Highly reactive performance assessment without relying on SCADA.

Validating the integrity of the foundations of each wind turbine is a regular maintenance requirement.

Wind turbines yaw misalignment is a simple issue which happens much more often than it should: a fairly common misalignment of 8° translates to 2% AEP loss. While the problem has been known for a long time, existing solutions often fail in terms of simplicity, practicality and cost effectiveness. Windfit quickly and accurately detects yaw misalignments, without relying on SCADA measurements or expensive equipment.

The power curve is the tool of choice to monitor and readily detect a wide range of issues affecting the wind turbine production. However, power curves can be hard to interpret when the wind availability and environmental conditions change every month. Windfit Performance Index combines production and wind speed data from SCADA with the high frequency compass and environmental parameters captured by the Windfit sensor to produce a stabilized performance index.

Between 30% and 50% of the wind turbines are concerned by rotor imbalance problems. Windfit provides a continuous and online diagnosis of the rotor balance status of each equipped wind turbine without any field intervention or SCADA analysis.

The wind vanes, the yaw controller and the yaw drive are in charge of aligning the turbine with the wind. By minimising the angle between the wind and the turbine, the power output is maximized and non-symmetrical loads are avoided. Even when a wind turbine is, on average, perfectly aligned, a turbine lacking reactivity spends too much time lagging behind the dynamics of a real wind and ends up always misaligned.
