摘要：

The problem of low productivity and low output stability of permanent magnet wind power system was aimed at in this research. The loss of heat and heat transfer performance was considered, and the wind turbine was regarded as an isolated system. Entropy entropy production model was established. The dynamic process of thermal power generation and diffusion entropy generation was analyzed. The loss, the heat transfer characteristics, the three field coupling mechanism and the entropy production rate distribution law were studied. Finally, the minimum entropy production rate was taking as the target. The optimal operating conditions and the magnetic thermal structure of the unit were determined by adjusting the key factors, such as the incoming wind speed, the yaw angle of the unit, gap structure and air gap length between stator and rotor and so on. The minimum entropy production rate optimization scheme of the wind turbine was proposed. © 2018, Electrical Technology Press Co. Ltd. All right reserved.
