The advantages of permanent lidar for continuous wind measurement

What is a permanent lidar?

It is a solution wherein the lidar is permanently left on the wind farm for continuous operations. It extends further from Wind Resource Assessment and supports ongoing farm monitoring and operations.

What are the benefits of a permanent lidar at the turbine level?

WindCube as a permanent lidar, acts as a virtual met mast, measuring wind parameters remotely and eliminating the need for physical meteorological towers.

What are the benefits of a lidar at the wind farm level?

Permanent lidar at the wind farm level provides accurate, real-time wind measurements, improving monitoring and enabling performance optimization. It helps minimize operational and maintenance costs.

Is there any on-going research project about permanent lidar?

Our Research and Scientific team works extensively on identifying future developments and technological advancements. Thorough research is ongoing on how a permanent lidar can further be applied for wake steering and control, forecasting and grid management, and independent energy yield monitoring.

Which solution can support the permanent lidar application?

Wondering which product is the right fit for this application? Well, our WindCube lidar portfolio has a solution for virtually any scenario.

The WindCube vertical profiler, both onshore and offshore, provides continuous wind measurements and diagnoses any under-performance. It also provides independent wind measurements to claim compensation due to grid curtailment. Ground-based easy installation enables the lidar to cover the entire wind farm with a few devices cleverly located.

WindCube Scan ensures safe operations and maintenance services by detecting severe wind events like gusts, sudden change of wind direction etc., and improves wind modeling for a specific site.

WindCube Nacelle is the industry's first nacelle lidar to receive IEC classification for Power Performance Testing, to get the most of your wind turbine. It is proven to be effective in correcting yaw misalignment, detecting and correcting nacelle transfer function drift. Clever positioning of some turbines ultimately helps optimize wind farm production.

Why is lidar a good solution for permanent wind measurement on a wind farm? (all WindCube lidar USP)

Permanent lidar is a reliable solution in providing continuous, accurate, and real-time wind measurements, especially in severe weather conditions and no icing. WindCube also includes weather sensors PTH + Rain, making it a complete solution for all your requirements. Configurable measurement gates (height or distances) enable all types of applications.

Vaisala provides unsurpassed services and support anywhere in the world, including on-site maintenance to maximize uptime (1 day every 3 years), 3-years preventive maintenance with optional warranty extension, training, easy installation, and technical support. Various communication protocols enable access to real time data.

Why is lidar a good solution for permanent wind measurement on a wind turbine? (WindCube Nacelle USP)

When a lidar is placed on the nacelle of the wind turbine for permanent wind measurement, it constantly yaws with the turbine to provide continuous wind measurements including wind speed and direction, shear, veer, and turbulence intensity at hub height, leading to more accurate data. It helps the turbine adjust its blades to correct any yaw misalignments. Long range nacelle lidar enables measurement of wind ahead of the turbine.

Why is lidar a good solution for permanent wind measurement on a wind farm? (WindCube USP)

WindCube as a permanent lidar behaves as a virtual met mast. The lidar can measure up to even the highest turbine hub heights.
