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.

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.
