Marine electrical power station during regular operation to perform the synchronization between the generators and share the active load when they work in parallel. The synchronization of generators required parameters of voltage, frequency, voltage phase angle between the generator and the bus be within the permissible range and the problem of timing synchronization is extremely. It is important that choosing the incorrect timing of synchronization can lead to a power outage of the entire ship, causing a dangerous situation for people, cargo, equipment and the ship. Currently, the synchronous and active load division equipment is being applied with similar techniques, leading to the large error in determining the timing of synchronization, causing the synchronization process to cause large current pulses, synchronization may not be successful and the active power difference between generators is large. Therefore, the problem of designing the system to automatically synchronize and divide the load of digital applications will reduce errors, increase the accuracy and reliability of the system.
