A 1 MVA High-Temperature Superconducting Generator for Windmills
Work is underway at the leading foreign and Russian scientific centers on developing windmills employing the superconductivity effect. Generators constructed on the basis of high-temperature superconducting (HTSC) materials feature high specific power capacity and efficiency; they are more compact and have an increased service life. In addition, the use of a wind generator equipped with a wave multiplier makes it possible to obtain a higher generator rotation frequency and achieve a lighter weight of the windmill rotary part. The article presents the results from theoretical calculation and numerical simulation together with description of the design and results from testing Russia’s first 1 MVA superconducting synchronous generator with the field winding made using a second-generation HTSC tape for windmills.
