Windfit Yaw Performance Analyzer
- Do you see unexplained scatterings on your power curves?
- Do you experience excessive wear on your yaw drive?
- It is time to monitor the yaw system of your wind turbines.
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.
How can Windfit help you?
Windfit monitors key metrics about the yaw system and identifies irregularities such as:
Low yaw speed: A slow yaw is an immediate loss in production. This can be the symptom of an abnormal yaw drive wear and a precursor of an immobilising failure.
Excessive yaw speed: This rare condition can be linked to uncontrolled yaw drive slips, rendering the turbine unable to stay upwind.
Rare and large yaw movements: If implemented in an area of mildly varying wind directions, a lazy yaw system leaves the turbine misaligned for too long before properly facing the wind. These misalignments lose power and cause asymmetric loads on the turbine structure.
Small and frequent yaw movements: On the other hand, an hyperactive yaw system causes excessive mechanical wear and maintenance burden without any perceptible performance gain.

Windfit Technology
The measurement system is concentrated in a single module, quickly and easily installed in less than an hour and completely independent from the SCADA.
The Windfit module integrates various sensors such as compasses and gyroscopes. It autonomously selects optimal conditions for data acquisition, processing, and transmission to the web platform.
The Yaw Performance Analyzer detects and measures each yaw movement, statistically aggregates their parameters and delivers simple diagnostics.
The Windfit web platform ensures the quality, processing and secure storage of information.
