16.6.2 Application
To get fast, complete and reliable information about disturbances in the primary and/or in the
secondary system it is very important to gather information on fault currents, voltages and
events. It is also important having a continuous event-logging to be able to monitor in an overview
perspective. These tasks are accomplished by the disturbance report function DRPRDRE and
facilitate a better understanding of the power system behavior and related primary and secondary
equipment during and after a disturbance. An analysis of the recorded data provides valuable
information 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 perspective
when planning for and designing new installations, that is, a disturbance recording could be a part
of Functional Analysis (FA).
Disturbance report DRPRDRE, always included in the IED, acquires sampled data of 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 signals
Disturbance 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, starting
conditions, recording times, and large storage capacity are concerned. Thus, disturbance report is
not dependent on the operation of protective functions, and it can record disturbances that were
not discovered by protective functions for one reason or another. 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 information about the
recordings, and the disturbance report files may be uploaded in the PCM600 using the
Disturbance handling tool, for report reading or further analysis (using WaveWin, that can be
found on the PCM600 installation CD). The user can also upload disturbance report files using FTP
or MMS (over 61850–8–1) clients.
