turbulence intensity
oct 20th, 2021 Turbulence Intensity: unlocking the mystery

Turbulence is one of the most elusive factors of wind production, impacting both on-shore and off-shore wind turbines.

Turbulence, expressed as Turbulence Intensity or the standard variation from an average wind speed , most often 10 minutes, is not only difficult to understand, but its impact and importance also vary with wind speed. At medium speeds though, productivity will decrease due to turbulence ; but this impact will diminish as speed increases towards cut-out.

The impact of Turbulence Intensity is most certainly inversely proportional to our efforts, and up to now, our ability to measure it.

mass and aerodynamic imbalance
oct 20th, 2021 Wobbling giants: why is rotor imbalance an issue?

The tip of a wind turbine blade can rotate as fast as 80 m/s. That is like driving at 300 km/h. When you are going that fast, you want stability. Rotor imbalance is a concern that increases with speed. With ever longer blades, this is a key issue. Whether the cause is aerodynamic or mass, any impact on its stability can be detrimental to both productivity and wind turbine life expectancy.

août 25th, 2021 Impact of Yaw on Productivity and Wind Turbine life extension

More than 60% of wind turbines show the presence of Static Yaw leading to performance loss and in half of these cases, the AEP loss is greater than 3%. Yet the importance of managing Static Yaw has not always been among the wind industry’s top priorities, especially with high subsidised wind energy prices.
