Wind speed is a kind of non-stationary time series, it is difficult to construct the model for accurate forecast. The way improving accuracy of the model for predicting wind speed up to one-month ahead has been investigated using measured data recorded by wind farm. A forecasting method based...
wind", "average wind" and gusts. This is because the wind speed and direction at a particular location vary enormously from one second to the next. In weather forecasting, the instantaneous wind is therefore measured for 3 seconds, while the average wind is calculated over a period of 10 ...
In this paper, We measured a wind speed at several point from mast and boom and we analyzed the error of wind speed at each point of measurement. Also, we will suggest a correction method using the data curve fitting about errors of wind speed between each point of mounted anemometer. ...
Common values ofkfor measured wind speeds are around 2.0, with a typical range of 1.5 to 3.0. Higher values ofkindicate a narrower speed distribution (more constant winds). Because of the cubic nature of the wind power equation, lowerkvalues have higher average wind power densities for the ...
at the wind power forecast,this paper discussed two kinds of methods of using neural network to put numerical wind speed prediction into wind power prediction values according to the measured wind speed data and output power data from November to December 2011 in a northern large-scale wind farm...
The kata thermometer is a heated-alcohol thermometer; the time it takes to cool is measured and used to determine air current. It is useful for measuring low speeds in studies of air circulation. A stream of air striking the open end of a tube closed at the other end will build up ...
Adequate agreement is found between the calculated and measured phase speed using Doppler radar in the wave number range 1.9 10 cm. In the wave number range 0.05 0.5 cm, measurements of phase speeds were obtained by using two wave gages. The waves were mechanically generated without wind and ...
