DNV GL has invited wind energy stakeholders to join a new Joint Industry Project (JIP) to explore the potential of using light detection and ranging (LIDAR) to measure wind speed turbulence intensity (TI) for various applications in the wind industry.
LIDAR is becoming the preferred technology for wind resource measurements, and various methods for deriving TI information from LIDAR measurements have been proposed in research settings, DNV GL said.
However, none of these methods has yet been verified and adopted within international standards, therefore, LIDAR measurements are not widely accepted by certification bodies, insurers or authorities.
By creating a Recommended Practice for LIDAR that is supported by players throughout the industry, the DNV GL-driven JIP aims to drive acceptance of LIDAR measurements and help reduce costs for turbine OEMs and wind project developers.
“Launching this Joint Industry Project is an important step in making LIDAR-measured Turbulence Intensity certifiable and accepted by different wind energy stakeholders,” said Kim Mørk, Executive Vice President Renewables Certification at DNV GL.
”As a certification body, it is our goal to support the wind industry in enabling cost-effective and reliable measurement of TI based on LIDAR data. The positive feedback we have already received from potential partners shows the strong desire within the industry for a new guideline.”
The JIP is intended for wind turbine and LIDAR manufacturers, wind farm developers, universities and research facilities, consultants and measurement institutes that are looking for guidelines to use LIDAR TI measurements for different applications. The call for partner’s phase is now open and organizations interested in joining should contact project managers Nikolai Hille and Frank Scheurich at DNV GL, Renewables Certification.
