Iec 61850 Edition 2 - GE P4A Technical Manual

Chapter 17 - Communications
Any new configuration sent to the IED is automatically stored in the inactive configuration bank, therefore not
immediately affecting the current configuration.
Following an upgrade, the IEC 61850 Configurator tool can be used to transmit a command, which authorises
activation of the new configuration contained in the inactive configuration bank. This is done by switching the
active and inactive configuration banks. The capability of switching the configuration banks is also available using
the IEC61850 CONFIG. column of the HMI.
The SCL Name and Revision attributes of both configuration banks are available in the IEC61850 CONFIG. column
of the HMI.
7.4.10.2 IEC 61850 NETWORK CONNECTIVITY
Configuration of the IP parameters and SNTP (Simple Network Time Protocol) time synchronisation parameters is
performed by the IEC 61850 Configurator tool. If these parameters are not available using an SCL (Substation
Configuration Language) file, they must be configured manually.
Every IP address on the Local Area Network must be unique. Duplicate IP addresses result in conflict and must be
avoided. Most IEDs check for a conflict on every IP configuration change and at power up and they raise an alarm
if an IP conflict is detected.
The IED can be configured to accept data from other networks using the Gateway setting. If multiple networks are
used, the IP addresses must be unique across networks.

IEC 61850 EDITION 2

Many parts of the IEC 61850 standard have now been released as the second edition. This offers some significant
enhancements including:
Improved interoperability
●
● Many new logical nodes
Better defined testing; it is now possible to perform off-line testing and simulation of functions
●
Edition 2 implementation requires use of version 3.2 of the IEC 61850 configurator, which is installed with version
1.2 of MiCOM S1 Agile.
7.4.11.1 BACKWARD COMPATIBILITY
IEC61850 System - Backward compatibility
An Edition 1 IED can operate with an Edition 2 IEC 61850 system, provided that the Edition 1 IEDs do not subscribe
to GOOSE messages with data objects or data attributes which are only available in Edition 2.
