Auto-Reclosing (Modified 96-12) - ABB SPAC 531 C User Manual And Technical Description

Auto-reclosing
(modified 96-12)
The control module SPTO 6D3 features an
auto-reclose unit for five auto-reclose cycles.
The unit obtains its start initiation signals from
the protection relay modules. The start initia-
tion signals are named AR1, AR2 and AR3.
The signals AR1, AR2 and AR3 are generated by
the starting or tripping signals of the protection
relay modules. The detailed function of the
signals and their configuration are described in
the general description of the feeder terminal, in
chapter "Intermodular control signal exchange".
Under the control of these signals the auto-
reclose unit of the control module executes the
required auto-reclose shots.
If the starting signals of the protection relay
modules are used to initiate the auto-reclosing
the control module opens the breaker after a
preset time, the so called starting time. If the
tripping signals of the protection relay modules
are used to initiate auto-reclosing, the con-
cerned protection relay module opens the
breaker. In both cases the control module closes
the circuit breaker after the preset dead time (see
Fig. 17).
If required, external start initiation of auto-
reclosing can be achieved via input channel 14.
This input can be logically connected to one of
the three initiation signals, AR1, AR2 or AR3.
Setting parameter S1 is used for selecting the
signal.

Each auto-reclose cycle has the following pa-
rameters, x = the number of the cycle + 1:
Sx1 Defines if the auto-reclose cycle is to be
started or inhibited when signal AR1 is
activated
Sx2 Defines if the auto-reclose cycle is to be
started or not started when signal AR2 is
activated
Sx3 Defines if the auto-reclose cycle is to be
started or not started when signal AR3 is
activated
Sx4 Defines the time (starting time) after which
the control module opens the circuit
breaker when signal AR2 is activated. Set-
ting range 0.00...5.00 s in 0.1 s steps. If a
tripping signal is used to initiate the auto-
reclose cycle the starting time should be
0.00
Sx5 Defines the time (starting time) after which
the control module opens the circuit
breaker when signal AR3 is activated. Set-
ting range 0.00...5.00 s in 0.1 s steps. If a
tripping signal is used to initiate the auto-
reclose cycle the starting time should be
0.00
Sx6 Defines the dead time of the auto-reclose
cycle. Setting range 0.2...300.0 s in steps
of 0.1 s.
