Distance scheme test (if activated in MiCOM S1 Agile)

5.3.2.1

Control

• The type of distance scheme enabled in MiCOM S1 Agile
• The DDB cells assigned for the distance scheme
• Ref to the description feature in P44x/EN AP section "Distance protection schemes":
 Settings in S1
 DDB cells
 Internal logic in A2.10 & A3.2
REMINDER:
Note:
Input:(PSL by default "P&C ")

1. Select a mode.
2. Implement the fault indicated in the panel first column, the carrier signal input is
enabled (with carrier receive).
3. Check that the trip contact have been energised at the end of the time-delay indicated
in the same column (With carrier receive).
4. Repeat step 2 and 3 but without the carrier receive input and checking the indicated
time-delay in the panel's 2nd column (without carrier receive).
Repeat step 2 and 4 for the other faulted zones by checking that whatever the carrier receive
input state, the time-delays associated with every zone are not modified (according to the 4th
column equations)
Note:
General equation to the tripping in distance protection since A2.9/A3.1
– From A2.10/A3.2 it can be found in the Chap EN AP – section 2.5
Before testing, check the input presence / Output in PSL linked to the selected
channel-aided scheme (DDB: DistCR/Dist CS). Also check the I/O condition change
(on LCD in FAV in "system")
WHEN SWITCHING GROUPS VIA THE OPTO COUPLERS: OPTOS 1 AND
2 MUST NOT BE ASSIGNED IN THE PSL.

Channel-aided schemes can be simulated by inverting the optos
Channel-aided schemes transmissions can also be checked by generating defaults
according to the 3rd column.
To simplify the relay I/O control condition, the assignments of LEDs in the PSL can be
modified. It is also possible in MiCOM S1 Agile
Output: (PSL by default "P&C ")
