selling excess power
selling excess power
(OP)
I have an idea that could produce 500kw excess power
at times. How large (physicaly) would a generator of
that size be? How much would it cost? Can I use the
generator as a brake by varying the output load?
Would the r.p.m. need to be constant in order to match
phase with the utility? Are there any programs sponsored
by utilities (or anyone else) that would help
technically?, financialy? I think my idea is valid but
I don't have the resources to see it through.

RE: selling excess power
Just to give you a frame of reference for visuallizing what's involved, a 500 kW induction generator could be around the size of an office desk and weigh somewhere around 5-6000 lb, depending on the operating voltage.
When you operate in parallel with the utility grid, the speed is set by the grid frequency, the only influence that your generator will have is how much power (real and rective) you generate.
You will also need to consider whether you need a synchronous or induction type generator, which influences the interaction with the grid.
