Efficient wind energy

The Condition Monitoring Systems from Rexroth provide operators a quick overview of the technical condition of their wind turbines.

Condition Monitoring Systems from Rexroth reduce cost of energy

Modern Condition Monitoring Systems (CMS) from Rexroth can permanently reduce the cost of energy (CoE) of wind turbines. The BLADEcontrol from Rexroth, which is certified by Germanischer Lloyd, provides continuous rotor blade monitoring and ice detection. The Advanced Condition Monitoring System ACoS incorporates even the entire drive train and other subsystems into the condition monitoring. The result: holistic monitoring with a continuous control desk link.

From certified rotor blade monitoring...

Because the Condition Monitoring System BLADEcontrol from Rexroth continuously measures, records, and analyzes the changes of the natural rotor blade frequency, a variety of causes for service calls can be detected early on from the control desk. This includes damage to the aerodynamic cover, the leading and tailing edges as well as the supporting structure of the rotor blades. On the basis of this decision, service teams can schedule measures promptly. The solution is available as an option on many new plants, but can also be retrofitted for existing wind turbines. Both the overall system and the BLADEcontrol ice detector, which is focused on the functionality of ice detection, are certified as the state of the art by Germanischer Lloyd in accordance with the "Guideline for the Certification of Condition Monitoring Systems for Wind Turbines, 2013 edition".

Experience shows that due to the preventive effect, investing in BLADEcontrol pays for itself within a few years of operation.

... to holistic Condition Monitoring

With the Advanced Condition Monitoring System ACoS Rexroth goes one step further. ACoS is the first solution that monitors both the rotor blades and the entire drive train – including rotor shaft bearing, gearbox, clutch, and generator bearing. For this purpose, Rexroth consolidated proven measurement and evaluation strategies in an open surveillance platform that can be expanded as needed thanks to standardized interfaces.

Examples of subsystems that can be seamlessly integrated into ACoS are modules for oil and tower monitoring or load monitoring for dynamic detection of the real loads in the drive train. For the control desk, ACoS uses all data and analyses collected to generate a simple yet detailed overall picture of the current state of the plant. On this basis, the control desk can optimize the operation and performance of the wind turbine.

“A good CMS solution is the best insurance against unplanned high maintenance and repair costs,” comments Dr. Dietmar Tilch, Managing Director for Technology at Bosch Rexroth Monitoring Systems GmbH. “Using the holistic condition monitoring, we can detect damage and impending failures in time and often even avoid them.”
