Figure 158: SDAOGGIO Function Block
This module combines the outputs from the AutoRecloser function and the “Active Phase
Detect” function to route the TRIP / RECLOSE / LOCKOUT signals to the phases that are
active for the reclose cycle in progress currently.
The autorecloser function requires a single “Pole Status” signal for its internal needs.
However, the SDARREC function can allow operations on more than one phase at a time.
Two or three phases can be active at the same time.
When more than one pole is active, the SDAOGGIO will generate an equivalent “pole
status” signal for the AutoReclose function. Although all the TRIP / RECLOSE
commands are issued simultaneously, one pole may operate with a delay compared to the
other(s). In such cases, the SDAOGGIO will wait for all the active poles to complete their
transition before generating a valid status to be used by the AutoRecloser function.
5.2.5 Zone sequence coordination
Zone sequence coordination is used in the zone sequence between local protection units
and downstream devices. At the falling edge of the INC_SHOTP line, the value of the shot
pointer is increased by one, unless a shot is in progress or the shot pointer already has the
maximum value.
The falling edge of the INC_SHOTP line is not accepted if any of the shots are in progress.
Settings:
timeUnsuccessfulCB = value
Three phase lockout override = Disabled or Enabled
