Denmark’s DONG Energy has chosen SmartWind Technologies to supply what it is calling ‘a game-changing’ dual-doppler radar system for offshore wind measurement.
Two radar units will be installed in 2016 on the UK east coast near the Westermost Rough Offshore Wind Farm which is currently under construction. They will produce high-resolution dynamic maps of the wind flow through and around the wind farm.
The 18-month measurement campaign – the first of its kind where radar will be used for offshore wind measurement – will focus on wind farm wakes, power curve measurements and wind turbine load validation. The campaign is part of DONG Energy’s BEACon – Beamed Radar for Energy Assessment and Site Conditions – research and development project. The project team will be responsible for running the test and demonstrating the new radars.
Nicolai Gayle Nygaard, BEACon Technical Manager in DONG Energy, explained: ” Contrary to standard measurement set-ups, such as a met mast or a profiling lidar which provide measurements of the wind speed and direction at a single position, the radars give us the ability to quickly scan the flow field in and around an entire wind farm with unprecedented range and resolution.
Nygaard continued: “This enables a paradigm shift in the approach to integrating wind measurements into the design and operation of offshore wind farms. Project BEACon will give us invaluable new knowledge which can be applied across our entire portfolio to lower the cost of electricity.”
When developing new offshore wind farms, wind data is one of the key drivers of the layout. Besides their impact on the wind farm production the wind conditions also influence the capital expenditure through the foundation design. With the wind data from the BEACon project DONG Energy will be able to refine the assumptions and models used in optimising wind farm layouts and in the design of turbine foundations.
