The TechnoCentre éolien has a LIDAR (Light Detection and Ranging) device, a remote measuring tool used to analyse wind profiles by means of a laser beam. Measurements are taken by a three-dimensional conical beam of light; the resulting data serves to analyse wind speed and direction at various heights (from 40 to 200 metres above ground level) and on the entire surface of the rotor.
Operating as a stand-alone device, this tool serves to gather data that can be used many times while developing or operating a wind farm. For instance, the data can be used to evaluate the wind turbine power curve, calculate the impact of thermal effects on energy production, optimise a project's design or conduct analyses at a complex site.
While the use of a measurement mast is still indispensable during the development phase of a wind farm project, LIDAR measurements are often used as a complement to data gathered via a mast, and serve to fine-tune existing data by producing a better understanding of the wind profile in complex areas at a given site. It can be deployed on other sites according to project needs.
