Date Code 20151029 Protection Manual SEL-411L Relay
Firmware and Manual Versions
Firmware
➤ Revised echo-conversion-to-trip logic to properly assert single-pole
trip for weak-infeed conditions when ECOMM = POTT OR
ECOMM = POTT2 and EWFC = SP. Previous firmware revisions
will not high-speed single-pole trip under these conditions.
➤ Added setting E87PG to allow the 87L Port settings to be visible
in the group settings.
➤ Enhanced the lost packet count to ignore a jump in relay time
received from the IRIG-B signal. In previous firmware, a step
change in the received time could result in an increase in the lost
packet count.
➤ Updated new bay screens to allow longer name lengths.
➤ Enhanced channel-based synchronization to be more resilient
against loss of external time. In previous firmware, intermittent
IRIG-B signals could cause momentary loss of channel
synchronization when the relay was using a channel-based
synchronization mode.
➤ Enhanced performance to ensure that the relay re-synchronizes
to IRIG-B after receipt of a corrupted IRIG signal.
➤ Added extra directional supervision to high-speed quadrilateral
ground and phase distance elements. This enhancement applies
to the SEL-411L-1 relay only.
➤ Enhanced performance to ensure that the relay does not become
unresponsive when M
IRRORED BITS is used on the front port. In
all previous firmware revisions, the relay could become
unresponsive if the front EIA-232 port is set to M
IRRORED BITS
protocol.
➤ Enhanced performance of the 87L Test Mode Supervision. In
previous firmware, under certain conditions, the relay could stay
in test mode even if the test supervision is not true.
➤ Revised firmware to ensure IEC 61850 GOOSE messages with
VLAN = 0 are properly transmitted.
SEL-411L-R111-V0-Z006002-D20131021
SEL-411L-1-R111-V0-Z006002-D20131021
➤ Improved traveling wave fault location accuracy.
➤ Added ability to configure IEDs through a single CID file.
➤ Corrected GOOSE time attribute to match SER.
➤ Modified DNPCL to disable analog output control in addition to
the binary output controls.
➤ Corrected issue where relay can become unresponsive while
using the Test DB2 on RLYDIS DNP point.
➤ Increased number of buffered and unbuffered reports to seven
for MMS reporting.
➤ Added support for MMS authentication.
➤ Added MMS file transfer.
20131021
➤ Added support for user-selectable GOOSE filtering.
➤ Added new group settings, TWFLIF and TWCOMI, for
traveling wave enhancement.
➤ Added Parallel Redundancy Protocol (PRP).Corrected group
settings range for TWLL and LPVEL.
➤ Closed an outgoing UDP port that was reported as open by a
port scanner when IEC 61850 was enabled.
➤ Fixed issue where relay could become unresponsive when long
strings were used in front-panel settings.
➤ Enhanced the HIS command to display the best available fault
location result based on the CONFLOC analog quantity.
