8.1.2.7 Exclusion mode
Exclusion mode is on, when the value set with the Exclusion time parameter is higher than
zero. During the exclusion mode, new triggerings are ignored if the triggering reason is the
same as in the previous recording. The
Exclusion time parameter controls how long the
exclusion of triggerings of same type is active after a triggering. The exclusion mode only
applies to the analog and binary channel triggerings, not to periodic and manual
triggerings.
When the value set with the Exclusion time parameter is zero, the exclusion mode is
disabled and there are no restrictions on the triggering types of the successive recordings.
The exclusion time setting is global for all inputs, but there is an individual counter for
each analog and binary channel of the digital fault recorder, counting the remaining
exclusion time. The user can monitor the remaining exclusion time with the
Exclusion time
rem parameter of the corresponding analog or binary channel. The Exclusion time rem
parameter counts downwards.
8.1.3 Configuration
The user can configure the digital fault recorder with the PCM600 tool or any tool
supporting the IEC 61850 standard.
The user can enable or disable the digital fault recorder with the Operation parameter
under the Configuration/Digital fault recorder/General menu.
One analog signal type of the relay can be mapped to each of the analog channels of the
digital fault recorder. The mapping is done with the
Channel selection parameter of the
corresponding analog channel. The name of the analog channel is user-configurable. The
user can modify it by writing the new name to the
Channel id text parameter of the
corresponding analog channel.
Any external or internal digital signal of the relay which can be dynamically mapped can
be connected to the binary channels of the digital fault recorder. These signals can be, for
example, the start and trip signals from protection function blocks or the external binary
inputs of the relay. The connection is made with dynamic mapping to the binary channel
of the digital fault recorder using, for example,
SMT of PCM600. It is also possible to
connect several digital signals to one binary channel of the digital fault recorder. In that
case, the signals can be combined with logical functions, for example AND and OR. The
user can configure the name of the binary channel and modify it by writing the new name
to the
Channel id text parameter of the corresponding binary channel.
Note that the Channel id text parameter is used in COMTRADE configuration files as a
channel identifier.
The recording always contains all binary channels of the digital fault recorder. If one of
the binary channels is disabled, the recorded state of the channel is continuously FALSE
and the state changes of the corresponding channel are not recorded. The corresponding
channel name for disabled binary channels in the COMTRADE configuration file is
Unused BI.
To enable or disable a binary channel of the digital fault recorder, the user can set the
Operation parameter of the corresponding binary channel to the values “ on ” or “ off ” .
