Disturbance report function is a common name for several functions that is, Indications,
Event recorder, Sequential of events, Trip value recorder, Disturbance recorder and Fault
locator (FL).
Disturbance report function is characterized by great flexibility as far as configuration,
starting conditions, recording times, and large storage capacity are concerned. Thus,
disturbance report is not dependent on the operation of protective functions, and it can
record disturbances that were not discovered by protective functions for one reason or
another. Disturbance report can be used as an advanced stand-alone disturbance recorder.
Every disturbance report recording is saved in the IED. The same applies to all events,
which are continuously saved in a ring-buffer. Local HMI can be used to get information
about the recordings, and the disturbance report files may be uploaded in the PCM600
using the Disturbance handling tool, for report reading or further analysis (using
WaveWin, that can be found on the PCM600 installation CD). The user can also upload
disturbance report files using FTP or MMS (over 61850–8–1) clients.
If the IED is connected to a station bus (IEC 61850-8-1), the disturbance recorder (record
made and fault number) and the fault locator information are available as GOOSE or
Report Control data.

Setting guidelines

The setting parameters for the Disturbance report function DRPRDRE are set via the local
HMI or PCM600.
It is possible to handle up to 40 analog and 96 binary signals, either internal signals or
signals coming from external inputs. The binary signals are identical in all functions that
is, Disturbance recorder, Event recorder, Indication, Trip value recorder and Sequential of
events function.
User-defined names of binary and analog input signals is set using PCM600. The analog
and binary signals appear with their user-defined names. The name is used in all related
functions (Disturbance recorder, Event recorder, Indication, Trip value recorder and
Sequential of events ).
Figure 210 shows the relations between Disturbance report, included functions and
function blocks. Sequential of events , Event recorder and Indication uses information
from the binary input function blocks (BxRBDR). Trip value recorder uses analog
information from the analog input function blocks (AxRADR), which is used by Fault
locator after estimation by Trip Value Recorder. Disturbance report function acquires
information from both AxRADR and BxRBDR.
