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.
18.6.3 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 Sequential of events (SOE) 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 Sequential of events (SOE)).
Figure
396 shows the relations between Disturbance report, included functions and
function blocks. Sequential of events (SOE), 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.
