StNum and SqNum are integers ranging from 1 to 4 294 967 295. If counter SqNum
overruns, it has to be set to 1.
The disorder analyzer verifies StNum and SqNum contained in the received GOOSE
message (packet) for each GOOSE control block. If counters for StNum and SqNum do
not behave serially as stated above, the analyzer treats it as a disorder and issues a specific
diagnostic event to warn users of the status transition.
DatSet structure analyzer
9.4.13.
DatSet structure represents the structure of members in the referenced data set.
The DatSet structure analyzer compares the structure contained in the received GOOSE
message (packet) with that in the SCD based on the reference of the GOOSE control
block. In normal status, the DatSet structure conforms to the value in the configuration.
When a DatSet structure mismatch is detected, the analyzer issues a specific diagnostic
event to warn users of the status transition.
Data changes analyzer
9.4.14.
The analyzer continuously monitors the data values in the received GOOSE message
(packet), comparing it with the corresponding recordings from the previous GOOSE
message. If the data changes analyzer detects a value change, it reports the change.
Statistic analyzer
9.4.15.
The analyzer traces GOOSE load from a specific GOOSE control block of the sending
IED.
The analyzer calculates the GOOSE load from the specific GOOSE control block refer-
ences during the configured interval.
For each interval, the analyzer sums up respectively:
•
Received GOOSE packets
•
Received GOOSE bytes
•
Received GOOSE events for users
