Disturbance report DRPRDRE is a common name for several functions to supply
the operator, analysis engineer, and so on, with sufficient information about events
in the system.
The functions included in the disturbance report are:
• Event list (EL)
• Indications (IND)
• Event recorder (ER)
• Trip value recorder (TVR)
• Disturbance recorder (DR)
• Fault locator (FL)
• Settings information
Figure
308 shows the relations between Disturbance Report, included functions
and function blocks. Event list (EL), Event recorder (ER) and Indications (IND)
uses information from the binary input function blocks (BxRBDR). Trip value
recorder (TVR) uses analog information from the analog input function blocks
(AxRADR) which is used by FL after estimation by TVR. Disturbance recorder
DRPRDRE acquires information from both AxRADR and BxRBDR.
