The discrimination time ‘t Discrim 3P’ is also needed for 2 or 1?
breaker schemes, where each circuit-breaker has its own autoreclosure function.
A typical setting for the parameters ‘t Discrim 1P’ or ‘t Discrim
3P’ for single and three-phase reclosure is 50 % of the shortest
dead time.
The minimum permissible setting for the discrimination time is:
100 ms + CB time
Note:
The time ‘t1EvolFaults’ during which a subsequent fault has to
be detected (evolving or unsuccessful reclosure) is a distance
function setting.
The distance protection parameter ‘t1EvolFaults’ enables the
time to be set during which a subsequent fault (evolving or unsuccessful reclosure) results in a three-phase trip, i.e. every
second trip by the distance protection function trips all three
phases. The auto-reclosure function also signals the switchover
to three-phase tripping by exciting the signal ‘Trip 3-Pol’ at the
end of the fault discrimination time ‘t Discrim. 1P’.
It is advisable to set the time ‘t1EvolFaults’ longer than the autoreclosure dead time ‘t Dead1 1P’.
't Timeout'
The parameter ‘t Timeout’ determines the period after the dead
time within which the close signal must be issued, otherwise a
‘Def.Trip’ is generated and no further reclosure attempt is made.
Before a close command is issued at the end of every dead time,
the logic [(‘synchroChck’ AND ‘CO ready’) OR ‘Dead Line’ OR
‘ExtSCBypas’)] is checked and the command only enabled providing all the criteria are correct within the setting of ‘t Timeout’.Should a ‘CondBlkAR’ signal occur during a reclosure cycle (i.e.
the ‘AR in prog.’ signal is active), it only becomes effective from
the end of the current reclosure cycle and providing it is still active.
A reclosure cycle remains blocked for the duration of the set
blocking time ‘t AR Block’ after the last binary I/P has been enabled. Blocking also takes place during initialisation of the protection relay when its auxiliary supply is switched on or the parameter settings are being loaded.In order to control the auto-reclosure function, it is necessary to
configure the three I/P signals ‘Trip CB’ (general trip), ‘Trip CB 3P’
(three-phase trip) and ‘Start’. The normal procedure to achieve this
is to select the protection signals via the sub-menu ‘OUTPUT
FROM FUNCTION’. Since the auto-reclosure function is completely independent, signals from other functions may also be
selected.
