Operation principle
The denial of service functions (DOSLAN1 and DOSFRNT) measures the IED
communication load and, if necessary, limit it to avoid compromising the IEDs
control and protection functionality due to high CPU load. The function has three
outputs.
•
LINKUP indicates the Ethernet link status
•
WARNING indicates that communication (frame rate) is higher than normal
•
ALARM indicates that the IED limits communication
IEC 61850-8-1 communication protocol
Functionality
IEC 61850-8-1 protocol allows IEDs from different vendors to exchange information
and simplifies system engineering. Peer-to-peer communication according to
GOOSE is part of the standard. Disturbance files uploading is provided.
The event system has a rate limiter to reduce CPU load. Each channel has a quota of
10 events/second. If the quota is exceeded the event channel is blocked until the event
changes is below the quota.
