ABB offers synchronous wind turbine generators. These generators incorporate the permanent magnet technology and have been designed for medium speed, high speed and direct drive applications. Synchronous wind generators generate output power ranging from 500 kilovolt amperes to 5,000 kilovolt amperes. The number of poles in these generators varies in between 4 and 60 or even more than 60. Synchronous wind generators operate at a maximum voltage ranging from 400 volts to 4,000 volts. The operating speed of the synchronous wind turbine generator ranges from 0 rotations per minute to 2,000 rotations per minute.
The synchronous wind turbine generator is available in three different versions including low speed permanent magnet generators, medium speed and high speed permanent magnet generators. The low speed permanent magnet generator from ABB has a simple and robust design that requires minimal maintenance. This gearless efficient system incorporates a low speed rotor and is devoid of a separate cooling or excitation system. The absence of a separate excitation or cooling system results in low life cycle costs, minimum wear and increased durability.
The components of the low speed permanent magnet generator are accessible, thereby facilitating easy installation. This synchronous wind generator from ABB can be attached directly with the turbine that results in the formation of a structurally integrated unit.
