Wind Resource and Ye Olde Weibull PDF

07/16/2010 7:05 AM

My head hurts. I'm using the Weibull probability density function to calculate how much wind falls into various "bins" between 1 and 25 m/s. Anyone have a spreadsheet that accounts for both the shape factor (k) and the scale factor (c)? All Mr. English Major (ahem) can do is look at someone else's graphs and feel uneasy because my graph kinda looks like that ....

Hello!

I would say that using an excell spreadsheet wont give you the "prettyest" result. Just download a free trial version of WasP, and that will be all. To work with it, also download the "wasp wizard", which will help you step by step to make the weibull function and a wind rose (wind direction distribution of the wind, of course this will be good if you have wind direction measurements!).

Make a TXT file with columns, in the first one place the date (any format should be fine, in wasp wizard you can pick your format), in the second one place the time, in the third the wind speed and in the fourth the wind direction.

The wizard will start asking for some base information like location (coordinates) and name and discription of site. Than it should ask you to upload a file, just pick the txt, and it will tell you what to do.

I think it is fairly easy, I used it during my study times for lab reports, and it looks quite better than the spread sheats I made in excell.

Hope this helps,

Freddy Alcazar
