Technical manual
During post processing of the disturbance record, the header file is updated with a
section called Settings . Settings has complete setting values of the configured
components that are read during the trigger time. The setting values, runtime status and
the behavior of each component are compared between the trigger and the post
processing time. If there are any differences, then it will be added in the header file
under section Changed_settings.
In the HDR file, section tag Settings has an attribute tag called function which includes
parameters that are grouped based on the function instance. The function tag has
content called name which is the function name provided together with the user-
defined name in brackets similar to the HMI. Status content will indicate the runtime
status of the function and beh content will indicate the IEC61850 behavior of the
components, if supported. Non runtime components will not have status and beh tag
contents.
Parameters of the function are listed as a child tag Set with contents name, value and
unit:
• name — parameter name same as HMI
• value — actual parameter value
• unit — parameter unit
The changed_settings attribute tag is similar to the settings section. It contains
functions which have changes in parameter value or runtime status or IEC61850
behavior when compared with trigger and post-processing settings values.
Time tagging
The IED has a built-in real-time calendar and clock. This function is used for all time
tagging within the disturbance report
Recording times
Disturbance report DRPRDRE records information about a disturbance during a
settable time frame. The recording times are valid for the whole disturbance report.
Disturbance recorder (DR), event recorder (ER) and indication function register
disturbance data and events during tRecording, the total recording time.
The total recording time, tRecording, of a recorded disturbance is:
tRecording = PreFaultrecT + tFault + PostFaultrecT or PreFaultrecT + TimeLimit , depending on
which criterion stops the current disturbance recording
