Now the three blocking signals are available in UR IED 1 as
DIRECT INPUT 7 ON
,
DIRECT INPUT 8 ON
, and
DIRECT INPUT 9
ON
. Upon losing communications or a device, the scheme is inclined to block (if any default state is set to “On”), or to trip
the bus on any overcurrent condition (all default states set to “Off”).
EXAMPLE 2: PILOT-AIDED SCHEMES
Consider a three-terminal line protection application shown in the figure below.
Figure 5–140: THREE-TERMINAL LINE APPLICATION
Assume the Hybrid Permissive Overreaching Transfer Trip (Hybrid POTT) scheme is applied using the architecture shown
below. The scheme output operand
HYB POTT TX1
is used to key the permission.
Figure 5–141: SINGLE-CHANNEL OPEN-LOOP CONFIGURATION
In the above architecture, Devices 1 and 3 do not communicate directly. Therefore, Device 2 must act as a ‘bridge’. The fol-
lowing settings should be applied:
UR IED 1:
DIRECT OUT 2 OPERAND:
"
HYB POTT TX1
"
DIRECT INPUT 5 DEVICE ID:
"2"
DIRECT INPUT 5 BIT NUMBER:
"2" (this is a message from IED 2)
DIRECT INPUT 6 DEVICE ID:
"2"
DIRECT INPUT 6 BIT NUMBER:
"4" (effectively, this is a message from IED 3)
UR IED 3:
DIRECT OUT 2 OPERAND:
"
HYB POTT TX1
"
DIRECT INPUT 5 DEVICE ID:
"2"
DIRECT INPUT 5 BIT NUMBER:
"2" (this is a message from IED 2)
DIRECT INPUT 6 DEVICE ID:
"2"
DIRECT INPUT 6 BIT NUMBER:
"3" (effectively, this is a message from IED 1)
UR IED 2:
DIRECT INPUT 5 DEVICE ID:
"1"
DIRECT INPUT 5 BIT NUMBER:
"2"
DIRECT INPUT 6 DEVICE ID:
"3"
DIRECT INPUT 6 BIT NUMBER:
