Question

If you have a wind turbine How do you send your excess power back to the national grid?

Answer 1

Contact your power company. They all have different policies. Some do not allow it at all. Some do only with equipment they provide, at a steep price. Some allow you to buy the equipment, from an approved list, but require it to be installed by them.

Also depends on the state, county and town regulations, but the power company should know all of that.

This needs to be of a significant amount of power to make it worthwhile.

Answer 2

Why not send it to a leisure battery?  - Be completely self sufficient!

Most small scale wind turbines will not produce significant power, which would justify sending excess power back to a grid.  Better to save it for yourself (and possibly more efficient).

Of course, batteries are not ecologically sound.  What storage methods does the grid use, and are they more efficient than your method?

Answer 3

you must be in parallel IE same voltage same frequency and same slip angle.

once in parallel the building load will determine how much of the power from the wind turbine will be used or fed back into the grid.

basically there would be some control in the turbine to limit the power output otherwise it would overload when connected to the mains, the turbine just goes to full power out put, what is fed to the building load wont be seen by the boards power meter unless it is exporting to the grid.

because the meter is upstream of the turbine output any power feed to the building load will not show, any spare will be feed back in to the grid

Normally when synchronizing with the grid the voltage and frequency are slightly lower than the mains (droop).

the UK boards are putting provision into place for the future of local power generation. with regs like G59 and G5/4.

Answer 4

The secret is voltage. You set the output voltage of the turbine generator slightly higher than grid voltage. The generator and the house load and the grid are all in parallel, so when the load is greater than generator output, the excess will come from the grid. When the load is less than the generator output, the excess will go to the grid.

Answer 5

You need a special inverter whose frequency matches

itself to that of the Grid and whose voltage output is slightly higher.

Some utilities will license such a system and accept power from it.

When you feed the grid, your meter turns backwards.

Answer 6

Good question. Why doesn't the government implement eco friendly homes everywhere, which can support their own electricity supplies with wind turbines, solar panels, etc? There are so many better options than having to pay the power companies so much money every winter especially! Greedy schmucks. Eco homes are better for the environment too!
