Condition monitoring solution proves successful at Icelandic dam11 July 2022

Voith Hydro's OnCare.Diagnostic Professional has proven itself at Landsvirkjun's Budarhals power station in the south of Iceland, providing early detection of anomalies and thereby enabling optimal plant uptime.

In the course of Budarhals’ annual inspection in April 2022, the reports of OnCare.Diagnostic Professional and the input from OnPerformance.Lab experts in Heidenheim were considered. During the startup of the unit right after the inspection, a malfunction was detected in the automation of a machine unit, so that the unit could only be controlled manually in emergency mode. Within less than 24 hours, the root cause was identified by the OnPerformance.Lab and Voith Hydro Automation team, together with Landsvirkjun, and could be solved within only a few days. The immediate support from Voith Hydro helped the customer bring the unit back to optimal condition and keep downtimes to a minimum. Landsvirkjun expressed its satisfaction with the early extension of the contract for another two years through June 2024.

With its digital health assessments, Voith Hydro provides reports and recommendations for condition-based maintenance activities of the power station, based on an intelligent analysis of the existing plant data. Since its introduction to the market two years ago, Voith Hydro’s Diagnostic Services offering has been continuously developed and revised.

In addition to general enhancements of the information provided by the digital health assessments, the malfunction values that indicate anomalies in the power plant have been expanded. This has led to an increase in efficiency in the provision of analysis results, so that more than 60 so-called Health Status Indicators are evaluated. In the future, diagnostic services will be further expanded to include automatic, digital condition assessments of plants.

In parallel to the product optimization of the existing solution, Voith Hydro is also working on expanding its portfolio in the field of diagnostic services and is now creating the new OnCare.Diagnostic product family.

Under this umbrella, the optimised version of the digital health assessments will become OnCare.Diagnostic Professional. It includes the already established reports that are supplemented by professional consultancy through targeted support from Voith Hydro experts – in the OnPerformance.Lab in Heidenheim, Germany. In this way, the analysis results and detected anomalies are directly linked to the associated risks and professional recommendations in order to enable precise planning of maintenance work and prevent unplanned shutdowns.

Another solution, which is still under development, is to be added to the product family in the course of the year. The OnCare.Diagnostic Base solution will enable automatic malfunction diagnostics and provide recommendations for maintenance activities as a software-as-a-service. These are designed to be uncomplicated and time-saving.
