Which of the following is a key function of a synchronous generator?

• A. It can adjust power output based on demand
• B. It operates independently of other power sources
• C. It maintains a consistent speed with grid frequency
• D. It primarily produces renewable energy

Answer: (C)

The key function of a synchronous generator is to maintain a consistent speed that is in sync with the frequency of the electrical grid. This is crucial for ensuring that the electricity generated matches the needs of the grid in real-time. Synchronous generators achieve this by having a rotor that rotates at a speed directly related to the frequency of the alternating current being produced. For instance, in many power systems operating at 60 Hz, a synchronous generator would rotate at a speed of 1800 RPM for a two-pole machine. This synchronization helps to stabilize the frequency of the grid and allows for reliable and consistent power delivery. The ability to maintain this speed helps ensure that the generator operates efficiently and can contribute to the overall stability of the electrical system, which is essential when there are varying demands for electricity. This makes synchronous generators a vital component in power generation within electrical grids.
