Introduction to Wind Turbine Technology

“…It has been found by the authors that the last, simple method is accurate enough for preliminary assessments, as required in this publication. The power of a wind stream P wind according to Wood (2011) and Shamshirband et al (2014) is given by:…”

Numerical Investigation of a Novel Type of Rotor Working in a Palisade Configuration

“…In addition to large HAWTs farms, wind energy technology is also a viable energy production alternative for households and suburban applications [12]. Usually due to HAWTs immense sizes, noise generation, aesthetic and safety concerns, these wind turbines are typically out of scope in the urbanized environment and for the private sector prosumers [13,14]. This is where small VAWTs are gaining popularity [15].…”

“…Based on the principle of operation, typical VAWT solutions are either drag-driven, lift-driven, or a combination of both. Two most popular of VAWTs are Darrieus and Savonius turbines [4,9,10,13,16,17]. The towers of VAWTs are structurally simpler and both generators with gearboxes may be positioned close to the ground level, which means that maintenance is also easier.…”

“…Additionally, it cannot harness higher wind velocities due to installation on shorter towers. Similar to HAWTs, Savonius turbines need more materials per unit power rating [10,13]. Moreover, most VAWTs are not considered self-starting, except the designs like Savonius rotors, which are solely drag-driven.…”
