A Comparison of Remote Sensing Device Performance at Rotsea

In June 2010, RES had the opportunity to locate both a Lidar and Sodar remote sensing device at its Rotsea site. This opportunity provided a four week window where data were simultaneously available from each of the M345 - fixed mast, the M808 - Triton (SoDAR device by SecondWind) and the M809 - WINDCUBE (Lidar device by LEOSPHERE).

Assessment of the Repeatability and Stability of Windcube Performances

A recent study of 595 Windcube Lidar validation “couplings” compared Lidar precision and accuracy from the time of manufacture to times when the Lidar was returned to Leosphere years later for maintenance. The findings are outlined in this paper.

Characterization + Classification of the Class 1 Anemometer for IEC 61400‐12‐1 Compliance

This white paper documents the results and supporting work to characterize and classify the Class 1 Anemometer according to the guidelines documented in the DTU Wind Energy Department’s Accuwind reports and the IEC 61400‐12‐1 Standard.

Commercial Lidar Profilers for Wind Energy: A Comparative Guide

The object of this paper is to illuminate the two contrasting and in many ways complimentary designs.

Comparison of Lidars, German Test Station for Remote Sensing Devices

The German Test Station for Remote Wind Sensing Devices has been initiated in order to provide the wind industry the possibility to have tested Lidars or Sodars prior to the application in the field, similar to cup anemometer calibrations.

Direct Lidar Measurement in Complex Terrain

Leosphere, EWEA 2012

In the context of the constant aim to reduce wind farm project uncertainties, remote sensors are gaining attraction because they have the ability to measure up and even above the turbine's hub height and can easily be moved to measure at several locations of the project site.

GL GH Position Statement on the WINDCUBE Remote Sensing Device

Improved Bankability: The Ecofys position on Lidar use

A key goal of a wind measurement campaign is to reduce project uncertainty, as this will improve bankability in terms of better financing terms and reduced project risks.

In Situ and Remotely-Sensed Mean and Turbulence Characteristics of Wind Turbine Wakes

Objective: Collect in situ measurements of ε downwind of a multi-MW turbine for comparison to remotely-sensed quantities and improvement of turbine wake parameterizations.

Lidar Measurement in Extreme Winter Conditions

This poster shows the latest advanced developments towards the improvement of Lidar performance in sites with extreme low aerosol concentration, by comparing simulated and real measurements done during a winter in Finland at a VTT test site.
