Measuring method for determining imbalances


 

 

our service offer is mobile measurements. with the ROMEG and AIDA measuring systems developed by us, aerodynamic and mass-excited imbalances can be detected with high precision and in a simply way during normal operation of the plant.

 

Characteristics:

 

  • No downtimes
  • Measurements under real operating conditions

 

Results are available on site and can be used immediately for corrections.

 

 

 

Laser measurements with ROMEG

We use ROMEG laser measurement system to detect imbalances in the rotor via dynamic geometry measurements.

 

Measured variables are:

  • Profil contours
  • Tower vibrations
  • speed changes

The laser measurement method now represents the state of the art. More than 10.000 wind turbines have been measured worldwide using this method.

The ROMEG method is characterized by high reliability and records not only the blade profiles but also the tower head vibrations and speed changes to determine mass imbalances.

Acoustic measurements with AIDA

The acoustic method AIDA is especially suitable for measurement of offshore wind turbines.

 

With AIDA the sound emission of the rotor are recorded and analyzed.

 

In the evaluation a frequency analysis of the time period is performed.
