The YawAdvisor™ is a turbine mounted Laser Wind sensor (Wind LIDAR) that enables accurate wind direction measurements immediately in front of the wind turbines, avoiding disruptive wind turbulence in the traditional measurement zone behind the blades.
Specifically designed to provide the wind farm owners, operators and maintenance companies a fast, reliable, flexible and economic tool to assess the proper alignment of wind turbines.

YawAdvisor™ provides valuable information regarding the angle between the actual wind flow and the nacelle centerline, up to 10 m ahead of the sensor.
Based on the information provided by the YawAdvisor™ during the measurement campaign, the wind farm owner, operator & maintenance company can decide on further actions needed to optimize the alignment.

Technology


Our innovation is the culmination of 15 years of research and expertise in optoelectronics conducted within EPSILINE in partnership with certified laboratories.

Understanding the behaviour of laser sources, combined with an intelligent electronic detection is at the heart of the systems we develop. Our research team consists of specialists in electronics, embedded systems, micro-sensors, laser optics, velocimetry and wind data analysis.

Measurements of wind direction with laser are based on the well-known principle of the Doppler Effect: Laser beams are reflected by particles (dust, pollen, etc) carried by the wind, a fraction is collected and then processed to derive the radial velocity of the particle. This information is used to calculate the direction of the wind accurately.

sept 22nd, 2016 Come and see us at WindEnergy Hamburg 2016

Concerned with Yaw Misalignment and lost revenues. Come and see us at WindEnergy Hamburg 2016 and learn about our YawAdvisor®. The YawAdvisor® is a nacelle-mounted laser wind sensor specifically designed to detect yaw misalignment of wind turbines. This robust, highly reliable and cost effective solution has been specifically conceived to be used as a diagnostic tool, that is easy to install and uninstall and that can be rotated from turbine to turbine. Please contact us to arrange a meeting or visit our stand (Hall A4, stand 158), and it will be a pleasure to welcome you.

sept 16th, 2016 Another Stride for EPSILINE

With the summer months coming to an end and the beginning of the wind season, EPSILINE has successfully installed a YawAdvisor™ wind Lidar for VENT D’EST, a wind farm owner, for the evaluation of the system operations and benefits at a commercially operated wind farm in the North of France.

 

On a hot summer’s day in mid-August, with temperatures soaring to above 40° in the nacelle, EPSILINE, lifted, installed, aligned and switched on the device to begin a campaign of measures to determine the angle of the oncoming wind in front of the turbine and compare it with the angle of the nacelle. The installation was completed successfully within 4 hours, and accordingly minimized the down time of the wind turbine.

 

The YawAdvisor is the first of Epsiline’s “next generation” turbine yaw diagnostic system for utility-scale wind turbines. From its position on top of the nacelle, the YawAdvisor measures wind direction in front of the turbine, providing a yaw offset report to wind farm owners, operators and maintenance companies and thus giving insight necessary to optimally understand and control a wind turbine’s yaw performance for the purposes of increasing energy output and reducing damaging stress loads.

sept 9th, 2016 EPSILINE leads successful end to Wind measurement campaign

EPSILINE has successfully concluded a wind measurement campaign in partnership with the company Valemo.  EPSILINE’s YawAdvisor™, is a wind LIDAR dedicated to yaw misalignment detection on wind turbines. The YawAdvisor™ gathered data on a commercially operated wind farm in the region of Loire-Atlantic, France.

 

The diagnostic report has indicated a significant misalignment of the Yaw and recommends an investigation by the manufacturer and owner, to determine the cause of the misalignment. The corrective measures could include a recalibration of the traditional wind vane, or a correction of the NTF to take into account the Yaw error.

 

Once the corrective measures have been implemented, a second campaign is recommended to validate the correction. It would also provide an ideal comparison of the power curves before and after the correction of Yaw.
