How to Synchronize Generators on a Ship?

Synchronization of Generators is the process of matching parameters such as voltage, frequency, phase angle, phase sequence, and waveform of an alternator (generator) or other sources with a healthy or working power system. A generator cannot supply electricity to an electric power system unless its voltage, frequency, and other parameters are precisely matched to the network. The exciter current and the generator’s engine speed are controlled to achieve synchronization.

 Synchronization is primarily needed when two or more alternators work together to supply power to the load. Electrical loads are very inconsistent and they vary with time (depending on the load) and so it is necessary to interconnect the alternators
