Since 2020, Valemo has its own CMS analysis service to offer a remote monitoring service of the vibration behavior of wind turbines. Our experts work in close collaboration with VALEMO’s control and operation departments to ensure optimal follow-up of diagnostics and corrective actions.
Principle
The measurement of vibrations is carried out by positioning about ten accelerometers on the main components of the kinematic chain (rotor, gearbox, generator):
Example of instrumentation configuration :
Each turbine is equipped with an acquisition system that collects and transmits the measured data in real time to our dedicated server:
Valemo is equipped with the most powerful software for signal analysis and detection of vibration alarms.
Types of mechanical defects
From detection to corrective action
Example: HSS bearing defect on multiplier
The Valemo service offer
- On-line vibration analysis and monitoring of most turbine models on the market. We adapt to the CMS equipment installed on site, by proposing according to the cases:
- A monitoring in parallel with that performed by the maintainer to independently assess the health of the parks in operation. In this case, a gateway is set up to VALEMO servers and analysis tools.
- Installation of dedicated CMS systems by VALEMO for the oldest parks that are not equipped.
- Sending of anomaly reports including a diagnosis and recommendations for corrective actions or additional analyses (oils, endoscopy…)
- Requests for field feedback to the maintenance manager, follow-up and follow-up of corrective or preventive actions.
Our know-how is based on 10 years of experience in the O&M activities of wind farms.
Benefits of independent CMS monitoring
- Objective analysis of SMD data for the owner and/or operator to assess the risk of failure and optimize production before programming a corrective action.
- All the information related to the operation (turbine stoppages, maintenance operations, production) are taken into account by our experts to diagnose failures and propose preventive or curative actions.
- The data supervised by VALEMO’s data engineering department and the vibration indicators can be analyzed jointly to determine the cause of recurrent failures on a fleet of turbines in operation. Example: analysis of bearing temperatures.
- Finally, the vibration data are repatriated and hosted in the VALEMO data lake. The customer has the guarantee that the data history remains accessible for further analysis if needed.
