7.2.2.10 Exclusion mode
Exclusion mode is on, when the value set with the
higher than zero. During the exclusion mode, new triggerings are ignored if the
triggering reason is the same as in the previous recording. The
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
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 disturbance recorder, counting the
remaining exclusion time. The user can monitor the remaining exclusion time with
the
ExclTmRmn) of the corresponding analog or binary channel. The
parameter counts downwards.

Configuration

The disturbance recorder can be configured with PCM600 or any tool supporting
the IEC 61850 standard.
The disturbance recorder can be enabled or disabled with the
under the Configuration > Disturbance recorder > General menu.
One analog signal type of the merging unit can be mapped to each of the analog
channels of the disturbance recorder. The mapping is done with the
selection parameter of the corresponding analog channel. The name of the analog
channel is user-configurable. It can be modified by writing the new name to the
Channel id text parameter of the corresponding analog channel.
Any external or internal digital signal of the merging unit which can be dynamically
mapped can be connected to the binary channels of the disturbance recorder. These
signals can be, for example, the start and trip signals from protection function
blocks or the external binary inputs of the merging unit. The connection is made
with dynamic mapping to the binary channel of the disturbance recorder using,
for example, SMT of PCM600. It is also possible to connect several digital signals
to one binary channel of the disturbance recorder. In that case, the signals can be
combined with logical functions, for example AND and OR. The name of the binary
channel can be configured and modified by writing the new name to the
text parameter of the corresponding binary channel.
Note that the
a channel identifier.
The recording always contains all binary channels of the disturbance 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 an analog or a binary channel of the disturbance recorder, the
Operation parameter of the corresponding analog or binary channel is set to "on" or
"off".
