Why the installation of large wind turbines represents a delay

The construction of windmills must be done over a large area where no one lives and where the wind is extremely strong.

Because the construction of windmills must be done over a large area where no one lives and where the wind is extremely strong. The reasons why local economies based on wind energy production cannot grow are as follows. Wind energy production is generally located in certain mountainous and desert areas. Mainly due to the low level of economic development in mountainous and desert areas, land prices are cheaper. The relief of mountainous areas being relatively rugged, means of transport are lagging behind. Desert areas experience poor climatic conditions, less precipitation and a backward economy.

A wind turbine is an electrical machine that does not require fuel and is usefuluses wind as energy. The first wind turbines were also called windmills. Modern wind turbines mainly refer to wind turbines used to generate electricity and are also used to extract water for irrigation.

What does it mean where wind power generation is installed?

You can do an experiment. Take 2 paper wind turbines and place them one behind the other in front of the fan to see. if the one in the back works, change.

Once the wind spins a generator to produce electricity, the wind energy is converted to kinetic energy and the wind energy is reduced. If there is a generator directly behind it, the wind energy received will be reduced.

Additional information:

1. As the poster says, if installed in a pipe the windmill on the back will spinnaturally, because when the wind blows from one end, it will inevitably blow from the other end, because the pipe changes the direction of the wind, forcing the wind direction disturbed by the windmill to return to its original direction. But wind turbines are built in nature and the wind flows freely without a pipe to hold it. The wind blows in one direction, and after passing the wind turbine, its direction is disrupted and its speed is reduced.

2. I don't quite understand this question.

The wind turbine rotates slowly because the wind speed at that time is slow. The faster the wind speed, the faster the rotation speed. The wind does not only blow between the blades, because the direction of the blades is not parallel to the direction of the wind, but at a certain angle. The wind blows on the blades, causing them to spin. During this process, the wind works on the blades and the kinetic energy of the wind is convertedie in kinetic energy of the generator.

Let's take an extreme example: the wind blows on a wall, the wall does not fall, the wind speed drops to zero and the wall receives an external force. If the wall collapses, the wind speed will not be zero, but the speed will slow as work is being done on the wall – the same principle as a generator.

-------------------------------------------- ----- -----------

2 additional:

1. As the poster says, air entering the duct is theoretically continuous. wind enters a uniform duct (same duct cross section) and the instantaneous velocity leaving the duct must be the same because there is no loss of air volume. This should make all the fans spin.

The condition we assume here is a cylindrical pipe with the same cross section. Since the wind direction remains unchanged, we have come to the above conclusion. The original supposed posterfirst have a small box with two opposite holes. If it's a square box (the kind with edges), it's hard to tell whether to open two holes on each opposite side. Since gas swirls will occur in the corners of the square box, we also need to consider various changes in the gas inside the box. . . Very complicated. If you are interested, I suggest you read some books on fluid mechanics.

2. When the fan blades are stationary, the gap between them is indeed large; but once the fan blades rotate, the gap between them will become smaller. For example, when an electric fan is running, can you see the spaces between its blades? ----can't. But when you turn off the switch, the fan blades spin slower and slower and the gaps become more and more obvious.

Thus, when the pathe wind turbine is stationary or rotating slowly, there will be breeze or air passing between the blades; when the wind speed increases and the blades spin faster and faster, there will be no wind. gaps.

Can I see under the wind turbine?

The location where wind power is installed represents the development and use of renewable energy, and the beginning of clean energy replacing traditional energy. Wind power has the advantages of environmental protection, renewable and distributed energy production, and is an important choice for the development of renewable energy.

The locations where wind power generation is installed are generally in places with abundant wind resources, such as coasts, mountains, plains, etc. When selecting a site, factors such as wind resource conditions, impactt environmental, construction cost, construction time and equipment reliability must be considered to ensure power generation efficiency and economic benefits.

Where wind power is installed, it not only represents the development of renewable energy, but also provides an important basis for regional economic and social development, such as increasing the local employment rate. , promoting local economic development, improving local conditions. environment, etc.

Hello: Question: Will the rotation of wind turbines affect the accumulation of dark clouds in the sky, resulting in reduced precipitation.

Yes.

Wind power generation is one of the electricity generation methods with the most mature technology, largest scale and commercial development prospects in the field.ine of new energies. The development of wind power is of great importance to ensure energy security, adjust the energy structure, reduce environmental pollution and achieve sustainable development.

The principle of wind power generation is to use wind energy to rotate the blades of the wind turbine, and then use a speed multiplier to increase the rotation speed to encourage the generator to produce electricity. Depending on the purpose of wind turbine technology, electricity can be produced with just a slight breeze. Wind energy is gaining popularity around the world because it poses no fuel problems and does not produce radiation or air pollution.

This will not reduce the amount of rain. The wind blows originally from your house Even if you don't worry about the windmill, the wind will blow from your house. reason for locatione wind energy production, it only converts wind energy into electrical energy and has no impact on the climate. Your location is suitable for wind power generation. Rain has nothing to do with wind power installation.
