
troubleshooting process
Enhanced safety for the wind turbine, the
power grid, and any personnel involved
With complete control of the turbine, you finally
get the kind of compact, high-performance
solution that only comes from a provider with
decades of expertise in automation. Finally, you
can optimize your efficiency to get the results
you’ve been looking for.

TeSys U-Line Motor Starter-Controllers:
The ultimate in motor control and protection
There’s never been a motor control system quite like Schneider Electric’s new TeSys U-Line.
With ingenious simplicity, U-Line brings power, protection, and control all together in one
incredibly compact, modular device. In fact, the wind-specific TeSys U — designed to fit
easily into a nacelle — reduces the size of the panel by 40 percent versus the traditional solution.
Because of its simple plug and play modularity, the TeSys U-Line has ten times fewer part numbers
than devices using standard components, so preparation, selection, and ordering are fast and
easy. Additionally, the U-Line requires 80 percent less wiring than a traditional solution, and, in
case of an overload trip, the reset can be done quickly and easily without going up to the nacelle.

Protect your turbines;
connect your wind farm
Optimize equipment safety
and availability through MV Collection
When dealing with more than just a single
turbine, harvested energy must be collected
before it’s brought to the power station.
To do this as safely and efficiency as possible,
wind farm operators need a system for MV
Collection. This includes such equipment as
transformers, switchgears, and kiosks to
name a few.
But what puts Schneider Electric’s solutions
above the competition is the fact that all
these products have been designed to work
together, ensuring electrical, mechanical,
and communication compatibility. And, each
aspect of the solution contributes to the overall
productivity of the wind farm in its own right:
SF6 insulated switchgears that ensure
the electrical installation is optimized,
has improved performance and better
service continuity.
Wind-dedicated transformers that are
highly efficient and proven reliable
against a variety of environmental hazards.
Customized, prefabricated substations
that improve network efficiency and
maximize electricity production.
A complete electrical installation that
allows you to better manage your
maintenance costs.
Also, however, the transformer and the
switchgears have been specifically tailored
to wind farm constraints: while all are especially
compact, the switchgears, for instance, are
purposely designed to be a mere 60 cm,
allowing them to pass through the door of
a wind turbine.
And if you want to ensure that your project
goes smoothly, look no further than our
own Projects and Engineering Centre.
There, we bring more than 50 years of
experience to the table, helping you
develop innovative value proposals using
our cutting edge expertise. To learn more

Achieving improved reliability
and efficiency at once
A solution to connect you to the grid
and extend the life of your equipment
Connecting to the power grid brings with
it a unique set of challenges: surges, dips,
distortions, and, of course, stringent grid code
requirements. Even small shifts of power flows
can trip circuit breakers, sending larger loads
onto neighbouring lines and causing chain
reaction failures.
For those not from electrical backgrounds,
solving these problems can be a daunting
proposition. And yet, bringing clean,
reliable power to your installation is
absolutely necessary.
Fortunately, being the global specialist in
energy management, we at Schneider Electric
have the solution — the solution to relieve
that grid-induced anxiety, bring you the
optimized reliability you need, and
guarantee 99.5 percent availability.
The solution begins with SF6 insulated
metal-enclosed switchgear, which is
designed to ensure maximum safety in
a reduced-space environment. Its design
also ensures that it is unaffected by the
environment, enabling a superior continuity
of service.
In terms of grid code requirements, we design
and provide everything you need to comply,
from fixed LV and MV power factor solutions
to real-time compensation systems. These
systems, which include harmonic mitigation,
provide several benefits that can be translated
directly into financial savings for both the
investor and the user:
Up to 25 percent reduction is commonly
achievable in both capital and
operational expenses
Significant reduction in downtime
Extended equipment lifetime
Minimized system losses
and demand power
Reduced overloading on the electrical
system, thereby releasing useable capacity
All this adds up to improved competitiveness
of your business. And, since such measures
are now all but essential for operating a safe
and successful installation, the time has never
been better to take these precautions against
an unreliable grid.
Bringing clean, reliable power to your
installation is absolutely necessary.
