Virtual Wind Speed Sensor for Wind Turbines

Journal of Energy Engineering, 2011
A data-driven approach for development of a virtual wind-speed sensor for wind turbines is presented. The virtual wind-speed sensor is built from historical wind-farm data by data-mining algorithms. Four different data-mining algorithms are used to develop models using wind-speed data collected by anemometers of various wind turbines on a wind farm ...

Estimating wind speed distribution

Energy Conversion and Management, 2002
The Weibull distribution is used to model wind speeds at four locations in Oman. The scale and shape parameters were estimated using three methods, the Chi-square method, method of moments and regression method. It was observed that the estimates using the Chi-squared method gave the best overall fit to the distribution of the wind data. Both the scale

Surface Wind Speed Distributions

1992
Abstract : Some weapon systems are sensitive to winds in the lowest layers of the atmosphere. Wind speed distributions and random wind speeds derived from the distributions are often required to help determine the operational capabilities of these systems.

Wind speed and wind power forecasting models

Energy & Environment
Sustainable energy resources have proved to be the best alternative in the wake of environmental degradation, depletion of ozone layer and ever-increasing demand for energy. Though wind energy is a promising resource, the non-linear nature and non-stationary characteristics of wind have remained a formidable challenge.

Extreme wind speeds in Croatia

2004
The Generalized Pareto Distribution (GPD) and its application to the statistical analysis of extreme wind speeds are discussed. Its main advantage is that it makes use of all relevant data on the high wind gusts produced by storms of interest, not just the annual maximum. Peak-over-threshold maximum, extracted fro sample data series to rpoduce a series

Modelling extreme wind speeds

2007
Very strong wind gusts can cause derailment of some high speed trains so knowledge of the wind process at extreme levels is required. Since the sensitivity of the train to strong wind occurrences varies with the relative direction of a gust this aspect has to be accounted for. We first focus on the wind process at one weather station.
