DIRECTIONAL COMPARISON BLOCKING1
(DCB1) scheme is designed to operate exactly same way as regular Directional
Comparison Blocking (DCB) scheme, except hard-coded connections to phase and ground distance elements are removed
to allow the user to choose FlexLogic Operands to identify forward or reverse direction fault, such as ground OC directional
elements for example. This gives the user more flexibility and better coordination when employing this scheme.
Figure 5–171: DIRECTIONAL COMPARISON BLOCKING1 SCHEME LOGIC
Settings description and application guidance for DCB scheme are fully applicable to DCB1 scheme with the following
exceptions.
BLK1 SCHME DIR FWD1-3
: Each setting defines the FlexLogic operand of a protection element for identifying forward faults on
the protected line, and thus, for initiating operation of the scheme. Good directional integrity is the key requirement for an
over-reaching forward-looking protection element.
Even though any FlexLogic operand can be used as
BLK1 SCHME DIR FWD
enabling the user to combine responses of vari-
ous protection elements or to apply extra conditions through FlexLogic equations,
BLK1 SCHME DIR FWD
entries are primarily
meant to be the output operand from the Negative-Sequence Directional FWD IOC, Neutral Directional FWD IOC, and the
forward-looking distance over-reaching elements.
BLK1 SCHME DIR REV1-3
: This setting defines the FlexLogic operand of a protection element that is used for identifying
reverse faults, and thus, for initiating the blocking signal. Reverse-looking directional overcurrent protection elements or
reverse-looking distance elements can be used as
BLK1 SCHME DIR REV
.
Even though any FlexLogic operand can be used as
BLK1 SCHME DIR REV
enabling the user to combine responses of vari-
ous protection elements or to apply extra conditions through FlexLogic equations,
BLK1 SCHME DIR REV
entries are primarily
meant to be the output operand from the Negative-Sequence Directional REV IOC, Neutral Directional REV IOC, non-
directional IOC, or reverse-looking distance elements.
Coordinate the selected protection element (or elements in combination) with the selection of DIR FWD. For all the forward
external faults seen by an element used as
BLK1 SCHME DIR FWD
at one end of the line, the reverse-looking element used
as
BLK1 SCHME DIR REV
at the other end picks up and provides a blocking signal.
