Abstract

Abstract This paper describes the development, design and function of a test rig for the measurement of small wind turbines in a wind tunnel and presents the first exemplary measurements of the performance characteristics of various horizontal and vertical rotors. A central part of this test rig is the developed control system with an electronic load, which enables an automated recording of the measured values for the evaluation of the power coefficients (cp) and tip-speed ratio (λ) values. Another challenge emerges owing to the known differences in the power spectrum, because the power coefficients of drag rotors (<20%) are different from those of buoyancy rotors (<40%). The system was adapted to the different ranges by means of a stepless switching using various resistors. The entire control and regulation unit was compactly implemented using a programmable logic controller (PLC) and dynamically linked to the operating parameters of the wind tunnel. This enables an automated operation of the wind tunnel during the determination of the performance parameters of the investigated wind turbines.

小型风力机风洞测量试验台的研制

摘要本文介绍了小型风力机风洞测试试验台的研制、设计和功能，并首次进行了各种水平和垂直转子性能特性的示例性测试。该试验台的核心部分是开发的带有电子负载的控制系统，该系统可以自动记录测量值，以评估功率系数(cp)和叶尖速比(λ)值。由于已知功率谱的差异，另一个挑战出现了，因为阻力转子的功率系数(<20%)不同于浮力转子的功率系数(<40%)。该系统通过使用各种电阻的无级开关来适应不同的范围。整个控制和调节单元使用可编程逻辑控制器(PLC)紧凑地实现，并动态链接到风洞的运行参数。这使得风洞在确定所研究的风力涡轮机的性能参数期间能够自动操作。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
