Common logical node information

Logical nodeLogical nodeinformation

information independent from the dedicated functionrepresented by the LN, e.g., mode, health, name plate,...

information representing either the status of the processor of the function allocated to the LN, e.g., switch type,switch operating capability, ...

Status information

information needed for the function of a logical node,e.g., first, second, and third reclose time, close pulsetime, and reclaim time of an autoreclosing function.

Settings

are analogue data measured from the process orcalculated in the functions like currents, voltages, power,etc., e.g., total active power, total reactive power,frequency, net real energy since last reset, ...

Measured values

are data, which are changed by commands likeswitchgear state (ON/OFF), tap changer position orresetable counters, e.g., position, block opening, ...

ServerDirectory

Applicationassociation

Provision of how two or more devices can be con-nected. Provides different views to a device: restrictedaccess to the server's information and functions.

AssociateAbortRelease

Logical device Represents a group of functions; each function is de-fined as a logical node.

LogicalDeviceDirectoryGetAllDataValues

Logical node Represents a specific function of the substation sys-tem, e.g., overvoltage protection.

LogicalNodeDirectory

Data Provides a means to specify typed information, e.g.,position of a switch with quality information, and time-stamp.

GetDataValuesSetDataValuesGetDataDefinitionGetDataDirectory

Service model Description Services

Reporting and log-ging

Describes the conditions for generating reportsand logs based on parameters set by the client.Reports may be triggered by changes of processdata values (e.g., state change or deadband) orby quality changes. Logs can be queried for laterretrieval.

Reports may be send immediately or deferred(buffered). Reports provide change-of-state andsequence-of-events information exchange.

Conformance testing


IEC 61850SCC

Scope

This part of IEC 61850 specifies methods for

conformance testing of devices

of substation automation systems.

In addition it gives guidelines for setting up testenvironments and specifies levels ofinteroperability. Thus it enables the

investigation of conformance claims and toestablish their validity.
