Higher Yield with Reduced Loads
Identify and fix aerodynamic rotor imbalances.
Blade angle differences are the number one cause of aerodynamically excited imbalances. From an angle difference of 0.5° the tower shows a swinging behaviour characteristic of an unbalanced oscillation. The tower vibration is a good indicator for the level of imbalance.
The ROMEG method was developed by windcomp GmbH and is based on a reflector less laser distance measurement on the WTG in operation. With ROMEG measurement we log the blade profiles, the tower movements and the blade-deflection.
In the subsequent data analysis we evaluate the behaviour of tower and rotor.
The results are immediately available on site after data recording and analysis.
