DNV has published a new Recommended Practice document that provides the wind power industry with in-depth information regarding use of remote wind sensing equipment used to characterizing wind resources. Document (DNV-RP-J101) addresses the use of Sonic Detection And Ranging (SODAR) and Light Detection And Ranging (LIDAR) equipment. These have been developed by DNV’s specialists in…
Program gets community wind access to better wind sensors
A manufacturer of wind measurement equipment has announced a program to fuel the growth of community-scale wind power projects. The Community Wind Information Service uses leading-edge wind measurement technology from Second Wind Inc, to provide comprehensive wind resource analyses to individuals and groups considering wind turbines. The service will let community wind developers decide quickly…
Sodar measures wind higher than tower and with lower uncertainty
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…
Leasing comes to large wind sensors
A wide range of wind-energy companies can measure hub-height wind speeds by using reliable and dependable remote sensing systems in wind resource assessments. Second Wind has announced a flexible leasing program for its Triton Sonic Wind Profiler. The leasing program, operated through recently-established Second Wind Financial Services, is the first manufacturer-supported third-party leasing program for…
Sound intelligence in the search for wind power
Reprint Info >> The wind industry’s need for wind measurement has grown beyond the 60-m reach of standard meteorological (“met”) masts. To reduce uncertainty for wind projects that can cost anywhere from $100 million to $1 billion, the industry needs data from the entire rotor sweep that can’t be gleaned from 60, 80, or even…
Its official: NREL says sodar data as good as from met towers
Sodar or sonic detection and ranging, is a relatively recent tool for measuring wind speed and direction up to 200-m up. The task was usually relegated to meteorological tower that had to be built and often reached only 80-m up. Portable sodar units simplify the task. Recently, as part of continuing scientific research to understand…
