ATS Synchronization approach is implemented in this project. An automatic transfer switch
(ATS) is an electrical switch that switches a load between two sources. It is often installed with a
backup generator, so as to provide temporary electrical power in case of mains electrical power
failure. Synchronization modules will be used for the synchronization purposes. The purpose is
to obtain a reliable Power System in which seamless transition between two sources is obtained
to ensure continuous electrical supply to avoid blackouts. ATS Synchronization function
involved in this project includes steps like A short while before normal power source fails; the
genset is synchronized with the main power supply. When the main power source fails the
transfer switch breaks its connection to the mains and shifts the electrical load to the emergency
power source. When utility power is restored, the transfer switch returns the load from the
generator to the normal one. GC400 mains is the perfect solution for the management of a genset
working in parallel to the mains by the internal power regulator. Soft loading and unloading is
automatically performed. GC400 mains a powerful genset controller designed for synchro/
parallel applications. Based on the load demand, the controller is able to start or stop the genset.
All ATS synchronization systems include load sharing function to ensure balanced use of the
di?erent gensets. Load sharing function is available as option: when energy demand is low, only
on genset starts the other remain in standby unless the demand increases. According to load
demand the utility grid and genset are synchronized through module and hence uninterrupted
supply is available to the load.
