Performance Evaluation of a Stator Modular Ring Generator for a Shrouded Wind Turbine

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...

Design and performance of a cm-scale shrouded wind turbine for energy harvesting

A miniature shrouded wind turbine aimed at energy harvesting for power delivery to wireless sensors in pipes and ducts is presented. The device has a rotor diameter of 2 cm, with an outer diameter of 3.2 cm, and generates electrical power by means of an axial flux permanent magnet machine built into the shroud. Fabrication was accomplished using a combination of traditional machining, rapid pro...

Fault-tolerant Control of a Wind Turbine with Generator Stator Inter-turn Faults

Faults of wind turbine generator electromechanical parts are common and very expensive. This paper introduces a generator fault-tolerant control scheme for variable-speed variable-pitch wind turbines that can be applied regardless to the AC generator used. The focus is on generator stator isolation inter-turn fault that can be diagnosed and characterised before triggering the safety device. An ...
