Vaisala’s WindCube Nacelle Turbulence Intensity algorithm improvements demonstrate high measurement accuracy and data coverage for wind energy applications

Vaisala, a global leader in weather, environmental, and industrial measurements, today announced the publication of a comprehensive report demonstrating how its WindCube Nacelle lidar  provides accurate Turbulence Intensity (TI) measurements suitable for use across industrial applications. 

“The culmination of extensive lidar research and development efforts, our pioneering nacelle-mounted lidar solution is designed to provide reliable wind data at multiple distances in front of a wind turbine,” said Frédéric Delbos, Head of Science – Renewable Energy, at Vaisala. “From Power Performance Testing (PPT) to wind turbine load estimation and turbine optimized control of loads and production, Turbulence Intensity plays a critical role in various wind energy applications.  So the accurate TI measurements WindCube Nacelle unlocks help advance nacelle-mounted lidar usage in the wind industry.” 

Building on Vaisala’s deep renewable energy measurement expertise, WindCube Nacelle provides a transformative approach to TI measurements at low costs. In a recent white paper, Turbulence Intensity Measurements with WindCube Nacelle, Vaisala showcased the remarkable capabilities of its nacelle-mounted lidar system. Summarizing the results of three field campaigns, the white paper demonstrates the accurate TI measurement achieved by WindCube Nacelle and serves as a solid foundation for further investigation. 

The high measurement accuracy and data coverage observed in these results affirm that WindCube Nacelle is primed for wind energy industrial applications. Additional white paper findings contribute to improving TI measurement techniques and pave the way for further exploration of the temporal-spatial structure of air turbulence in the low atmospheric boundary layer. 

Industry giant General Electric Renewable Energy recently acknowledged the significance of TI measurements, accepting WindCube Nacelle lidar for Power Performance Testing. This acceptance further underscores the industrywide importance of innovative solutions like WindCube Nacelle. 

Wind energy players, including Vaisala, are committed to continued TI innovations in order to improve accuracy of critical wind measurement campaigns.
