Operation principle

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:
• Sequential of events (SOE)
• Indications (IND)
• Event recorder (ER)
• Trip value recorder (TVR)
• Disturbance recorder (DR)
• Settings information
Figure 223 shows the relations between Disturbance Report, included functions and
function blocks. Sequential of events (SOE), 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). Disturbance recorder DRPRDRE acquires information from both
AxRADR and BxRBDR.
