Wind Fabric Diagrams and Their Application to Wind Energy Analysis

Abstract

By means of the Lambert projection, wind vector data may be plotted onto a frequency map. The resulting diagram portrays the ?wind fabric? for the data sample of a single station or for groups of stations. The area-true distribution of wind vectors is thus given in great detail and allows several standard tests for homogeneity and anomaly significance. By using a ?swinging plate? device the wind energy density and wind power can be calculated for any velocity-compass heading sector of the diagram desired and allows for a universal scaling of the velocity variable of the diagram.
