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), Event list (EL), 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.
