See all publicationsIEC 61400-50-3 – compliant wind speed measurements with a ZX TM nacelle-mounted lidar: A case study in uncertainty analysis
PO.181 - WindEurope Conference, Bilbao 2024
An IEC- compliant assessment of ZX TM nacelle-mounted lidar measurements has been reported by DNV (1), following the IEC 61400-5-3 standard (2). Here we present a thorough case study deriving uncertainties for hub-height horizontal wind-speed (HWS) measurements made by a ZX TM on a 3 MW turbine in central USA.
Data-driven approach to the design and implementation of retrofit lidar assisted control
PO.187 - WindEurope Conference, Bilbao 2024
We demonstrate load reduction using lidar assisted control using a feedforward/feedback controller and a simplified lidar system. This solution was retro-fitted to a commercially operating wind turbine. Complex aeroelastic wind turbine models were unavailable and the through life cost of the lidar control system was targeted.
Tower fore-aft bending and blade flap edgewise moments were significantly and safely reduced without negative effects on AEP. The methods and technology applied provide an opportunity to reduce the LCOE of current and future turbines.
Can we bank on wind Lidar?
In November 2014 we asked the industry ‘can we bank on wind Lidar’? Can we use it to provide quantitative data for the annual energy prediction
of a wind farm, allowing developers to raise or ratify the necessary finance to progress and construct full-scale developments? Today, in 2022, that
question has not only been answered, spoiler alert: it’s a ‘yes’, but the industry is now not just ‘banking’ on it, it is ‘relying’ on it.
First things first with wind measurement - PES article
The role of lidar within wind measurement campaigns is routinely documented in wind energy publications, conferences, and in important, fundamental academic research. Often, the focus is on the types of and use of measurements/data that wind lidars offer. Sometimes overlooked is the ability to deploy lidar at speed; not only once on site, practically, due to the sensor itself being remote, i.e. at ground level, from the target, i.e. the wind, but actually often without the need for any planning permission whatsoever.
