Non-Linear Global Sizing of High Speed PM Synchronous Generator for Renewable Energy Applications

This paper presents a step by step sizing procedure of High Speed Permanent Magnet Synchronous Generators (HSPMSGs) for renewable energy applications to be driven by micro-turbines. The final design offers significant reductions in both weight and volume in a power range of 5:500 kW. A rotor length to diameter ratio is used as an important design parameter. The results are depicted by 3D plot figures for a number of machines sizing. The simulation of generators sizing is performed using MATLAB. Then, the paper proposes genetic optimized sizing of High Speed Permanent Magnet Synchronous Generators. These designs have more significant improvement in weights and volumes than usual or classical. Efficiency Maximizer Genetic Sizing is proposed. Finally, Optimum Torque per Ampere Genetic Sizing is predicted. The optimization variables are the same in every optimization process. The genetic results are well depicted by some variables 3D figures for initial and detailed sizing. The simulation of generators sizing is performed using MATLAB, and Genetic Algorithm.
