Insect fatalities at wind turbines as biodiversity sinks

open access: yesConservation Science and Practice, 2021
Evidence is accumulating that insects are frequently killed by operating wind turbines, yet it is poorly understood if these fatalities cause population declines and changes in assemblage structures on various spatial scales. Current observations suggest

The Long-Term Impact of Wind Power Generation on a Local Community: Economics Analysis of Subjective Well-Being Data in Chōshi City

open access: yesEnergies, 2021
In this study, we analyzed the external effects of wind turbines, which are often considered detrimental to the promotion of wind power generation. Understanding these externalities is essential to reaching a consensus with residents who live near the ...

Extracting Feature Information and its Visualization Based on the Characteristic Defect Octave Frequencies in a Rolling Element Bearing

open access: yesData Science Journal, 2007
Monitoring the condition of rolling element bearings and defect diagnosis has received considerable attention for many years because the majority of problems in rotating machines are caused by defective bearings.

Techno-economic comparison of operational aspects for direct drive and gearbox-driven wind turbines [PDF]

open access: yes, 2010
The majority of wind turbines currently in operation have the conventional Danish concept design-that is, the three-bladed rotor of such turbines is indirectly coupled with an electrical generator via a gearbox.

Optimization of periodic maintenance for wind turbines based on stochastic degradation model [PDF]

open access: yesArchives of Electrical Engineering, 2021
The degradation process of wind turbines is greatly affected by external factors. Wind turbine maintenance costs are high. The regular maintenance of wind turbines can easily lead to over and insufficient maintenance.

Wind Turbines and Human Health [PDF]

open access: yesFrontiers in Public Health, 2014
The association between wind turbines and health effects is highly debated. Some argue that reported health effects are related to wind turbine operation [electromagnetic fields (EMF), shadow flicker, audible noise, low-frequency noise, infrasound]. Others suggest that when turbines are sited correctly, effects are more likely attributable to a number ...

Wind direction estimation using SCADA data with consensus-based optimization [PDF]

open access: yesWind Energy Science, 2019
Wind turbines in a wind farm typically operate individually to maximize their own performance and do not take into account information from nearby turbines.

Modelling the aerodynamics of vertical-axis wind turbines in unsteady wind conditions [PDF]

open access: yes, 2013
Most numerical and experimental studies of the performance of vertical-axis wind turbines have been conducted with the rotors in steady, and thus somewhat artificial, wind conditions - with the result that turbine aerodynamics, under varying wind ...
