Testing Scheme Communication Functions; Testing Logic Functions; Tripping Logic, Common 3-Phase Output Smpptrc; Three-Phase Operating Mode - ABB REQ650 1.3 IEC Commissioning Manual

1MRK 505 293-UEN B
Values of the logical signals are available on the local HMI under Main menu/Tests/Function
status/Control/<Function>/<Function:1>. The Signal Monitoring in PCM600 shows the same
signals that are available on the local HMI.
The interlocking function consists of a bay-level part and a station-level part. The interlocking
is delivery specific and is realized by bay-to-bay communication over the station bus. For that
reason, test the function in a system, that is, either in a complete delivery system as an
acceptance test (FAT/SAT) or as parts of that system.

Testing logic functions

7.9.1

Tripping logic, common 3-phase output SMPPTRC

Prepare the IED for verification of settings as outlined in section
settings.
Values of the logical signals for SMPPTRC are available on the local HMI under Main menu/
Tests/Function status/Logic/SMPPTRC(94,1->0)/SMPPTRC:X. The Signal Monitoring in
PCM600 shows the same signals that are available on the local HMI.
This function is functionality tested together with other protection functions (earth-fault
overcurrent protection, and so on) within the IED. It is recommended that the function is
tested together with the autorecloser function, regardless of whether the autorecloser
function is integrated or external.
7.9.1.1

Three-phase operating mode

1. Check that
2. Initiate a three-phase fault.
An adequate time interval between the faults should be considered, to overcome a
reclaim time caused by the possible activation of the Autorecloser function, SMBRREC.
The function must issue a three-phase trip in all cases, when a trip is initiated by any
protection function, either integrated or external. The functional TRIP output signal must
always appear.
7.9.1.2

Circuit breaker lockout

The following tests should be carried out when the built-in lockout function is used in addition
to possible other tests, which depends on the complete configuration of an IED.
1. Check that
2. Initiate a three-phase fault.
The functional output TRIP should be active at each fault. The output CLLKOUT must not
be activated.
3. Activate the automatic lockout function, set
Besides the TRIP outputs, CLLKOUT should be set.
4. Reset the lockout signal by activating the reset lockout (RSTLKOUT) signal.
5. Activate the TRIP signal lockout function, set
The output TRIP must be active and stay active after each fault. CLLKOUT must be
activated.
6. Reset the lockout.
