5.2 PRODUCT SETUP
In the above application, the following settings should be applied:
UR IED 1:
DIRECT OUTPUT DEVICE ID:
DIRECT I/O RING CONFIGURATION:
UR IED 3:
DIRECT OUTPUT DEVICE ID:
DIRECT I/O RING CONFIGURATION:
In this configuration the following delivery times are expected (at 128 kbps):
IED 1 to IED 2: 0.2 of power system cycle; IED 1 to IED 3: 0.5 of power system cycle;
IED 2 to IED 3: 0.2 of power system cycle
In the above scheme, IEDs 1 and 3 do not communicate directly. IED 2 must be configured to forward the messages as
5 explained in the Inputs/Outputs section. A blocking pilot-aided scheme should be implemented with more security and, ide-
ally, faster message delivery time. This could be accomplished using a dual-ring configuration as shown below.
Figure 5–12: DUAL-CHANNEL CLOSED LOOP (DUAL-RING) CONFIGURATION
In the above application, the following settings should be applied:
UR IED 1:
DIRECT OUTPUT DEVICE ID:
DIRECT I/O RING CONFIGURATION:
UR IED 3:
DIRECT OUTPUT DEVICE ID:
DIRECT I/O RING CONFIGURATION:
In this configuration the following delivery times are expected (at 128 kbps) if both the rings are healthy:
IED 1 to IED 2: 0.2 of power system cycle; IED 1 to IED 3: 0.2 of power system cycle;
IED 2 to IED 3: 0.2 of power system cycle
The two communications configurations could be applied to both permissive and blocking schemes. Speed, reliability and
cost should be taken into account when selecting the required architecture.
