In the present study the energy potential of wind for the Eastern Prov
ince of Saudi Arabia is investigated. A suitable Weibull distribution
is generated based on the data obtained for a duration of one complete
year at a costal location in northeastern Saudi Arabia. Comparison of
this model is made with the Rayleigh distribution of wind power densi
ties. Two horizontal-axis type of wind energy conversion systems which
operate at fixed rpm are considered and a model of quadratic power ou
tput function is used. It is found that the error in using the Rayleig
h approximation will be less than 10% of the full rated power density
level. (C) 1998 Elsevier Science Ltd. All rights reserved.
