Effect of best position blade pitching on power coefficient of VAWT at different tip speed ratio by SST & DMST model [PDF]

FME Transactions, 2018
This paper analyses the effect of best position blade pitching on the power coefficient of vertical axis wind turbine (VAWT) at different tip speed ratios (TSRs). Single Stream Tube (SST) and Double Multiple Stream Tube (DMST) models are used for present

Optimal Control to Increase Energy Production of Wind Farm Considering Wake Effect and Lifetime Estimation

Applied Sciences, 2017
In a wind farm, the upstream wind turbine may cause power loss to the downstream wind turbines due to the wake effect. Meanwhile, the energy production is determined by the power generation and the lifetime of the wind turbine.

DESIGNING PITCH CURVES OF NON-CIRCULAR GEARS

Scientific Journal of Silesian University of Technology. Series Transport, 2018
The paper examines the design and generation of gear drives with non-circular gears. Gearings with a changing transmission gear ratio are used for the purposes of practical experimentation, even though “standard” gearings with a constant transmission gear ratio are used more often.
