UpWind will market Romo's iSpin wind measuring system that sits in front of a rotor to its US, Canada and Mexico customers.
Romo's iSpin is fitted on the nose of the rotor, and uses ultrasonic technology to measure wind speeds where it hits the turbine rotor.
The data collected allows project operators to ensure turbines are correctly aligned to get the best possible energy yield.
"Our experience shows that operators can increase the yield of their wind farm by two percent on average by correcting previously undiscovered yaw misalignments," said Jan Nikolaisen, co-CEO of Romo Wind.
Wind sensors are usually mounted in the turbine's nacelle, where their measurements are used to control start-up and shut-down, yawing, and, to some extent, optimisation of the rotor-blade pitch angle. Their measurements are also used to evaluate power curves and turbine performance.
But in upwind turbines, the nacelle is behind the rotor, and the rotor's turbulent effect on the wind driving the turbine compromises the accuracy of the sensors' measurements. Sensors in this position also fail to detect the presence of static yaw misalignments.
The iSpin technology developed by Romo Wind aims to fix this problem by measuring the wind with sensors that can be quickly and easily installed in the spinner, where the influences of the wind turbine rotor and spinner geometry on the flow are predictable and can be corrected for.
