Technical manual
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 352 binary signals.
The Disturbance report functionality is a common name for several functions:
• Event list
• Indications
• Event recorder
• Trip value recorder
• Disturbance recorder
• Fault locator
• Settings information
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. Disturbance record will have visible settings from all function
instances that are configured in the application configuration tool.
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 used to get information about the recordings. The disturbance report files
can be uploaded to PCM600 for further analysis using the disturbance handling
tool.
