Maintenance release of Relion® 670 series version 2.2 (2.2.1.1)

2017-12-21
Dear Reader,

A new revision of Relion® 670 series version 2.2 has been released. The new revision designation is 2.2.1.1.

The following has been corrected / improved in the new revision:

System and security related

  • ICMP Ping of IED when in maintenance mode
    When activating FTP server in maintenance menu, ICMP Ping is now activated. This enables the user to know that the IP addresses are configured correctly even when in maintenance mode.

  • Improved Internal Relay Failure (IRF) supervision
    Checks on missing GTM/IRIG-B/SLM/RS485 results in IRF being activated. This offers improved self-supervision when modules that were configured but were removed or failed.

  • IEC 61850 Ed2 data object Beh
    The data object Beh on logical nodes now reflects correctly according to IEC 61850 Ed2.

  • LPHD.PhyHealth when IED is reconfigured
    When the IED is reconfigured, the LHPD.PhyHealth is now shown correctly. An issue when using PCM600 write is now corrected.

  • Incorrect time stamp handling on received GOOSE
    Received GOOSE messages were recorded with incorrect time stamps, this lead to incorrect time stamps on received signals and potentially these signals were outside the disturbance recording.

  • IP addresses with leading zeros
    When IP addresses were entered with leading zeros it was interpreted as the octal equivalent instead of decimal.

  • Improved robustness at start-up
    The start-up blocking is now extended to cover two system frequency operating cycles.
Application related
  • Line differential protection using redundant channels
    When line differential protection uses the redundant channel for communication, a restart of an IED in the protected scheme can cause a mal-operation since the restarted IED for a short while uses data from the primary channel. The synchronization of data between the primary and redundant channel has now been improved.

  • Line differential communication out-of-service mode
    When the line differential communication is in out-of-service mode, a restart of the remote IED can be delayed.

  • Control commands to process devices
    When commands were routed through the XLNPROXY function it always resulted in a positive acknowledge although the command could have failed.

  • QCBAY functionality
    When the parameter RemoteIncStation is set, the command is issued if the LR-switch is set to Remote state, this is allowed both from station and remote levels without any priority.

  • LPTTR function in RER670
    When the measured temperature from sensors goes outside the range, it is set to the closest limit value (either SensorMinTemp or SensorMaxTemp). Earlier the DefaultAmbTemp was used when the measured temperature was outside the range.

  • Reset of open CT condition in transformer differential function
    Once the open CT condition is detected, it will not be reset by internal/external fault detection or if the bias current is increased over the limit.
