GOOSE Analyzer Operator's Manual
GOOSE Analyzer Engine
Using GOOSE Analyzer Engine
GOOSE Analyzer Engine provides means to verify and validate GOOSE signals against
GOOSE configurations in the substation configuration description (SCD). The engine
continuously analyzes the decoded GOOSE packets and monitors the availability, reliab-
ility, and status transitions of GOOSE. Outputs from the engine are updated to the user
interface in various ways.
Three types of analyzers are implemented in the analyzer engine:
•
Subnetwork analyzer group
•
IED analyzer group
•
GOOSE control block analyzer group
Subnetwork analyzers
Subnetwork analyzer group
This group is designed to analyze subnetwork wide GOOSE with comparison to the
corresponding configurations in the SCD.
The following analyzers belong to this group:
•
Intrusion analyzer
•
Statistic analyzer
Intrusion analyzer
GOOSE intrusion is a GOOSE message whose configuration is not listed in the system
configuration. It might harm the switched network and the distribution applications.
The analyzer compares the GOOSE control block references of the received GOOSE
messages (packets) with those in the SCD. In normal status, all references conform to
the values in the configuration description.
When a GOOSE control block reference is not listed in the active configuration, the
analyzer issues a specific diagnostic event to warn users of the status transition.
Statistic analyzer
Network load and GOOSE load within the specific subnetwork determine the secure
operation of the communication system. The analyzer continuously calculates the network
load and GOOSE load of the subnetworks during the configured interval.
