ABB Introduces New Slip-Ring Generators
ABB has introduced a new standard series of slip-ring generators designed to fit doubly fed wind turbines. The new generators cover the power range of 1.5 MW to 2 MW.
The standard base construction for different powers enables large-scale manufacturing, and the modular turbine interface connections can be changed to suit individual customers’ specifications, according to the company. Both air and water cooling are available, as is a 60 Hz version for North American installations.
Features of the new generator series include a patented rotor design with an optimized winding-end support ring.
An improved insulation level offers high-voltage peak integrity and allows the use of various types of converters, ABB says. The new design also incorporates minimized total harmonic distortion levels.
