Dynamic Laser Measurements of wind power plants

 

 

Our service offering includes mobile measurement so wind power plants. Both aerodynamic and mass-related imbalances can be detected using the laser system we have developed.

 

  • The measurements are performed while the plant is running.

 

Advantages of our method:

  • No yield loss due to downtimes
  • Measurements under real conditions

 

The measurement results are available on site and can be used immediately for corrective actions.

 

 

An unobstructed view of the turbine of approx. 100m in the wind direction is required for the measurements.

 

The following measured parameters are determined and analysed to evaluate the plant behaviour:

  • Profile contours of the blades at two cross-sections
  • Speed changes
  • Movements of the tower at two heights
  • Tower clearance at tip area

 

Example measurement results before and after imbalance correction:

 

                      Initial measurement

Blade profiles/angles outside of tolerance

 

Tower movements with aerodynamic imbalance

 

Tower movements with mass-related imbalance

FFT-analysis

                         corrected

Blade profiles/angles within tolerance

 

Tower movements without aerodynamic imbalance

 

Tower movements without mass-related imbalance
