摘要:风能是太阳能的一种转换形式,是一种重要的自然能源。风能作为一种无污染、可再生的绿色能源,它对于解决全球性的能源危机和环境危机有着重要的意义。因此,风力发电成为各国学者研究的重点。目前,国内学者对大型风力发电的研究已日趋成熟,但对于实验室风力发电机的研制还是比较欠缺的。
本次毕业设计的重点是利用HSW-A-01风力发电测试平台实验进行实验,该设备能让学生直观的了解风力发电的原理,以及大致测算出影响风力发电的各个因素,方便风力发电的实验,同时在制作和测试过程中对出现的一些现象进行深刻的思考,具有很强的实用性和趣性。在实验的过程中,对风能的转化功率,风速等影响发电的因素,进行测量,并与理论进行对比,进而对影响风力发电效率的因素进行分析。8636

Basic Performance Testing and Analysis of Small-scale Wind Power Generation System
Abstract: Wind energy is the form of a conversion of solar energy is an important natural energy. Wind energy as a non-polluting, renewable green energy, it is of great significance in solving the global energy and environmental crises. Therefore, wind power has become the focus of the study of scholars from various countries. At present, domestic scholars on the study of large-scale wind power has become increasingly mature, but for the development of laboratory wind turbine is still lacking.
The focus of this graduation project is intended to use the HSW-A-01 experiment instrument of wind power, the device allows students to easily understand the principle of wind power, as well as roughly estimated that the various factors affecting wind power, to facilitate future wind power experiment teaching, while in the production the phenomenon of the emergence of some deep thinking and testing process, and has a strong practical and interesting. In the development of the process, while the conversion of wind energy power, wind speed and other factors that affect the generation, measurement, and compared with theory, and then come the factors affecting the efficiency.
Key words: wind power generation;HSW-A-01 experiment instrument of wind power; conversion of wind energy power
