Meteodyn WT
Meteodyn WT is a Computational Fluid Dynamics (CFD) software for numerical wind simulation and wind resource assessment. It computes all the wind characteristics and estimates the annual energy production (AEP) of wind farms. The results are accurate and reliable, even in complex terrain such as wooded or mountainous areas. It incorporates the latest IEC industry standards and addresses the different phases of a wind power project.
The most powerful CFD software for wind resource assessment
To model the wind and accurately estimate the wind resource, our wind energy software uses Computational Fluid Dynamics (CFD) technology, which has been in use at Meteodyn since 2003. The results obtained are fast and accurate, thanks to the physical models of forests and atmospheric boundary layer, and the self-convergence algorithms implemented.
Meteodyn WT is suitable for both beginners and experts in numerical simulation who want to perform wind resource and energy yield assessment studies.
Wind farm design and planning
Annual energy production (AEP) computation
The Annual Energy Production (AEP) computation can be performed by weighting the wind speed distribution at the rotor height with the power curve of the wind turbine (REWS), taking into account losses due to wake effects.
Determination of atmospheric stability
Using only temperature and wind speed measurements, Meteodyn WT automatically determines the appropriate atmospheric stability class for each time step in a time series.
Full compliance with the IEC 61400 standard
Meteodyn WT provides the wind characteristics at the future wind turbines location. These elements determine the choice of wind turbine class, which must meet minimum design requirements to ensure structural integrity (IEC 61400-1).
Meso-microscale coupling
To accurately model wind characteristics at large sites, it is necessary to couple local characteristics with regional climatic effects. Our meso-microscale coupling method has achieved a wind speed bias of less than 1%.
Multi-mast tool
Allows the use of multiple measurement masts, lidars and/or sodars as input to the synthesis to calculate the wind turbine power output. The confidence placed in each of them can be configured. This feature is useful when multiple sources of meteorological measurements are available at the wind site over similar time periods.
Full integration of mesoscale data into microscale computations
Microscale wind simulations consider the thermal stability of the atmospheric boundary layer through turbulent mixture. To account for thermal effects over large computational domains, it is necessary to integrate wind data from mesoscale simulations. Meteodyn WT assimilates wind data from a grid of mesoscale points as climatological synthesis input.
Accurate and reliable wind resource assessment
The economic viability of a wind farm is secured by an accurate wind resource assessment and the proper analysis of wind characteristics.
Meteodyn WT computes:
- The wind speed and direction ;
- The energy density and the AEP ;
- The wind angle of incidence ;
- The wind shear ;
- The wind vertical profile ;
- The 50-year extreme wind ;
- The turbulence intensity.
Roughness and orography overlay
If the user’s field data is incomplete, it can be supplemented with the roughness and orography (topography, elevation, etc.) data provided in Meteodyn WT to launch CFD calculations.
