| Traditional fossil energy power generation has serious environmental pollution.At the same time,our country continues to develop clean energy power generation.In the future,wind power will gradually develop from centralized type to distributed type.Horizontal axis wind turbines are not suitable for distributed layout while the vertical axis wind turbines meet the requirements of distributed new energy power generation technology due to the small size,low cost,and simple control.The switched reluctance generator maintains the simple structure and reliable operation,which is suitable for the field of distributed wind power generation with obvious cost advantages.Under this background,this work proposes a scheme of switched reluctance vertical axis wind power generator,which can be used for distributed wind power generation or household heating in northern winter.In this work,a 10 kW switched reluctance vertical axis wind turbine was designed,and the overall structural stability of the wind turbine was verified.And the switched reluctance generator was optimized and designed based on the particle swarm algorithm.Based on the related researches on vertical axis wind turbines and switched reluctance generators domestic and overseas,this work completed the structural design of vertical axis wind turbines according to the aerodynamic theory and the design theory of switched reluctance generator.The simulation modeling was completed using ANSYS Workbench,and the structural statics and dynamics modal analysis of the wind turbine during operation were completed according to the actual load calculation.Besides,the rationality of the design parameters was discussed and verified in this work,and the design and modeling of the wind turbine body structure was completed.According to design requirements and electromagnetic theory,the design of switched reluctance generator was completed.Using ANSYS Maxwell,finite element modeling and simulation.In this work,a response surface model for the optimization objective of the switched reluctance generator was established in Design-Expert,and the fitting accuracy analysis of the model was completed.Based on the particle swarm algorithm,the multi-objective parameters including output torque and power density were optimized in order to improve the performance of the generator.In summary,this work analyzes the operating conditions of the vertical axis switched reluctance wind turbine,completes the design and optimization,and provides a theoretical reference for the subsequent in-depth study of the vertical axis switched reluctance wind turbine. |
