This paper targets to the challenge of electrical energy production and energy efficiency by studying synchronous reluctance machines (SynRM), as an alternative to permanent magnet generator in electric power generation with focus in renewable energy applications. Considering the SynRM as a special case of the wound-rotor synchronous generator, this paper explores the operating limits of the machine...
Modular multilevel converter (MMC) is a recently emerged multilevel topology for high-voltage high-power applications. However, in wind power application the performance of the MMC has not been deeply investigated. In this paper the application of MMC in wind energy systems is studied. The converters used to connect the wind turbine to the grid having the rated active powers of 2MW and 10MW are designed...
The use of permanent magnets offers freedom in machine design and the highest possible efficiencies for wind power machines. Although full power converters must be used with permanent magnet machines, these converters make it possible to fulfill even the strictest grid codes. If appropriate care is taken in selecting the exact magnetic material composition, Neodymium-Iron-Boron magnets are compatible...
