Hi there,
I have been trying to get a question answered and am running into road blocks, could anyone possibly help in this area?
Here's the scenario
Imagine a 3 phase induction turbine, similar to what's used for wind mills. Smaller ones (say a 4 - 10' for diameter blade configuration) are "geared" to operate at peak efficiency around 20 - 25 mphs about 10-12 m/s - (I think that's turning the shaft at 500 rpm up to about 1200 rpm). This is so because that's what average wind speeds usually are and they are designed to generate power at low wind speeds. What if you had a consistent high wind speed? Is it possible to "gear" or modify these turbines for peak efficiency at 45 to 65 mph? For example, instead of the typical configuration which is: begin working at 7 mph winds and peak (for efficiency) at 25 mph could it be modified to cut in at say 25 mph and peak at 45 mph? OR, Could an alternator be purchased separately (sort of "off the shelf") and then it's rotating shaft be "fit" for small wind blades.
Put simply, I need a 3 phase alternator (or whatever is most efficient for generating and storing) that runs at higher rpms efficiently without 30 metre diameter blades - space is an issue in this project. I thank you kindly for your consideration and any help you could provide me. Thanks a million, Pete
