Analyzing on structure parameters for low-speed permanent magnet synchronous generator

Renewable energy sources, especially wind turbine generators, are considered as important generation alternatives in electric power systems due to their no exhausted nature and benign environmental effects. Compared to conventional synchronous generator, permanent magnet synchronous generator has many outstanding performances. Due to the technical and economical advantages, low-speed permanent magnet synchronous generators are becoming more attractive for wind power generation. They are directly drived by the wind, and economize the gear as an additional mechanical component. The low-speed permanent magnet wind power generator is introduced in this paper, and parameter analyzing is made to deduce the inherent relationship between the structure parameters and the performance, which is the fundament of parameter optimization.
