From: A novel hybrid methodology to secure GOOSE messages against cyberattacks in smart grids

 

Description

Logical node class (IEC 61850-7-4)

XCBR

Circuit breakers—switches with short circuit breaking capability

XSWI

Circuit switches—switches without short circuit breaking capability

CSWI

Switch controller—control all switching conditions above process level

CILO

Interlocking function—enable a switching operation if interlocking conditions are met

Control parameter

XCBR/XSWI.Loc

Represents the status of an actual switch at the process and allows taking over the manual control authority

LLNO.MltLev

Enables for more than one originator to hold control authority at the same time

CSWI.Loc

Represents the control behavior of the logical node (bay level)

CSWI.LocSta

Represents the switching authority at the station level
