Technical manual

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 352 binary signals.

The Disturbance report functionality is a common name for several functions:

Sequential of events

Event recorder

Trip value recorder

Disturbance recorder

Settings information

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 AnRADR or BnRBDR

function blocks, which are set to trigger the disturbance recorder. All connected signals

from pickup 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.
