3.24.3.4 Clearing of record
The load profile record can be cleared with
Reset load profile rec
via HMI,
communication or the ACT input in PCM600. Clearing of the record is allowed only
on the engineer and administrator authorization levels.
The load profile record is automatically cleared if the quantity selection parameters
are changed or any other parameter which affects the content of the COMTRADE
configuration file is changed. Also, if data source for selected quantity is removed,
for example, with ACT, the load profile recorder stops recording and previously
collected data are cleared.
3.24.4 Configuration
The load profile record can be configured with the PCM600 or any tool supporting
the IEC 61850 standard.
The load profile record can be enabled or disabled with the
Operation
setting under
the Configuration/Load Profile Record menu.
Any demand output can be connected to any of the quantity channels of the load
profile record. The mapping is done in Application Configuration in PCM600.
Figure 190: Example of a load profile record ACT configuration
The memory consumption of load profile record is supervised, and indicated
with two signals MEM_WARN and MEM_ALARM, which could be used to notify the
customer that recording should be backlogged by reading the recorded data from
the protection relay. The levels for MEM_WARN and MEM_ALARM are set by two
parameters
Mem.warn level
and
Mem. Alarm level
.
The IP number of the protection relay and the content of the Bay
name setting are both included in the COMTRADE configuration file for
identification purposes.
