Which of the following describes a synchronous generator?

A synchronous generator is designed to operate in harmony with the electrical grid, which is why it is categorized as a synchronous machine. These generators are built to maintain a constant rotational speed that matches the grid frequency, typically 60 Hz in North America or 50 Hz in many other parts of the world. This synchronization ensures that the power generated is delivered consistently to the grid, avoiding phase discrepancies that could disrupt the stability and reliability of the electrical system.

The ability of a synchronous generator to maintain a constant frequency is crucial for the operation of power systems since it allows multiple generators to work together without causing instability. In contrast, other types of generators, such as asynchronous or induction generators, may operate independently or may require additional systems to synchronize with the grid.

By generating power that is in sync with the grid frequency, synchronous generators provide a stable and reliable source of electricity, making them essential components in power generation and distribution.
