Windfit Performance Index

  • Quickly identify underperforming wind turbines.
  • Prove the effectiveness of your maintenance operations.
  • Detect long term negative performance trends.

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.

How can Windfit help you?

Optimized for sensitivity, Windfit Performance Index measures the performance of the turbine itself and detects performance issues as soon as possible while ignoring seasonal and random external variations.

At the same wind speed, a dense cold wind stores much more energy than a light hot one. Measuring the performance of a wind turbine can be very misleading if you only consider the wind speed. Thanks to its environmental sensors, Windfit is able to compensate for the variations in air density.

Regarding variations in wind turbulence, Windfit also filters wake sectors using its autocalibrating compass. This further stabilizes the Performance Index and allows for reliable long term trend comparison.

In addition to the Performance Index, Windfit generates a power curve from real measurements and compares it against the manufacturer's reference.

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 a compass, a thermometer and a barometer. It autonomously selects optimal conditions for data acquisition, processing, and transmission to the web platform.

The Windfit web platform ensures the quality, processing and secure storage of information.
