How many wind turbines should be installed on 7,000 acres of land?

Introduction How many wind turbines should you install on seven thousand acres of land? Two wind generators can be built on one acre of land, and 14,000 wind turbines must be installed on 7,000 acres of land. The spacing between large wind turbines is generally.

How many wind turbines should be installed on 7,000 acres of land?

Ten thousand and fourteen. Two wind generators can be built on one acre of land, and 14,000 wind turbines must be installed on 7,000 acres of land. The spacing of large wind turbines is generally 10 to 15 times the diameter of the wind wheel, which is one spacing. from 700 to 1,000 meters. Wind turbines are electrical equipment that convert wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current.

How does this 200 meter high wind turbine convert majestic wind into millions of watts of electricity?

First, the windshield turns the propeller and the rotor inside the top of the tower turns the drive shaft. The drive shaft is connected to a gearbox, thereby rotating the generator to produce electricity. It is not easy to build such a wind turbine. It starts with the propeller. The difficultyto make a propeller lies in the fact that each blade has a curved surface like that of an airplane. When the wind blows over the blades, it generates an upward force, causing the propeller to rotate. In addition, it must be sufficiently long and light. enough. Therefore, all blades are constructed from one piece of carbon fiber. Carbon fiber is stronger and lighter than steel and allows for longer blades.

Second, use fiberglass to make an aerodynamic shell. First vacuum-pack the fiberglass sheets, then bake them in this cylindrical oven to form two halves of a perfectly homogeneous shell. Anxious to join the two halves of the document, workers first applied a layer of glue to the inside of the bottom of the shell, then also applied it to the top of carbon fibers one and two, then carefully dropped the hugee 55 meter long car in the correct position. After the blade is installed, the blade must be fired again to allow the adhesive to change. After cooking, remove the combined document. At this time, the surface of the blade is not smooth enough and it needs to be polished with a sand mill. It takes about ten hours to polish each blade.

Third, in nature, the biggest threat to wind turbines is lightning. If lightning strikes a hollow propeller, it will quickly heat the internal air and cause it to expand, causing the blade to collapse. To avoid being struck by lightning, engineers will install copper bridges on the tips of the blades. This will allow the lightning to conduct current to the base of the blade and then to the ground, allowing the lightning to bypass the footprint and protect important features. generator components. Then we started to install the mini power stationon the wind turbine. This is called the nacelle, which is the heart of the generator. The huge reward can generate a lot of twisting force, but it only spins 30 times per minute. slow speed cannot produce electricity, so the gearbox in the generator converts the low speed, high torque rotation of the blades into high speed torque via the drive shaft drives the rotating magnet to the inside the generator. rotates, an electromagnetic field is formed, thus generating an electric current.

Fourth, such a generator can produce 3.5 million watts of electricity, enough to power more than 3,000 homes. Each time the magnet rotates, the anode and cathode exchange, creating an alternating current. The cathode and anode exchange frequency depends on the custom of the rotating propeller, but the power grid requires stable frequency power supply, so this converter is installedin the cabin, which can convert the alternating current generated by different wind speeds into a stable frequency. and send it to the power grid. FinishThe assembled cabin weighs 85 tons, which is larger than a double-decker bus. It and other rectangular parts must be transported in batches by truck, and its assembly takes three days after arriving at the installation site. Once assembled, these giant wind turbines will be able to provide the city with the electricity it needs.
