There is a large need for automatic asset management in order for the grid owners to be able to streamline preventive maintenance. The power quality measurement and new pro-active trend analysis can possibly detect incipient faults at a very early stage.
The theory for this work package is that new development including pattern recognition techniques can be used for pro-active trend analysis to minimize the total interruption time for the electrical grid. In this work package, solutions will be developed and tested to verify this assumption.
The work package will include two main areas below:
• PQ System Pro-Active Trend Analysis – using historical power quality data.
• PQ System Pro-Active Fault Analysis – using historical disturbance (waveform) data.
Release of first PRO-ACT module
Metrum has developed and released the first client module “METRUM PROACT” that was recently presented at the ELFACK-exhibition in Gothenburg 9-12 May. The PRO-ACT module is web-based and show the pro-active trend analysis data based on pattern recognition technique and that has been implemented during the ERA EPR project WP2.
