Operation
The operation of Disturbance report function DRPRDRE has to be set
Disabled is selected, note that no disturbance report is registered, and none sub-function will
operate (the only general parameter that influences Sequential of events (SOE)).
Operation = Disabled :
• Disturbance reports are not stored.
• LED information (yellow - pickup, red - trip) is not stored or changed.
Operation = Enabled :
• Disturbance reports are stored, disturbance data can be read from the local HMI and from a
PC using PCM600.
• LED information (yellow - pickup, red - trip) is stored.
Every recording will get a number (0 to 999) which is used as identifier (local HMI, disturbance
handling tool and IEC 61850). An alternative recording identification is date, time and sequence
number. The sequence number is automatically increased by one for each new recording and is
reset to zero at midnight. The maximum number of recordings stored in the IED is 100. The oldest
recording will be overwritten when a new recording arrives (FIFO).
