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:
• Sequential of events
• Indications
• Event recorder
• Trip value recorder
• Disturbance recorder
The Disturbance report function is characterized by great flexibility regarding
configuration, initiating conditions, recording times, and large storage capacity.
A disturbance is defined as an activation of an input to the AxRADR or BxRBDR
function blocks, which are set to trigger the disturbance recorder. All 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. The same applies to all events, which are continuously saved in a FIFO-buffer.
The local HMI is used to get information about the recordings. The disturbance report
files may be uploaded to PCM600 for further analysis using the disturbance handling
tool.
