EXAMPLE 2: PILOT-AIDED SCHEMES
Consider a three-terminal line protection application shown in the figure below.
Figure 5–67: 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 5–68: 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:
"2"
DIRECT OUT 2 OPERAND:
"
HYB POTT TX1
"
DIRECT OUT 3 OPERAND:
"
DIRECT INPUT 5
" (forward a message from 1 to 3)
DIRECT OUT 4 OPERAND:
"
DIRECT INPUT 6
" (forward a message from 3 to 1)
