Statistical analysis of wind power density of Kingdom of Bahrain Based on weibull and rayleigh distribution functions

الملخص EN

Aw research, the hourly measured wind speed data for years 2003 to 2005 at 10 m height for kingdom of Bahrain have been statically analyzed to study the characteristics of wind speed in winter, spring, summer and autumn.

The maximum average wind speed and power density were, respectively, 4.88 m / s and 137.96 W /m2 which were found to be in winter.

The minimum average wind speed and power density were found to be in autumn which were, respectively, 4.02 m/s and 85.38 W/m2.

The annual average wind speed was 4.56 m /s and the annual average wind power density was 114.56 W/m2.

In addition, Weibull and Rayleigh distributions have been determined for each season.

The average wind speed and power density have been calculated using Weibull and Rayleigh distributions and compared with those calculated from the measured wind speed data.

It was found that Weibull distribution provides more accurate results than Rayleigh distribution.
