An asynchronous generator is a type of electrical generator that operates without being synchronized to the grid frequency. It typically uses an induction machine, which generates electricity when driven by a prime mover, such as a wind turbine or a water turbine. The generator produces power by converting mechanical energy into electrical energy, allowing it to function independently of the electrical grid. These generators are commonly used in renewable energy applications, particularly in wind energy systems. They can operate efficiently at varying speeds, making them suitable for fluctuating energy sources. Asynchronous generators are valued for their simplicity and reliability in generating electricity.
