Sodar, Sonic Detection and Ranging, is acoustic equipment that is easily deployed at existing or proposed wind project sites to accurately measure the boundary layer’s wind profile and turbulence structure at heights above conventional meteorological towers.
AWS Truepower says it has Sodar units available for lease with support from its team of professional meteorologists and engineers. Client units are also welcomed and supported. Sodar, or Sonic Detection and Ranging, is acoustic equipment that is easily deployed at existing or proposed wind project sites to accurately measure the boundary layer’s wind profile and turbulence structure at heights above conventional meteorological towers. Acting as a virtual tower, Soday reliably measures the wind profile up to heights of 150m. This information provides definitive information about the winds at the hub heights of today’s large wind turbines. Measurements at hub height, and also across the entire rotor plane, give the most accurate predictions of wind plant output.
The company says Sodar equipment can:
• Provide high-resolution wind speed and direction data throughout the rotor plane
• Directly measure the wind flow within the turbine rotor layer
• Significantly reduce uncertainty related to wind speed and energy production
• Quantify individual horizontal and vertical wind flow components
• Measure turbulence levels throughout the rotor plane
• Identify flow discontinuities that fixed met towers miss
• Measure wind speed in a volume of air, not just at one point
• Confirm or revise the wind shear aloft defined by on-site fixed towers
• Reduce the number of conventional met towers needed to qualify a site.
