Your Questions About Wind Turbine Generators For Home Use

Donald asks…

How is electricity produced for the electric companies ?

Where do they get theyre power to power all the homes and businesses ?
&&
How do they keep getting power ?
Do they ever run out ?

admin answers:

Electricity supply is produced by large Power Generation Stations and sold to the distribution Companies who then distribute and sell it to the users.
The Power Generation Stations, consist of various types of Industrial Plants:
1…Burning of Fossil Fuels…Oil, Coal or Gas which are used to produce vast amounts of high pressure, high temperature (superheated) steam. This steam is used to drive (rotate at high speed), huge Steam Turbines which are connected to large Power Generators that produce the Electricity into a ‘Power Grid’ network which feed the electrical companies who then supply the Industrial and domestic users.

2..Combustion Gas Turbines use the Energy of an Expanding mixture of Superheated Air and Combustion Gases to drive high speed turbines that drive Power Generators….and so on..as above.

3..Use of Rivers or Lakes behind dams. The huge volumes of flowing water from these sources provides massive amounts of Kinetic Energy which is utilised to drive large Water Turbines which, in turn drive Power Generators….the rest is as above.

4..Wind Turbines are used to do exactly he same thing…A large ‘Propeller’ type windmill drives a generator…etc.

5..Nuclear Power plants use the tremendous heat of atomic fission to produce vast amounts of high pressure, high temperature (superheated) steam. This steam is used to drive (rotate at high speed), huge Steam Turbines…etc.

In each case, the Kinetic Energy of the power source is converted to Mechanical Energy (Turbine) and then into Electrical Energy (Generator)..

Joseph asks…

How is energy from a wind turbine transferred to the national grid ?

Isn’t the current DC ?

Answer #3 was sort of right. You are correct, because of the variances in speed, those generators tend to be DC machines. From the wind turbine the “juice” is fed to inverters that can be phase controlled as well. The DC, after conversion to true sine wave AC, and phase locked to the grid system, and it’s voltage adjusted for the feed point where it will be added in, is switched into the grid system at that point. Best use, unless you have millions to invest in wind turbines and the hardware to go with it, is to use the power at your home, yourself.
