Monitoring
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.
15.6.4 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 are 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)).
Figure 161
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 the analog input
function blocks (AxRADR), which is used by Fault locator (FL) after estimation by Trip Value
Recorder (TVR). Disturbance report function acquires information from both AxRADR and BxRBDR.
