SCADA Integration of Distributed Substations via IEC61850


SCADA Integration of Distributed Substations via IEC61850



A major international airport in Germany needed to upgrade its privately managed power grid. The grid has energy requirements equivalent to a city of 150,000 people, and is managed from a central location. 


Customer challenges


  • 6 substations distributed over 25 square kilometers

  • Over 100 types of equipment with different protocols

  • Availability and security both of critical importance

  • Limited experience and knowledge of IEC 61850


The solution: HMS & EcoStruxure


The customer decided to use Ixxat SG-gateways with IEC 61850 connectivity from HMS Networks to establish connections among the equipment, as well as with the central monitoring room. The solution included:


  • MiCOM Protection Relays in Modbus-RTU

   Third-party sensors, actuators, or Genset controllers

   Ixxat SG-gateways by HMS Networks 

  • EcoStruxure™ Power Operation (previously Power SCADA Operation)


Customer benefits


   Fast implementation, thanks to ease of use of Ixxat SG-gateways 

  Simple system with 1 SCADA and 1 gateway type to connect multi-vendor equipment running different protocols

  High security of IEC 61850 for critical application
