Sound propagation from a wind turbine in a hilly environment
Sound propagation in the atmospheric boundary layer can be strongly affected by vertical gradients in the wind speed and air temperature, and by atmospheric turbulence. In addition, undulating terrain will either partly shield or focus sound waves, highly impacting sound exposure levels. These aspects become especially important in case of wind turbines present on a ridge, such placement often ...
متن کاملWind turbine sound power measurements.
This paper provides experimental validation of the sound power level data obtained from manufacturers for the ten wind turbine models examined in Health Canada's Community Noise and Health Study (CNHS). Within measurement uncertainty, the wind turbine sound power levels measured using IEC 61400-11 [(2002). (International Electrotechnical Commission, Geneva)] were consistent with the sound power...
متن کاملWind turbine end-of-life:
Wind power is growing fast all over the world, and in Sweden alone thousands of turbines has been installed the last few decades. Although the number of decommissioned turbines so far is very low, the rapid installation rate indicates that a similar rapid decommissioning rate is to be expected shortly. If the waste material from these turbines is not handled sustainably the whole concept of win...
متن کاملFatigue Life of Wind Turbine Structural Components
Modern mega watt class wind turbines are exposed to high and complex loads. At the same time the aim is to realize light weight and optimized structures. Compared to other industries the design lifetime of a wind turbine is very long. Applying simulation tools for the predictions of fatigue life is therefore essential. This paper presents the approaches for fatigue anaylses used in the wind ind...
متن کاملMeasurement and characterisation of radiated underwater sound from a 3.6 MW monopile wind turbine.
This paper describes underwater sound pressure measurements obtained in close proximity (∼50 m) to two individual wind turbines, over a 21-day period, capturing the full range of turbine operating conditions. The sound radiated into the water was characterised by a number of tonal components, which are thought to primarily originate from the gearbox for the bandwidth measured. The main signal a...
