Station Communication - ABB REL650 Product Manual

Line distance protection REL650 ANSI
Product version: 1.3
If normal FTP is required to read out
disturbance recordings, create a specific
account for this purpose with rights only to do
File transfer. The password of this user will be
exposed in clear text on the wire.
Generic security application AGSAL
As a logical node AGSAL is used for monitoring security violation
regarding authorization, access control and inactive association
including authorization failure. Therefore, all the information in
AGSAL can be configured to report to 61850 client.
Activity logging ACTIVLOG
ACTIVLOG contains all settings for activity logging.
There can be 6 external log servers to send syslog events to. Each
server can be configured with IP address; IP port number and
protocol format. The format can be either syslog (RFC 5424) or
Common Event Format (CEF) from ArcSight.
Security alarm SECALARM
The function creates and distributes security events for mapping
the security events on protocols such as DNP3.
It is possible to map respective protocol to the signals of interest
and configure them for monitoring with the Communication
Management tool (CMT) in PCM600. No events are mapped by
default.
Parameter names:
• EVENTID: Event ID of the generated security event
• SEQNUMBER: Sequence number of the generated security
event
Security events
All user operations are logged as events. These events can be
sent to external security log servers using SYSLOG data
formats. The log servers can be configured using PCM600.

16. Station communication

IEC 61850-8-1 communication protocol
The IED supports the communication protocols IEC 61850-8-1
and DNP3 over TCP/IP. All operational information and controls
are available through these protocols. However, some
32
communication functions, for example, horizontal communication
(GOOSE) between the IEDs, is only enabled by the IEC 61850-8-1
communication protocol.
The IED is equipped with optical Ethernet rear port(s) for the
substation communication standard IEC 61850-8-1. IEC
61850-8-1 protocol allows intelligent electrical devices (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.
Disturbance files are accessed using the IEC 61850-8-1 protocol.
Disturbance files are also available to any Ethernet based
application via FTP in the standard Comtrade format. Further, the
IED can send and receive binary values, double point values and
measured values (for example from MMXU functions), together
with their quality bit, using the IEC 61850-8-1 GOOSE profile. The
IED meets the GOOSE performance requirements for tripping
applications in substations, as defined by the IEC 61850
standard. The IED interoperates with other IEC 61850-compliant
IEDs, and systems and simultaneously reports events to five
different clients on the IEC 61850 station bus.
The Denial of Service functions DOSLAN1 and DOSFRNT are
included to limit the inbound network traffic. The communication
can thus never compromise the primary functionality of the IED.
The event system has a rate limiter to reduce CPU load. The event
channel has a quota of 10 events/second after the initial 30
events/second. If the quota is exceeded the event channel
transmission is blocked until the event changes is below the
quota, no event is lost.
All communication connectors, except for the front port
connector, are placed on integrated communication modules.
The IED is connected to Ethernet-based communication systems
via the fibre-optic multimode LC connector(s) (100BASE-FX).
The IED supports SNTP and IRIG-B time synchronization
methods with a time-stamping accuracy of ±1 ms.
• Ethernet based: SNTP and DNP3
• With time synchronization wiring: IRIG-B
The IED supports IEC 60870-5-103 time synchronization
methods with a time stamping accuracy of ±5 ms.
