What are synchronous generators?
Synchronous generators are devices that convert mechanical energy into electrical energy by maintaining a constant rotation speed and synchronized with the frequency of the electrical energy they produce. They operate by using a rotating magnetic field, created by a DC-powered rotor, to induce alternating current (AC) in the stator windings.
This synchronization ensures that the generator produces a constant and stable frequency of electrical energy.
A synchronous generator works by causing its rotor, powered by direct current (DC), to generate a magnetic field. As the rotor turns, it creates a rotating magnetic field that interacts with the stator windings, inducing alternating current (AC).
The rotor speed is precisely controlled to match the grid frequency, which keeps the generated AC current synchronized with the power system frequency.
How does a synchronous generator work?
For a backup generator, “synchronous” means that the output frequency of the generator is precisely aligned with the frequency of the power grid or other electrical systems to which it is connected.
This ensures that the backup generator provides stable and reliable power during outages, maintaining a constant frequency and voltage to match the connected loads.
What does synchronous mean for emergency generator?
An inverter is not a synchronous generator. While a synchronous generator produces electrical energy through mechanical rotation and maintains synchronization with the grid frequency, an inverter is an electronic device that converts direct current (DC) to alternating current (AC).
An inverter does not generate electricity but changes the shape of the existing power supply.
The main difference between synchronous and asynchronous generators is how they operate and are synchronized with the grid. A synchronous generator operates at a constant speed synchronized with the grid frequency, ensuring a stable output frequency. In contrast, an asynchronous generator, also called an induction generator, operates at a variable speed and adjusts its output based on system conditions.
Asynchronous generators do not maintain precise synchronization with the grid frequency, but are more robust and simpler in design.
