Hi guys:
I plan for fixed pitch variable speed turbine with :5 k watt ,220v at 1500 rpm.my house max load is less than 2.5 k watt.now ,what are my chance for design a turbine with 5 kwatt as max output.so that the rotor rpm will vary so that the output will vary from min 2.5 k watt to max 5 k watt??
I plan for 4 pole 1500 rpm SG.???
My Q is how to estimate the output of such generator when the rpm is less than rated 1500 ??for example at 900 0r 1200 rpm???

Dear Salah

You can find all the answers you need on this in my book: Small Wind Turbine Engineering - from idea to certification.
It is available on Amazon.com

Salah, please have a look at this thread: https://www.greenpowertalk.org/showthread.php?t=1507
It covers a lot of the topics about turbine design that could be relevant for you.
