MACHINE-TRANSFORMER UNITS FOR WIND TURBINES
Electrical Engineering & Electromechanics, 2016 Background. Electric generators of wind turbines must meet the following requirements: they must be multi-pole; to have a minimum size and weight; to be non-contact, but controlled; to ensure the maximum possible output voltage when working on the power supply system. Multipole and contactless are relatively simply realized in the synchronous generator
