How to find Total Harmonic Distortion(THD) in power system model using wavelet toolbox?

I want to find out THD in distribution system model using wavelet toolbox. I have developed a distribution system simulation model using simulink and sim power systems toolbox and I am able to import voltage, current output signal from workspace into the wavelet toolbox, but I didn't understand how to get wavelet coefficients from the obtained plots. so please give me an appropriate method to find wavelet coefficients and THD of an output signal using wavelet tool box.

(I am using MATLAB R2009a version)

use the powergui button to analyze THD instead.
