    How it works

      An increasing number of devices create data to enable response at an early stage. However, there is more often a lack in in-depth knowledge when it comes to analyzing data. That’s why Voith supports customers with a team of experts . Learn more about the functional principle behind the OnPerformance.Lab

      The web interface OnPerformance.Lab Interact is where all information comes together. To be able to ensure a clean and fast data exchange a few steps are required.

      1. On-site assessment of all condition monitoring systems incl. sensors by the OnPerformance.Lab team.
      2. Hydro operator sets analysis priority and uploads data on the platform OnPerformance.Lab Interact.
      3. OnPerformance.Lab assesses machine health.
      4. Hydro operator reviews the recommendations.
      5. Reports and recommendations are continuously updated based on clients needs.

        Our Service

        Remote Troubleshooting of excessive relative bearing vibration of the generator

        What was the challenge?
        The customer recorded high levels of relative vibrations at the upper guide bearing of the generator which several times caused alarm warnings. The vibrations were around border C/D of ISO 7919-5. Without a planned outage the local staff wasn’t able to identify the root cause. Voith was asked to access remotely and perform a troubleshooting.

        What did Voith do?
        Voith’s service team collected and analyzed data using the remote access to the power plant monitoring system. The dataset was recorded while the unit was running at different modes of operation, from steady state to maximum load. With the data the team made a complete vibration analysis. The high vibration root cause was identified and quantified as a combination of the upper generator shaft misalignment (60%) and the generator rotor unbalance (40%).

        What was the value to the customer?
        Voith reduced 35% of the shaft vibration through rotor balancing and eliminated the alarm warnings in all operation condition. A possible improvement on the vibration reduction through a shaft alignment can be adequately planed. This measure avoided an outage of a 150 MW unit for at least 3 weeks for unplanned corrections on the shaft alignment. This is estimated to have avoided approximately €226,800 in costs (based on average production loss).

        Health check of the hydraulic machine of pump turbine unit

        What was the challenge?
        In winter, the customer observed high vibrations on his machine and subjectively assigned this to a problem with the guide bearings. As part of a service contract, Voith was asked to collect archived data via remote access and to analyze the observed vibrations.

        What did Voith do?
        The Voith service team was able to collect and analyze the relevant data via the condition monitoring system. The analysis showed that the measured absolute vibrations on the stems of two guide vanes increased significantly within a few weeks. This indicated that the observed vibrations were caused by a high level of wear of the two guide vane bearings.

        What was the value to the customer?
        The analysis provides the necessary transparency for foresighted action with regard to the two guide vane bearings. Based on this, they were replaced during two planned machine downtimes aligned with the observed vibration levels. By using the knowledge of our OnPerformance.Lab experts, the issue with the pump turbine unit could be solved faster. This increased the availability and reduced the effort on site.

        Remote Troubleshooting of excessive vibrations on the pelton runner

        What was the challenge?
        The machine suffered some trips (protection system stops the unit automatically) without that the local staff could identify the root cause.

        What did Voith do?
        Voith's service team collected and analyzed data representing the vibration levels and operative parameters an engineer remotely was able to understand how the nozzles have been applied by the customer during operation. Through a data analysis it was understood that the way the nozzles are operating was inefficient. This was the root cause of the vibration. We helped the customer define a new pattern for operating the nozzles.

        What was the value to the customer?
        By adjusting the nozzle installation damages to the machines could be avoided and the expected lifetime of the shaft line components increased. This is estimated to have avoided approximately €52,560 (4% availability ) in costs (based on European average production loss.)
