NRG introduces new windpower data device

HINESBURG-NRG Systems, leading manufacturer of wind measurement equipment, and Leosphere, leading specialist in lidar for atmospheric observations, announced the introduction of the WINDCUBE(r) v2, the lightest, most compact lidar remote sensor available.

Used in site assessment and wind farm performance monitoring, the WINDCUBE v2 collects actual measurements at heights up to 200 meters, mapping the vertical wind component, wind speed and direction, turbulence, and wind shear. There will be ongoing live demonstrations of the WINDCUBE v2 at the outdoor venue throughout the American Wind Energy Association's 2010 Windpower Conference & Exhibition in Dallas, Texas.

"Lidar has quickly become the must-have tool in resource assessment," said Alex Sauvage, president and CEO of Leosphere. "Over the past year, our two companies have worked tirelessly to enhance the portability and durability of our lidar remote sensor, making it ideal for complex terrain, remote locations, and offshore."

Weighing 45 kg and measuring approximately 55 cm square, the WINDCUBE v2 features no internal moving parts, multiple communications options (including satellite), low power requirements (45 watts), and an all-weather enclosure. The quiet, ultra portable 200m wind profiler includes ten programmable measurement heights, providing ready-to-use data.

"By collecting actual measurements of the entire swept area of the wind turbine, the v2 improves data accuracy and reduces overall uncertainty of the wind farm design," said John Norton, chief operating officer for NRG Systems. "Improved certainty can make the difference between project success or failure."

The v2 is an active remote sensor that operates by emitting a laser pulse through the atmosphere. Along its path, the laser light is backscattered by aerosols in the air and received by an optical sensor in the lidar unit. These signals capture the shift in atmospheric particles, or the absolute wind speed in the lidar line of sight.

In March 2009, Leosphere and NRG Systems formed a global joint venture to expand the use of remote sensing with lidar in the wind energy industry. The WINDCUBE v2 is the second product of the partnership, built upon the original WINDCUBE which is now operating in 20 countries around the world. The joint venture serves customers on all seven continents with sales, service, technical expertise, and support.
