Design and realisation of a high-performance active pitch-controlled H-Darrieus VAWT for urban installations

This paper reports the design of a 3×3m (diameter/height) pitch-controlled lift based H-Darrieus VAWT for urban installations. Among others, this type of wind-turbine was chosen for the potential feature modifications with respect to the classical fixed-pitch concept, such as self-starting mode for standalone applications and active pitch control efficiency. Preliminary results in terms of design optimization are presented.
