Communication networks and systems for power utility automation - Part 90-2: Using  61850 for communication between substations and control centres - Edition 1.0
 N TR 61850-90-2

Annotation

This part of IEC 61850, which is a technical report, provides a comprehensive overview of the different aspects that need to be considered while using IEC 61850 for information exchange between substations and control or maintenance centres or other system level applications. In particular, this technical report:

• defines use cases and communication requirements that require an information exchange between substations and control or maintenance centres

• describes the usage of the configuration language of IEC 61850-6

• gives guidelines for the selection of communication services and architectures compatible with IEC 61850

• describes the engineering workflow

• introduces the use of a Proxy/Gateway concept

• describes the links regarding the Specific Communication Service Mapping (SCSM)

This technical report does not define constraints or limitations for specific device implementations. There is no specific chapter for cyber security which is tackled when it is necessary. The model, for IEC TR 61850-90-2, provides security functions based upon the security threats and security functions found in IEC TS 62351-1 and IEC TS 62351-2. This technical report touches several security aspects with the following basic assumptions:

• Information authentication and integrity (e.g. the ability to provide tamper detection) is needed
