16.6.2 Functionality M12153-3 v13Complete and reliable information about disturbances in the primary and/or in thesecondary system together with continuous event-logging is accomplished by thedisturbance report functionality.Disturbance report (DRPRDRE), always included in the IED, acquires sampled data ofall selected analog input and binary signals connected to the function block with amaximum of 40 analog and 352 binary signals.The Disturbance report functionality is a common name for several functions:• Sequential of events• Indications• Event recorder• Trip value recorder• Disturbance recorder• Settings informationThe Disturbance report function is characterized by great flexibility regardingconfiguration, initiating conditions, recording times, and large storage capacity.A disturbance is defined as an activation of an input to the AnRADR or BnRBDRfunction blocks, which are set to trigger the disturbance recorder. All connected signalsfrom pickup of pre-fault time to the end of post-fault time will be included in therecording. Disturbance record will have visible settings from all function instances thatare configured in the application configuration tool.Every disturbance report recording is saved in the IED in the standard Comtradeformat as a reader file HDR, a configuration file CFG, and a data file DAT. The sameapplies to all events, which are continuously saved in a ring-buffer. The local HMI isused to get information about the recordings. The disturbance report files can beuploaded to PCM600 for further analysis using the disturbance handling tool.16.6.3 Function block IP806-1 v1M12510-3 v3DRPRDREDRPOFFRECSTARTRECMADECLEAREDMEMUSEDIEC05000406-3-en.vsdIEC05000406 V3 EN-USFigure 219: DRPRDRE function block1MRK 511 408-UUS A Section 16MonitoringPhasor measurement unit RES670 2.2 ANSI 553Technical manual
