An instrument that measures the speed and force of the wind. The most basic type of anemometer consists of a series of cups mounted at the end of arms that rotate in the wind. The speed with which the cups rotate indicates the wind speed. ...
The model, which utilizes wind speed measurements from neighboring locations and combines the extreme learning machine (ELM) with the AdaBoost algorithm, is named the multiple-point-AdaBoost-ELM model. Data from seventeen automatic meteorological stations in the Heihe River Basin are used, four ...
Finally, by including wave-attenuation effects between the WF and the TNS observatory, we are able to precisely predict the noise signal amplitude at TNS based on near-field measurements. This novel approach is suitable to estimate the seismic noise field produced by WFs and to predict the ...
wind speed measurements collected at the site and used to calculate the number of hours observed for each wind speed class. A rough estimate of annual electric production in kilowatt-hours per year at a site can be calculated from a formula multiplying average annual wind speed, swept area of...
For example, for Alpha Ventus wind farm, the capital cost per MW exceeds €4 million (see Figure 44) due to the demonstrative nature of the project (being the first large-scale offshore wind farm located in transitional waters). Nevertheless, increased offshore wind power costs, on top of...
It is found that within the measurement uncertainties the results of the wake model compare well with the measurements for the most important ambient conditions. The effect of the low turbulence intensity offshore on the wake development is modelled well for Vindeby wind farm. Deviations are found...
As a result, the wind farm production dynamics for a farm of 100 turbines at 10,000 different sets of ambient conditions run on a normal laptop in 1 h.The method is validated against full scale measurements from the Smola and OWEZ wind farms, and fair agreement is achieved. Copyright ...
Detecting Wind Farm Impacts on Local Vegetation Growth in Texas and Illinois Using MODIS Vegetation Greenness Measurements 来自 dx.doi.org 喜欢 0 阅读量: 28 作者:Xia Geng,Zhou Liming 摘要: This study examines the possible impacts of real-world wind farms (WFs) on vegetation growth using two ...
In this study, wind farm noise did not appear to effect traditional sleep measurements, including the time taken to fall asleep and time spent asleep during the night. "Well-controlled studies of wind farm noise on sleep are lacking, despite people's complaints and the known effects of other...
