Operation
The operation of Disturbance report function DRPRDRE has to be set Enabled or
Disabled. If 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 for example 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).
To be able to delete disturbance records, Operation parameter has to be
Enabled.
The maximum number of recordings depend on each recordings total
recording time. Long recording time will reduce the number of recordings
to less than 100.
The IED flash disk should NOT be used to store any user files. This might
cause disturbance recordings to be deleted due to lack of disk space.
