CPTT and IEC 61850

The IEC 61850 standard has been successively developed by [ IEC ] (International Electrotechnical Commission) in the last years. National standard commitees, like the German [ DIN ] (Deutsches Institut für Normung e.V.), have adopted the standard as national standard.

The application areas from IEC 61850 are communication networks and systems in stations. Not only does IEC 61850 define the message transmission between protection units, bay controllers, meters, etc. (station automation), but it also defines a supplier independent object model that describes process data.

The IEC 61850 standard parts define system and project management (IEC 61850-4), a configuration description language for station automation (-6), the object model (-7), the mappings for the communication between the devices (-8), as well as for the connection within the substation (-9) and conformance tests (-10).

IEC 61850 is positioned internationally including USA, Pacific, Europe and Asia.

IEC 61850 is used as a transmission protocol in the station automation.
The messages are generally exchanged through a network connection. The transmission between devices (horizontal communication) occurs preferably through GOOSE, and the transmission to the control system (vertical communication) through MMS.

COMPROTware:Testtool offers in this protocol:

• IEC 61850-8-1 from May 2004 is implemented.
• Network Monitoring.
• Display of mappings MMS (Manufacturing Message Specification) and GOOSE (Generic Object Oriented Substation Event).
• Different application oriented view formats for message traffic.
