AREVA T&D

Onshore Wind Farm Solutions Proven Reliable Tailored

As the Wind Blows, Power Flows Wind – an infinite source of energy that society is harnessing more and more. Wind generated energy is forecast to increase from 200 TWh in 2007 to 500 TWh in 2012.

Wind power, now a mainstream energy technology, benefits people and society at large. It plays a pivotal role in combating climate change and reducing our fossil fuel dependence.

Wind farms - to correctly integrate into the network - require the right equipment and compliance with stringent grid codes. As cutting-edge equipment is critical to power generation from wind farms, operators need the skills and experience of AREVA T&D, a world leader in electricity transmission and distribution.

Substation and Grid Management

AREVA T&D is a world leader providing complete protection and control systems for wind farm electrical networks. They range from electrical protection relays in the substation and the turbine switchgear through to bay controllers, gateways and all the necessary control and configuration software tools.

AREVA T&D offers the latest SCADA and generation management systems for wind farms. They feature a state- of-the-art user interface plus interfaces to wind forecast applications, including portfolio management capabilities.

Optimizing reactive power compensation and harmonic filtering for wind farms includes physical grid connection and grid code requirements. It is crucial to analyze the wind farm installation and grid dynamics at the interconnection point prior to designing the reactive power compensation and harmonic filtering system. Our expert consultants and engineers provide power systems analysis and design for planning and grid connection of wind farms.

Reactive power and harmonics are the most important pa-rameters for grid owners, while frequency range, voltage unbalance and voltage range are the primary parameters influencing wind turbine operation. On the other hand, real power loss optimization inside the wind farm is critical to developers and owners.

AREVA T&D provides turnkey solutions to satisfy these re-quirements. Our range of services includes initial feasibility studies, load surveys, system modeling, design, manufac-ture, installation and commissioning. Our products include low and high voltage capacitor banks, reactors and SVC MaxSine solutions.
