The ROMEG Measuring Method

What is the ROMEG system?

ROMEG M 20 G is a laser-based measuring system for dynamic measurements on wind turbines.

Reflectorless laser-based distance measurement

With the ROMEG method, aerodynamically excited imbalances can be verified and mass-excited imbalances can be detected.

The measuring method is based on a reflectorless laser distance measurement. The laser measurement is performed while the wind turbine is in operation and can thus record the rotor geometry and the vibration behaviour of the tower under real operating conditions.

The system consists of two high-performance lasers which are aligned in such a way that the rotor blades are scanned at two profile sections as they pass the tower (tower passage).

Likewise, the axial tower vibrations are recorded between the tower-passes of the rotor blades.

The results are immediately available on site after data acquisition and analysis.

So why measure?

A well-balanced rotor leads to:

  • Higher yield
  • Longer service life of the wind turbine
  • Higher availability
  • Lower tower loads or less system load
  • Lower maintenance costs
  • Lower noise emission

Advantages of the ROMEG system

  • No yield losses due to downtimes.
  • The laser measurement is executed place on the running turbine under real operating conditions.
  • Fast measurement process: entire wind farms in a short time.
  • The results are quickly available on site and can be used immediately to optimise the rotor.
  • With the comparison of the vibration pattern before and after the correction, the success of the optimisation measure can be clearly proven.
