Optimal design of the generator of microturbine using genetic algorithm and PSO
Microturbine is one of the distributed power generation that produced electric in the remote and disastrous zones where grid power is unavailable. The design of its high-speed generator is much difficult and quite different from a conventional generator with low speed, because of high rotor speed and high frequency of the stator winding current. In this paper, the optimal design of this high speed axial flux generator (HSAFG) is introduced. The genetic algorithm and particle swarm optimization (PSO) are used for optimizing the efficiency of machine. PSO can show the better efficiency. At last, the influence of ratio of inner diameter to outer diameter (lambda) is discussed. The optimal lambda is between 0.3 and 0.5.
