Synchronising Two Generators Connected In Parallel

Synchronising two generators that are connected in parallel is important to do correctly, to avoid potential damage.

A two generator system is found on ships for example, as SOLAS regulations require more than one marine generator on-board.

Lets first consider the generator that is already connected to the ship, or a land-based electrical system.

This generator is producing a three-phase voltage output typically of 440 Volts for a marine ships installation or 400 / 415 volts for a land-based (shore side) generator system. An example of a land-based installation application is powering a hospital emergency power backup system.

Being a three-phase generator means that three voltage sine wave outputs are produced.

Each of the three voltage outputs is sine waves because the generator produces Alternating Current (AC)
