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
• Indications
• Event recorder
• Trip value recorder
• Disturbance recorder
• Fault locator (FL)
Figure 298 shows the relations between Disturbance Report, included functions and
function blocks. Sequential of events , Event recorder and Indications uses information
from the binary input function blocks (BxRBDR). Trip value recorder 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.
