Wind Farm Siting

You would need to produce the entire article, But from what you have put on, I would say the wind speeds were measured at two points, and then at two heights and the efficiency measured

basically the higher you go the better but gain is not linear

hope this helps

if its any consolation i once read a workshop manual for a forlift truck, and bearing in mind i had an idea what was written. neither me nor the other engineer could understand it

I'll try: The daily average for wind speeds at measured at Arlow and Bedrock were compared to the wind speeds reported at the same time at Mast **** at 33 m. This comparison shows that there was a relationship (matching) of some kind between these speeds reported.

The nature of that matching (correlation) is not determinable for the data provided.

(in my opinion the correlation of wind speed is less important than the length of time of winds above threshold needed, but that is probably another post.) later

The hight at which the wind speed is measured should be the same hight as the hub of the wind turbine that you are likely to use. This gives a nice correlation to potential energy recovery rates.

By measuring at several different locations you are eliminating the possibility that the wind is just a local event that may not be reliable.

With two or more wind speed measuring sites and the appropriate software you can match the wind speed to the topography and figure out where to locate the wind turbine towers and how many of them are required to justify the infrastructure costs.

Once this is done you can go to the finance people and show them the long term data that you have collected. Long term data taken 24 hours a day shows the consistency of the wind resource over a period of years. When this is coupled with the number of turbines that a site can carry you can derive the payback period at current electricity prices.

You just don't get to do the engineering without the money and you can't get the money without the data.
