4.1
615 series implementation
The IEC 61850 communication protocol is always supported by the 615 series
IEDs. If the IED 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 by using IEC 61850 via the front Ethernet port of the
LHMI. Without the Ethernet option, event reporting or peer-to-peer services cannot
be used.
Only one point-to-point connection is allowed to the front port.
This means that no network can be built by using the front port.
The 615 series has been designed to fully support the concepts of IEC 61850. This
means that any information and data offered by the 615 series IEDs can be
modelled according to IEC 61850 and the services for using the data are widely
supported according to the standard.
•
Process data: monitoring of status information, measurements
•
Application data: protection activations, tripping, fault recordings
•
Disturbance recorder files
•
Control commands
•
Protection settings
•
Setting groups
•
Configuration data
•
Self-supervision messages
•
Fast horizontal communication between devices
•
Time synchronization
4.2
Information model
According to the IEC 61850 model, a 615 series IED consists of three logical devices.
•
Control logical device, CTRL
•
Disturbance recorder logical device, DR
•
Protection logical device, LD0
Generic functionality, such as physical inputs and outputs as well as the alarming
LED functionality, resides under LD0.
