Load monitoring
Wind turbines are exposed to dynamic and complex loads that can affect their performance, reliability, and lifespan. Load monitoring provides measuring and analysis of these loads and use the insights to:
INCREASE ENERGY PRODUCTION
using input from sensors to perform individual pitch control to maximize output while keeping loads under control.
REDUCE OPERATIONAL COSTS
by extending the lifetime of components and planning maintenance activities based on the actual load history.
ENHANCE SAFETY
by avoiding overloading and documenting the structural integrity and fatigue life of the blades.
OPTIMIZE BLADE DESIGN AND MATERIAL COSTS
for new turbine models.
UNLEASH THE POTENTIAL
of your existing turbines models. The more insights you gain the more possibilities of using the same turbine type in a wider range of weather conditions and geographical locations.
Benefits of SENACT® Load
We offer a comprehensive load monitoring system that uses fiber optics technology to measure the loads on each individual blade.
With SENACT® Load, you get:
- Reliable load insights thanks to the high measurement accuracy it allows you to operate your wind turbines safely and to their fullest potential by providing both flapwise and edgewise bending moments.
- Fast installation and low maintenance costs due to the use of ruggedized components, less -wiring and cabling and independent calibration.
- Compatible with any type and size of wind turbine.
ABMC – Load calibration made simple
Autonomous Bending Moment Calibration (ABMC) is a software module that enables accurate and efficient calibration of blade load sensors.
Blade load monitoring requires calibration, which is the process of converting the measured strain into bending moments. Calibration typically requires onsite personnel, and it can take several hours or days per turbine to complete. It is therefore a time-consuming and costly process. Calibration is also sensitive to weather conditions (e.g., wind speed and temperature) and it needs to be repeated periodically, as the blade properties change over time due to fatigue.
ABMC solves these challenges by automating and optimizing the calibration process. It can be activated remotely or can be automated, and it can be configured for different types of calibration depending on the wind speed and the quality target.
ABMC uses a model-based approach to calibrate the sensors repeatedly. It always compares the new calibration with the previous one and can be activated if it is better or within a certain deviation threshold. This leads to improved calibration accuracy and therefore improved load data.

- Heavily reduced calibration time minimizes the loss of AEP and downtime.
- Reduced resources as calibration takes place independently without the need for onsite personnel, data analysts, or support functions, lowering the calibration costs.
- Improved accuracy thanks to multiple calibration iterations at low wind speeds to reach your desired quality target.
- Improved reliability and safety through constant sensor and system health check that can detect and report sensor or system issues.
- Improved turbine performance as ABMC provides accurate and reliable blade load data to maximize the AEP and minimize fatigue and risk of -damage.
