winnd generators

Hi all

I hope I came to the right group :

My question is about wind generators

In case of having several wind generators where each one produces electricity, how do I combine their output to produce a single AC voltage with stable frequncy like 110VAC 60 hz .

I thought that the best is to use a electric generator that will be driven by an electric motor that will turn in 60 cycles per seccond and the stator of the generator will control the amplitude with some currernt regulation .

Both the motor and the stator will be driven by the wind generators in the proper way , I do not know how .

Any way can some one explain how this is done in practice ?

Thanks Bar Nash

Is your question about designing something electronic.

Actually it isn't really. It is about combining power from sources. The sources don't really have to be wind powered. Some of them could be solar.

What sort of electricity? DC or AC what sort of voltages? When the power goes up does the voltage change or only the current?

How much power are we talking about?

Can we specify the generators or is this already determined?

There may really be two steps here. You could combine the power in DC form and then convert to AC.

Another question is: Are we connected to the power mains? This can matter to the design because being hooked to the mains provides a reference

You need to give more information and work out the problem a bit further yourself.

There are many ways to get this job done. One of the cutest is to use induction generators in the windmills. This will allow you to combine the outputs by simply connecting them together with relays. The down side is that the induction generators are large and need to be spun fast enough.

How big a wind generator? AC or DC output from the windmills?

The simplest way is to buy one bigger wind gen. The easiest way is to charge batteries for each generator and draw current from the battery by a combining box using switching power supplies designed for the purpose.

The problem with using the generators , is unless AC is aligned in phase and frequency, it does not add well, in fact it can cancel itself out under some circumstances, so just driving a motor generator will NOt do it.

If you need to ask you would be better off buying a suitable control unit.

One of the ways on a domestic scale is to have the erratic wind power smoothed by a stack of batteries and then run a solid state inverter to generate the mains power from that.

Do the sums very carefully and survey the site before committing to wind power. The return scales with windspeed^3 so 8m/s average wind gives you more than twice the power output of 6m/s average wind speed. UK has publically available windspeed maps by the square kilometre.

It can be worthwhile if you are off grid.
