IEC 61850 allows IEDs to be directly configured from a configuration file. The IED's system configuration
capabilities are determined from an IED Capability Description file (ICD), supplied with the product. By using ICD
files from the products to be installed, you can design, configure and test (using simulation tools), a substation's
entire protection scheme before the products are installed into the substation.
To help with this process, the settings application software provides an IEC 61850 Configurator tool, which allows
the pre-configured IEC 61850 configuration file to be imported and transferred to the IED. As well as this, you can
manually create configuration files for all products, based on their original IED capability description (ICD file).
Other features include:
The extraction of configuration data for viewing and editing.
A sophisticated error checking sequence to validate the configuration data before sending to the IED.
Some configuration data is available in the IEC61850 CONFIG. column, allowing read-only access to basic configuration data.
IEC 61850 CONFIGURATION BANKS
There are two configuration banks:
Active Configuration Bank
Inactive Configuration Bank
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.
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.
