A and B are constants. A describes the slope of the regression line and B is the
intercept.
3. Use the constants A and B in the above equation with data measured at Hvide
Sande over the period January 1989 to October 2002 to generate a longer
interpolated data series for Horns Rev. This can be used to calculate an average
wind speed and as input to the WAsP model to generate energy density,
potential power production for a given wind turbine, and Weibull shape and
scale parameters. It should be noted that the directions used in the time series are
those from Hvide Sande. Directions from Hvide Sande and Horns Rev during
the overlap period are compared and shown in Figure 4.2
The regression line can either be fitted through the origin or with an intercept depending
on which gives the best fit to the data. A summary for all data using both methods is
given below.
Fit 1: Linear
Equation Y = 1.1277 * X + 1.6885
Number of data points used = 29606
Average X = 6.889
Average Y = 9.458
Coefficient of determination, R-squared = 0.7111
Fit 2: Through origin
Equation Y = 1.328 * X
Number of data points used = 29606
Average X = 6.889
Average Y = 9.458
Coefficient of determination, R-squared = 0.6836
Since linear fit gives the highest r 2 , this fit has been used in the following analysis, and
is the line shown in Figure 4.1.
