Accurate and detailed knowledge of the wind characteristics is the most important aspect to develop a successful wind project. The knowledge is essential in all stages of the wind farm development process, from the design of the first layout to the selection of the most suitable wind turbine.

The aim is to obtain high quality measurements which will allow reducing the uncertainties of the energy assessment of the projects and so helping a better financing of the projects.

IESBG plans wind assessments to best adapt it to the individual project. Our experienced experts take care of the data and analysis of the wind measurements based on both wind measurement and a deep knowledge of the theory of the fluid dynamics. Our broad experience covers all phases of the wind resource assessment process in simple or complex environments.

  The most essential matter to develop a successful wind farm project is the development and implementation of the most suitable monitoring strategy and  include:

- Selection of the best mast locations on the site – compliance with the investor’s strategy and determining the best mast locations depending on the terrain, relief, wind obstacles, different limitations (roads, grid, populated areas, etc.)

- Mast configuration - (sturdiness, design, height, sensor location, loggers, boom lengths, standing rigging, etc.) in compliance with the standard IEC61400-12-1 and recommendation No. 11 of IEA (Recommended practices for wind turbine testing and evaluation №11. Wind speed measurement and use of cup anemometry). Selection of the most suitable masts, available on the market, in terms of technical characteristics, weather resistance, local climate in the project region, etc.

- Expert assistance in the sensor selection – quality, price, stability, calibration, etc.

SODAR campaigns

IESBG skills extend also to advanced wind measurement services such as the application of SODAR to study the 3-D boundary layer, turbulence and wake effects. The technology and the devices are also known as a wind profiler, which measures the scattering of sound waves by atmospheric turbulence. SODAR systems are used to measure wind speed at various heights above the ground, and the thermodynamic structure of the lower layer of the atmosphere.
