O que (quem) é synchronous generator - definição

PROCESS OF MATCHING THE SPEED AND FREQUENCY OF A GENERATOR OR OTHER SOURCE TO A RUNNING ALTERNATING CURRENT POWER NETWORK
Alternator synchronization; Isochronous frequency; Sochronous frequency; Synchronous generator
  •  From top to bottom: [[synchroscope]], voltmeter, frequency meter. When the two systems are synchronized, the pointer on the synchrosope is stationary and points straight up.

Synchronization (alternating current)         
In an alternating current electric power system, synchronization is the process of matching the 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.

  • The [[Faraday disk]] was the first electric generator. The horseshoe-shaped magnet ''(A)'' created a magnetic field through the disk ''(D)''. When the disk was turned, this induced an electric current radially outward from the center toward the rim. The current flowed out through the sliding spring contact ''m'', through the external circuit, and back into the center of the disk through the axle.

A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft mounted permanent magnet mechanism and current is induced into the stationary armature.

Synchronization (alternating current)

In an alternating current (AC) electric power system, synchronization is the process of matching the frequency and phase and voltage of a generator or other source to an electrical grid in order to transfer power. If two unconnected segments of a grid are to be connected to each other, they cannot safely exchange AC power until they are synchronized.

A direct current (DC) generator can be connected to a power network simply by adjusting its open-circuit terminal voltage to match the network's voltage, by either adjusting its speed or its field excitation. The exact engine speed is not critical. However, an AC generator must additionally match its timing (frequency and phase) to the network voltage, which requires both speed and excitation to be systematically controlled for synchronization. This extra complexity was one of the arguments against AC operation during the war of currents in the 1880s. In modern grids, synchronization of generators is carried out by automatic systems.
