Understanding the voice of your machine

Intelligent sound analysis for your hydropower plant

    Hydropower plants are already highly automated today and often located in remote areas, operating unmanned. As a result, problems might remain undetected and could cause severe damage to equipment.

    Hydropower plant operators rely on regular service cycles and monitoring systems to discover any anomalies that could lead to dangerous incidents. Without monitoring systems and advanced analytics, hydropower plant operators risk possibly dangerous conditions, especially with equipment that has no condition monitoring or is not continuously observed.

    With OnCare.Acoustic, Voith supports hydropower plant operators in discovering potentially dangerous incidents by detecting sound anomalies, classifying them into warnings and alarms, and allocating them to specific equipment. This allows information to be derived for smarter recommendations and decisions with regard to maintenance and operations.

    OnCare.Acoustic is based on Voith’s Industrial Internet of Things (IIoT) dataPARC cloud platform, and can be extended with more functionality by adding dataPARC cloud.Suite to the package.

      Modular packages for individual requirements

        The new modular OnCare.Acoustic offering supports hydropower plant operators in becoming aware of and discovering potentially dangerous incidents by detecting sound anomalies. The sound monitoring system contributes to ensuring the reliability, availability, and safety of hydropower plants. It is equipped with an acoustic sensor and the BlueBox for connecting data to the cloud. The offering includes different modular packages.

        Plant operators can be informed about suspicious, detected sounds that have already been preclassified in warnings and alarms. This helps customers to decide if they need to take action. By classifying the events and allocating them to specific equipment, plant operators get further insights into their hydropower plant and thus increase the probability of identifying possibly dangerous conditions, ahead of other alarms.

        Additionally, experts from the OnPerformance.Lab offer consulting services that include the analysis of inspection and maintenance reports in combination with operation and condition monitoring data. As a result, customers receive recommendations on how to improve their maintenance and operations.

          As our rivers often carry floating refuse, turbine clogging happens regularly. That’s the reason why we are testing also Voith’s OnCare.Acoustic in our pilot plant Rabenstein. The system already helps us with the detection of clogging in an early stage so we can flush the turbine. OnCare.Acoustic detects not only earlier but also more reliably than the human ear. In combination with the OnPerformance.Lab services, we can get advanced analyses and consultation. We are happy to have Voith as one of our partners in VERBUND’s digitalization program Hydropower 4.0.
