Detecting abnormal operating conditions and faulty control strategies

Very often operating loads occur, which are unknown in the load assumptions during the design phase and are therefore not taken into account. Experience shows that these are caused by different dynamic effects or faulty control and usually lead to damage and unexpected failures.

Because we have not only considered the classic aspects of condition monitoring in our KSM solution but have also optimized them with a deep understanding of drive technology and machine dynamics as well as system engineering, we can record irregular changes in system behavior. Every change in a system is associated with a change in the power distribution of the system and vibrations. We use this aspect to detect any anomalies in the operation.

The following images show analysis results of a KSM deployment on a wind turbine with a frequent pattern of damage to the main bearing. Through our solution and the intelligent algorithms, we were able to record relevant effects and trace them back to the origin. These effects can not be detected with the classical measuring and analysis methods.
