615 series data model
Product series implementation
The protection relays have been fully designed according to IEC 61850. This means
that the functionality of the protection relay is represented in a data model in
accordance with the standard and the protection relays support a wide range of the
services provided by the standard.
•
Process data: monitoring of statuses and measurements
•
Application data: protection activation, tripping, fault recordings
•
Disturbance records
•
Control commands
•
Protection settings
•
Settings and setting groups
•
Configuration data
•
Diagnostics and self-supervision
•
Fast horizontal communication between devices
•
Time synchronization
•
File transfer
As this series of relays supports both versions of IEC 61850, Edition 1 and Edition 2,
there are small differences with IEC 61850 data model depending of the used version.
Generally the relay's protection and control functionality is independent of the IEC
61850 version used. Any differences between data model versions are documented.
If the protection relay is ordered with no Ethernet communication interface, the front
port on the device still works according to IEC 61850. All settings and configurations
are changed with IEC 61850 services using PCM600 via the front Ethernet port of the
LHMI. Without the rear Ethernet option, station communication is not available.
Information model
The protection relay is fully modelled according to the IEC 61850 standard. The data
model can include up to four logical devices where different logical nodes,
representing protection and control functionality, are located. Depending on the
selected functionality in the protection relay, different configurations have different
set of logical devices and logical nodes. Data models also include full modelling and
functionality of setting, setting groups and configuration according to the IEC 61850
concept.
