Generator synchronization is the process of matching parameters such as voltage, frequency, phase angle, phase sequence, and waveform of diesel generator or other source with a healthy or running power system. This is done before the generator is reconnected to the power system. Once a generator is synchronized with the parameters of another generator, alternator, or bus bar, the system can run smoothly again. With multi-generator synchronization systems, users avoid high costs and dependency on single generator.

in Actic Engineering; the   Automatic Synchronization System is adopting the PLC(programmable logic controller) of the DSE 8610 Intelligent Parallel Generating Set made by UK Deep Sea Electronics plc. The DSE 8610 series module has been specially designed to allow the operator to start and stop the generator, and if required, transfer the load to the generator either manually(via fascia mounted push-button) or automatically.
