Meteodyn joins the CLS group

Meteodyn joins the CLS group

At Meteodyn, our expertise in wind engineering, meteorology, and climatology allows us to support our customers and partners internationally since 2003 in the sectors of renewable energy, urban planning, and wind safety. Today, it is our pleasure to announce that we have joined the CLS group since October 1, 2021. CLS is a subsidiary of the CNES (The French Space Agency) and of the CNP, pioneer provider of monitoring and surveillance solutions for the Earth since 1986.

The ALEX17 benchmark: WRF-Meteodyn WT’s wind speed BIAS lower than 1%, with less than 2 hours computing time

The ALEX17 diurnal cycles in complex terrain benchmark (J. Sanz Rodrigo et al 2021 J. Phys.: Conf. Ser. 1934 012002) was the last experiment within the New European Wind Atlas (NEWA) project. Its objective was to identify the wind conditions upstream of the Alaiz Site in order to validate flow models. The site in question is a complex terrain one located near Pamplona, Spain. An elevation map of the site is displayed in figure 1. This benchmark was intended for flow models that can...

Terrain types in IEC TR61400-12-4 standard

The new IEC TR 61400-12-4 standard: improvement of numerical flow modeling

Since June 2016, Meteodyn collaborated with other firms on the development of this new IEC standard. Intitled “Numerical site calibration for power performance testing of wind turbines”, this new standard is part 12-4 of the TC 88 – Wind energy generation systems. Finally, after 4 years of work, verification, validation and deliberation, the IEC standard has been published in September 2020. Bringing together the latest advances in numerical flow modeling, its aim is to improve the...

Multimast tool in Meteodyn WT

Meteodyn WT - The multi-mast tool

The multi-mast tool is available in the synthesis section of the Meteodyn WT Software. It enables the use of several measurement masts and/or several LiDARS as input to the synthesis. The objective of the Synthesis is to automatically calculate the output of wind turbines as well as all wind characteristics for a site from the following: - The results of directional CFD calculations carried out previously. - The power and thrust curves of each wind turbine. - The meteorological data. The...
