Application

To get fast, complete and reliable information about disturbances in the primary and/or in the
secondary system it is very important to gather information on fault currents, voltages and
events. It is also important having a continuous event-logging to be able to monitor in an
overview perspective. These tasks are accomplished by the disturbance report function
DRPRDRE and facilitate a better understanding of the power system behavior and related
primary and secondary equipment during and after a disturbance. An analysis of the recorded
data provides valuable information that can be used to explain a disturbance, basis for change
of IED setting plan, improve existing equipment, and so on. This information can also be used
in a longer perspective when planning for and designing new installations, that is, a
disturbance recording could be a part of Functional Analysis (FA).
Disturbance report DRPRDRE, always included in the IED, acquires sampled data of all selected
analog and binary signals connected to the function blocks that is,
• Maximum 30 external analog signals,
• 10 internal derived analog signals, and
• 352 binary signals
Disturbance report function is a common name for several functions that is, Indications (IND),
Event recorder (ER), Event list (EL), Trip value recorder (TVR), Disturbance recorder (DR) 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. The same information is obtainable if IEC60870-5-103 is used.

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 352 binary signals, either internal signals or signals
coming from external inputs. The binary signals are identical in all functions that is,
Disturbance recorder (DR), Event recorder (ER), Indication (IND), Trip value recorder (TVR) and
Event list (EL) 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 (DR), Event recorder (ER), Indication (IND), Trip value recorder (TVR) and
Event list (EL)).

blocks. Event list (EL), Event recorder (ER) and Indication (IND) uses information from the
binary input function blocks (BxRBDR). Trip value recorder (TVR) uses analog information from
