16.6 Disturbance report DRPRDRE IP14584-1 v216.6.1 IdentificationM16055-1 v7Function description IEC 61850 identification IEC 60617identificationANSI/IEEE C37.2device numberDisturbance report DRPRDRE - -Disturbance report A1RADR - A4RADR - -Disturbance report B1RBDR - B22RBDR - -16.6.2 Application M12152-3 v7To get fast, complete and reliable information about disturbances in the primary and/or in thesecondary system it is very important to gather information on fault currents, voltages andevents. It is also important having a continuous event-logging to be able to monitor in an overviewperspective. These tasks are accomplished by the disturbance report function DRPRDRE andfacilitate a better understanding of the power system behavior and related primary and secondaryequipment during and after a disturbance. An analysis of the recorded data provides valuableinformation 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 perspectivewhen planning for and designing new installations, that is, a disturbance recording could be a partof 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• 352 binary signalsDisturbance report function is a common name for several functions that is, Indications (IND),Event recorder (ER), Sequential of events (SOE), Trip value recorder (TVR), Disturbance recorder(DR) and Fault locator (FL).Disturbance report function is characterized by great flexibility as far as configuration, startingconditions, recording times, and large storage capacity are concerned. Thus, disturbance report isnot dependent on the operation of protective functions, and it can record disturbances that werenot discovered by protective functions for one reason or another. Disturbance report can be usedas an advanced stand-alone disturbance recorder.Every disturbance report recording is saved in the IED. The same applies to all events, which arecontinuously 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 using FTPor MMS (over 61850–8–1) clients.Section 16 1MRK 511 358-UUS AMonitoring434Application manual
