Application of particle swarm optimization in the design of large permanent magnet synchronous generators for wind turbines

This paper presents the use of particle swarm optimization (PSO) in the design of direct-drive permanent magnet synchronous generators (PMSGs) for mega-watt (MW) level wind turbines. The generator design requirements and constraints are outlined and the PSO is described along with the variations that can be applied depending on the design priorities. Optimization results are presented and compared to designs reported in the technical literature. Results show that the proposed optimization technique is easy to create and apply and produced competitive designs to those using other methods.
