Protocol Verification for Relays With IEC 61850 Option
Step 14. Issue the METER command; verify that the current and
voltage signals are correct.
Step 15. Autoconfigure the SEL-2032, SEL-2030, or SEL-2020 port if
you have a communications processor connected.
This step re-establishes automatic data collection between the
SEL-2032, SEL-2030, or SEL-2020 Communications
Processor and the SEL relay. Failure to perform this step can
result in automatic data collection failure when cycling
communications processor power.
Protocol Verification for Relays With IEC 61850 Option
Perform the following steps to verify that the IEC 61850 protocol is still
operational after a relay firmware upgrade and if not, re-enable it. This
procedure assumes that IEC 61850 was operational with a valid CID file
immediately before initiating the relay firmware upgrade.
Step 1. Establish an FTP connection to the relay Ethernet port.
Step 2. Open the ERR.TXT file.
If the ERR.TXT file is empty, the relay found no errors during
CID file processing and IEC 61850 should be enabled. Go to
Step 3 if ERR.TXT is empty.
If the ERR.TXT file contains error messages relating to CID
file parsing, the relay has disabled the IEC 61850 protocol. Use
ACSELERATOR
®
Architect
™
SEL-5032 Software to convert the
existing CID file and make it compatible again.
a. Install the Architect software upgrade that supports
your required CID file version.
b. Run Architect and open the project that contains the
existing CID file for the relay.
c. Download the CID file to the relay.
Step 3. Upon connecting to the relay, Architect detects the upgraded
relay firmware and prompts you to allow it to convert the
existing CID file to a supported version. Once converted,
downloaded, and processed, the valid CID file allows the relay
to re-enable the IEC 61850 protocol.
Step 4. In the Telnet session, type GOO <Enter>.
Step 5. View the GOOSE status and verify that the transmitted and
received messages are as expected.
The relay is now ready for your commissioning procedure.
NOTE: A relay with optional IEC
61850 protocol requires the presence
of one valid CID file to enable the
protocol. You should only transfer a
CID file to the relay if you want to
implement a change in the IEC 61850
configuration or if new relay firmware
does not support the current CID file
version. If you transfer an invalid CID
file, the relay disables the IEC 61850
protocol, because it no longer has a
valid configuration. To restart IEC
61850 protocol operation, you must
transfer a valid CID file to the relay.
