ABB SYNCHROTACT ® 5 Synchronizing and Paralleling Equipment
SYNCHROTACT® 5 is the fifth generation of synchronizing equipment produced by
ABB Switzerland Ltd in Switzerland. SYNCHROTACT products from ABB are used for
automatic synchronization of generators with power lines and for paralleling of
synchronous lines. They are designed for fully automatic operation by dual-channel
or single-channel systems.
Synchronizing equipment are used in power
stations where a generator needs to be
paralleled with a power line or in substations
to parallel two synchronous lines.
Power circuit breakers can only be closed if
voltage at both ends is synchronous. If it is
not, it will cause a disturbance in the power
network, trip the breaker, shock the generator and unit transformer. In extreme cases, it
can damage both.
SYNCHROTACT 5 guarantees a safe and
reliable synchronization whether as a monitoring element for manual paralleling or as
an independent fully-automatic synchronizing
unit.
SYNCHROTACT 5 covers the following areas
of application:
Automatic synchronization and paralleling
of generators with power lines
(see Fig. 1 below),
2. Automatic paralleling for synchronous
and asynchronous lines and busbars
(see Fig. 2 below),
3. Monitoring (Synchrocheck) of automatic
or manual paralleling of power lines,
generators and voltage-free lines (dead
bus), see Fig. 3 below.
