It is also important having a continuous event-logging to be able to monitor in an overview perspective. These tasks areaccomplished by the disturbance report function DRPRDRE and facilitate a betterunderstanding of the power system behavior and related primary and secondaryequipment during and after a disturbance. An analysis of the recorded dataprovides valuable information that can be used to explain a disturbance, basis forchange of IED setting plan, improve existing equipment, and so on. Thisinformation can also be used in a longer perspective when planning for anddesigning new installations, that is, a disturbance recording could be a part ofFunctional Analysis (FA).Disturbance report DRPRDRE, always included in the IED, acquires sampled dataof all selected analog 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; 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 asconfiguration, starting conditions, recording times, and storage capacity areconcerned. Thus, disturbance report is not dependent on the operation of protectivefunctions, and it can record disturbances that were not discovered by protectivefunctions for one reason or another. Disturbance report can be used as an advancedstand-alone disturbance recorder.Section 16 1MRK 511 407-UEN CMonitoring270 Phasor measurement unit RES670 2.2 IECApplication manual
