Grid Requirement tackled
- Grid reliability is crucial for grid operators, especially during the energy transition.
The dominant origin for outages in MV grid are cable damage (excavation) and joint failures.
Approach & solution
- Smart Cable Guard (SCG) is an online sensor system designed to prevent power failures by precisely localizing partial discharges in joints and cables that precede a failure. The system can even detect faults that occur outside the monitored section.
- The personnel needs to be trained in interpreting the events that come from the accompanying AI powered detection software.
- The data analysis of the solution needs to be monitored for its events. This role can be located within Grid Operations but is better suited in a dedicated System Operations business unit.
- It is both investment types – Capex for the sensors and installation, Opex for the operation of IT infrastructure and software.
Benefits
What is the technology’s impact on below areas?
- See above
- Customers, fast recovery time when faults occur and prevented outages
- SAIDI of the total MV-grid has been reduced by about 2 minutes per customer (~15% of total); more than 250 outages have been prevented using SCG in the last five years; SCG is integrated into the outage management system and allows immediate fault localization, reducing recovery time by 20%.
