Substation Automation Concept

Substation Automation Concept

Working Principle Of Substation Automation concept

  • However the information from these relays is limited to data from signal contacts included in the relays.
  • Separate transducer for voltage and currents can however be added to conventional relays.
  • Signals from the conventional relays can be hardwired to the numerical ones. By this arrangement both existing relays and new numerical relays can communicate via a com-mon fibre-optic bus. This makes the concept suitable for partial retrofit as well as com-pletely new installations.
  • The ABB Substation Automation concept has five corner stones.
  • Protection
  • Communication
  • Control
  • Monitoring
  • Tools
  • One of the main advantages of ABB Substa-tion Automation is that it may include build-ing blocks from various product ranges and generations. High performance and total quality are the major requirements for each building block.
