Construction of Alternator | Electrical4U

In most practical construction of alternator, it is installed with a stationary armature winding and a rotating field unlike in the case of DC generator where the arrangement is exactly opposite. This modification is made to cope with the very high power of the order of few 100 Megawatts produced in an AC generator contrary to that of a DC generator.

AC SYNCHRONOUS GENERATORS - USNA

drives the synchronous generator is a gas turbine (Allison 501-34K). The gas turbine converts the F76 fuel into mechanical power. A governor connected to the prime mover regulates its speed and controls the amount of mechanical power transmitted to the generator. The generator in turn converts the mechanical power to electrical power.

Synchronization (alternating current) - Wikipedia

In an alternating current electric power system, synchronization is the process of matching the speed and frequency of a generator or other source to a running network. An AC generator cannot deliver power to an electrical grid unless it is running at the same frequency as the network. If two segments of a grid are disconnected, they cannot exchange AC power again until they are brought back .
