WebOct 1, 2006 · This paper compares between two commonly used functions, the Weibull and Rayleigh distribution functions, for fitting a measured wind speed probability distribution at a given location over a certain period. Hourly measured wind speed data at 10 m height for the years 2003 to 2005 have been statistically analyzed for the Kingdom of Bahrain. The … http://ijmrr.com/admin/uploads/6.pdf
WebFeb 15, 2013 · The Weibull distribution, however, has been found to produce a better fit to observed wind speeds than the simpler Rayleigh distribution . Nevertheless it is problematic fitting a Weibull distribution at low wind speeds, as highlighted by Justus et al. (1976) , who assessed potential output from wind-powered generators. WebThe significance of this is that manufacturers assume a Rayleigh distribution in estimating the energy a turbine would produce given a certain wind speed. The DOE wind energy …
