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; Indications
(IND), Event recorder (ER), Event list (EL), Trip value recorder (TVR), Disturbance
recorder (DR).
Disturbance report function is characterized by great flexibility as far as
configuration, starting conditions, recording times, and 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. The
same information is obtainable if IEC 60870-5-103 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)).
