It is also important having a continuous event-logging to be able to monitor in anoverview perspective. These tasks are accomplished by the disturbance report functionDRPRDRE and facilitate a better understanding of the power system behavior and relatedprimary and secondary equipment during and after a disturbance. An analysis of the recordeddata provides valuable information that can be used to explain a disturbance, basis for changeof IED setting plan, improve existing equipment, and so on. This information can also be usedin a longer perspective when planning for and designing new installations, that is, adisturbance recording could be a part of Functional Analysis (FA).Disturbance report DRPRDRE, always included in the IED, acquires sampled data of all selectedanalog and binary signals connected to the function blocks that is,• Maximum 30 external analog signals,• 10 internal derived analog signals, and• 128 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).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, whichare continuously saved in a ring-buffer. Local HMI can be used to get information about therecordings, and the disturbance report files may be uploaded in the PCM600 using theDisturbance handling tool, for report reading or further analysis (using WaveWin, that can befound on the PCM600 installation CD). The user can also upload disturbance report files usingFTP or MMS (over 61850–8–1) clients.If the IED is connected to a station bus (IEC 61850-8-1), the disturbance recorder (record madeand fault number) and the fault locator information are available. The same information isobtainable if IEC 60870-5-103 is used.12.5.3 Setting guidelines IP14874-1 v1M12179-64 v7The setting parameters for the Disturbance report function DRPRDRE are set via the local HMIor PCM600.It is possible to handle up to 40 analog and 128 binary signals, either internal signals or signalscoming from external inputs. The binary signals are identical in all functions that is,Section 12 1MRK 505 355-UEN AMonitoring214Application manual
