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

An Investigation on Performance of Shrouding a Small Wind Turbine with a Simple Ring in a Wind Tunnel
Ducted wind turbines are a kind of small wind turbine having a diffuser or any other shape around the rotor which increases the air flow through the blades and absorbs more power. In the present study, a small wind turbine was ducted with a relatively simple ring and its performance was investigated in a wind tunnel. The duct is shaped using rolling steel sheets on a sloping surface and finally...
متن کاملComprehensive Parametric Study for Design Improvement of a Low-Speed AFPMSG for Small Scale Wind-Turbines
In this paper, a comprehensive parametric analysis for an axial-flux permanent magnet synchronous generator (AFPMSG), designed to operate in a small-scale wind-power applications, is presented, and the condition for maximum efficiency, minimum weight and minimum cost is deduced. Then a Computer-Aided Design (CAD) procedure based on the results of parametric study is proposed. Matching between t...
