Pitch angle monitoring

Avoid aerodynamic imbalances and their negative effects efficiently by continuously measuring relative pitch angle.

Insights

Challenges

Reduced performance

Even minor, permanent pitch angle deviations can severely impact your assets, shortening the service life of key components. Misalignments also reduce energy output, increase maintenance costs, and compromise safety. Close monitoring is essential to avoid these negative effects and ensure optimal performance and longevity of your equipment.

Challenges

Performance losses

Undetected misalignments could cause performance loss and reduce the life span of the wind turbine.

Challenges

Increased fatigue

Blade angle misalignments could result in damage like broken blades, damaged bearings, cracks and increased fatigue, resulting in expensive repair costs.

Challenges

Long repair downtimes

Downtimes lead to considerable yield losses.

Challenges

Increased Costs (OPEX)

Repair and personnel costs for operators are heavily increased if misalignments are not detected at an early stage.

Challenges

Reduced service life

Operation with misaligned blades leads to reduced service life of wind turbines.

Challenges

Misdiagnosis

Misdiagnosis of imbalances can lead to further invest in resources.

Features

How our :ALIGN system helps you

Aerodynamic imbalances caused by pitch angle deviations between rotor blades are critical aspects that often receive too little attention. Our :ALIGN system enables operators to react early to changes before they develop into major misalignments.

Fully automated –

More time for other priorities

Our system performs continuous measurements and automatically alerts, freeing you up to focus on other important projects and processes.

Easy data correlation

Our system allows for easy data export, simplifying the process of comparing correlating data with your system’s performance metrics.

<p>Check icon</p>

Increase performance

:ALIGN uses our ON-BLADE technology to monitor pitch misalignments by measuring blade accelerations in three directions simultaneously. This data is used to determine rotor speed and blade alignment, optimizing wind turbine performance and reducing fatigue (if detected error is corrected).

No rope access required

There are different mounting options for installing the :ALIGN system. No rope access is required for any of them.
