The new generators cover the power range 1.5 to 2.0 MW. Their modular and adaptable interface connections ensure easy integration into the different DF turbines in use today. They are also an excellent choice as replacement units at existing wind parks.

The standard base construction for different powers enables high quality large-scale manufacturing for fast delivery times, and the modular turbine interface connections can be changed to suit the individual customer’s specifications. Both air or water cooling are available, and a 60 Hz version is supplied to customers in the US markets.

Features of the new generator series include a patented rotor design with an optimized winding-end support ring to deliver enhanced overspeed withstand and high cooling performance. The improved insulation level offers high voltage peak integrity and allows the use of various types of converter. The new design also offers minimized Total Harmonic  Distortion (THD) levels.

The reliable ABB slip ring design used in the new generator series is based on more than half a century of experience in building slip ring motors for many demanding applications. This in-house expertise is combined with specialized know-how provided by leading slip ring manufacturers. The optimized cooling air circulation of the slip ring unit offers reliable operation even during peak loads. The new rotor construction with the ABB slip ring unit enables continuous reactive power production and high stability during sudden overspeeds

ABB has established a strong reputation as a reliable supplier to the wind power sector. It is known for its proven generator – converter packages, as well as delivering a wide range of electrical components for wind power systems. Over the last 30 years ABB has supplied around 30 000 generators for wind turbines, and it is also one of the leading suppliers for the mainstream doubly-fed concept. The new generator series from ABB is based on more than 100 years of experience in manufacturing all types of demanding motor and generator designs.
