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 canrecord disturbances that were not discovered by protective functions for one reason oranother. 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 informationabout the recordings, and the disturbance report files may be uploaded in the PCM600using the Disturbance handling tool, for report reading or further analysis (usingWaveWin, that can be found on the PCM600 installation CD). The user can also uploaddisturbance 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 (recordmade and fault number) and the fault locator information are available as GOOSE orReport Control data.12.7.3 Setting guidelinesThe setting parameters for the Disturbance report function DRPRDRE are set via the localHMI or PCM600.It is possible to handle up to 40 analog and 96 binary signals, either internal signals orsignals coming from external inputs. The binary signals are identical in all functions thatis, Disturbance recorder, Event recorder, Indication, Trip value recorder and Sequential ofevents function.User-defined names of binary and analog input signals is set using PCM600. The analogand binary signals appear with their user-defined names. The name is used in all relatedfunctions (Disturbance recorder, Event recorder, Indication, Trip value recorder andSequential of events ).Figure 134 shows the relations between Disturbance report, included functions andfunction blocks. Sequential of events , Event recorder and Indication uses informationfrom the binary input function blocks (BxRBDR). Trip value recorder uses analoginformation from the analog input function blocks (AxRADR),. Disturbance reportfunction acquires information from both AxRADR and BxRBDR.Section 12 1MRK 511 286-UUS AMonitoring296Application manual
