Accurate wind measurement can be achieved utilising the full power of nacelle-based LiDAR technology for both onshore and offshore.
Measuring the wind affecting a turbine has been a continuing problem in the wind energy industry. Accurate measurement of the power curve, average yaw misalignment, turbulence intensity profile and nacelle transfer function can be achieved through in-depth expertise harnessing the full power of nacelle-based LiDAR technology (Light Detection and Ranging).
Ventus Group is ready with a fleet of LiDAR instruments, along with in-depth expertise for measuring, analysing and optimising wind turbine performance. Our multiple types of LiDARs can obtain accurate measurements for all turbine makes and models both onshore and offshore.
Fleet of LiDARs
Review and planning of feasibility on the wind turbine, whereas installation is possible on any kind of nacelle for all turbines and models. With a fleet of LiDARs we provide a fast and flexible evaluation of the wind turbine in accordance with the IEC61400-12-1 standards.
Our highly experienced team of technicians temporarily mount the nacelle based LiDAR on top of the nacelle along with a number of calibrated instruments as well as a data collection and communication unit inside the nacelle.
The LiDAR measuring project can last between two and twenty weeks depending of the client’s wishes for gathering relevant wind data.
