Software defined substations - a path towards cost effective and future-proof solutions
Summary Unlike renovating the entire secondary system of power substations, adding software defined functions save time and cost. Retrofitting the virtual Merging Unit running on a Substation Server offers an efficient future proof upgrade. Simply add a substation server, some sensors and the virtual Merging Unit application and get IEC61850 interoperability, advanced measurements, and a future proof platform for virtualized applications. The potential of moving towards a software defined substation:
  • Due to the energy transition TSOs and DSOs move to data driven system operations
  • Based on the average age of a substation, typically over 50% of legacy substations is not supporting the digitalization
  • Renovation of a secondary system for a substation takes 6 months 
  • The upgrade of substation automation functionality can be reduced by 50-80% by introducing software defined technology
