【摘要】：随着全球传统常规能源的日益匮乏,风能作为清洁能源,其具有储量大、可循环利用、没有污染等优势,而得到了人们的普遍关注。在此背景下,本论文以偏心式S型风机发电机为研究对象,运用了数值模拟分析、装置电路设计、实验研究相结合的方法,对偏心式S型风力机进行了系统的研究。首先利用RNGk-ε模型和滑移网格技术把风机叶轮在各迎角下进行了非定常分析,从不同的重叠比和不同的叶片数两个方面对风轮进行仿真,然后通过比较分析得到最佳参数,为接下来的风机设计提供理论数据。其次通过CAD软件设计出一种偏心式多功率风力发电机,然后对其主要结构进行优化和校核,再通过与其他垂直轴风力发电机的比较,分析偏心式多功率发电机自身的优势与不足,从而为以后此类风机的研究打下理论基础。最后介绍、分析了小型风力发电机的各个部分的设计原则,并给出了详细的电路结构图和计算。本系统STC12C5A60S2单片机为核心,设计出了偏心式S风力发电机控制系统的检测电路和驱动电路等硬件电路,给出了控制系统软件的主程序、子程序及终端服务程序的流程图,并对实验结果和仿真结果进行了比较分析。本论文基于垂直轴风机的研究下,对偏心式S型风力发电机做了系统的研究,得出一套系统的理论研究数据,从而为以后偏心式S型风机的研究提供参考。
[Abstract]:With the increasing shortage of traditional conventional energy, wind energy, as a clean energy, has the advantages of large reserves, recycling, no pollution and so on, and has been paid more and more attention. In this background, the eccentric S-type wind turbine is studied systematically by the methods of numerical simulation, circuit design and experiment. The unsteady analysis of fan impeller at different angles of attack is carried out by using RNGk- 蔚 model and slip grid technique. The wind turbine is simulated from two aspects: different overlap ratio and different blade number, and then the best parameters are obtained by comparison and analysis. Provide theoretical data for the following fan design. Secondly, an eccentric multi-power wind turbine is designed by CAD software, and its main structure is optimized and checked, and then compared with other vertical axis wind turbines. The advantages and disadvantages of eccentric multi-power generator are analyzed, which will lay a theoretical foundation for the study of this kind of fan in the future. Finally, the design principle of each part of small wind turbine is analyzed, and the detailed circuit structure diagram and calculation are given. The hardware circuit of the eccentric S wind turbine control system is designed, such as detecting circuit and driving circuit. The main program, subroutine and terminal service program flow chart of the control system software are given. The experimental results and simulation results are compared and analyzed. Based on the research of vertical axis fan, this paper makes a systematic study on eccentric S-type wind turbine, and obtains a set of theoretical research data, thus providing a reference for the research of eccentric S-type wind turbine in the future.
