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.

mai 31st, 2017 VALEMO orders 2 wind LiDAR from EPSILINE

Recently, VALEMO acquired two YawAdvisor™ wind LiDARs, developed and manufactured by the French company EPSILINE based in Toulouse, France.

The YawAdvisor™ is a nacelle-mounted wind LiDAR which measures the yaw misalignment of wind turbines. A yaw misalignment leads to production losses and increased stress loads on the wind turbine.

This investment is the result of a collaborative work between VALEMO and EPSILINE since two years. During this period, VALEMO and EPSILINE have realized two campaigns on two different technologies of wind turbine. The first campaign has been done on a SENVION MM92 wind turbine and the second one on a GE 2.5xl. Results of these campaigns have been fully satisfactory and lead to the decision to invest into two YawAdvisor™ in order to increase VALEMO’s capacity to provide this service to its customers.

avr 26th, 2017 EPSILINE and VENT D’EST extend Lease Agreement of YawAdvisor

EPSILINE and VENT D’EST have agreed to an extension of their lease agreement of the YawAdvisor, to include a 3rd campaign of data collection on a wind turbine owned by VENT D’EST, situated at the wind farm Voie Sacrée in the French department of the Meuse.

Previously EPSILINE has completed 2 campaigns of data collection for the account of VENT D’EST on Gamesa wind turbines G58 and G90, with satisfactory results.

EPSILINE’s nacelle-mounted wind LiDAR, the YawAdvisor™, provides a diagnostic report of the nacelle yaw alignment in comparison to the free oncoming wind in front of the turbine, allowing corrective measures for increased wind turbine performance and reduced stress loads.

VENT D’EST, a historical actor in the French wind industry, is a wind farm owner in the department of the Marne and Meuse, France.

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.
