Technoeconomic analysis of electricity generation from wind energy in Kutahya, Turkey

Arslan, Oguz - In: Energy 35 (2010) 1, pp. 120-131

Conventional energy usage has various environmental effects that cause global warming. Renewable energy sources are thus more favorable because they have nearly zero emission. Wind energy, among the various renewable sources, finds increasing usage, concurrent with developing technology. In...

Assessment of optimum tip speed ratio in wind turbines using artificial neural networks

Yurdusev, M.A.; Ata, R.; Çetin, N.S. - In: Energy 31 (2006) 12, pp. 2153-2161

Wind turbine blade design depends on several factors, such as turbine profile used, blade number, power factor, and tip speed ratio. The key to designing a wind turbine is to assess the optimal tip speed ratio (TSR). This will directly affect the power generated and, in turn, the effectiveness...

Comparative analysis on power curve models of wind turbine generator in estimating capacity factor

Chang, Tian-Pau; Liu, Feng-Jiao; Ko, Hong-Hsi; Cheng, … - In: Energy 73 (2014) C, pp. 88-95

The capacity factor is an essential indicator in evaluating a wind turbine's efficiency. In this paper, four kinds of power curve models—linear, quadratic, cubic, and general—are applied to estimate the capacity factor of a pitch-controlled wind turbine based on the Weibull probability...
