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; 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 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
