Disturbance report

Functionality

Complete and reliable information about disturbances in the primary and/or in the
secondary system together with continuous event-logging is accomplished by the
disturbance report functionality.
Disturbance report DRPRDRE, always included in the IED, acquires sampled data of
all selected analog input and binary signals connected to the function block with a,
maximum of 40 analog and 96 binary signals.
The Disturbance report functionality is a common name for several functions:
• Event list
• Indications
• Event recorder
• Trip value recorder
• Disturbance recorder
The Disturbance report function is characterized by great flexibility regarding
configuration, starting conditions, recording times, and large storage capacity.
A disturbance is defined as an activation of an input to the AnRADR or BnRBDR
function blocks, which are set to trigger the disturbance recorder. All connected
signals from start of pre-fault time to the end of post-fault time will be included in the
recording.
Every disturbance report recording is saved in the IED in the standard Comtrade
format as a reader file HDR, a configuration file CFG, and a data file DAT. The same
applies to all events, which are continuously saved in a ring-buffer. The local HMI is
