How does wind power generate electricity, and how much electricity can be generated by wind power

A set of wind power generation equipment should be composed of three parts: wind turbine, storage battery, and inverter power supply.

According to the electrical appliances used to choose the inverter power supply: choose the inverter power supply higher than the power of the electrical appliances, such as a color TV, a VCD, two a total of 160W, the inverter power supply should not be less than 200W; Even if you use small power most of the time, only a short time to use larger power appliances must be configured according to the maximum power inverter power supply, for example, a family generally only uses color TV and satellite receiver, which is generally 200W inverter power supply is enough, but you need to use a 1000W rice cooker when cooking, although it only takes 30 minutes, then 1000W inverter power supply is also the most basic choice; In addition, if there are refrigerators, air conditioners, water pumps, motors and other inductive loads in electrical appliances, they should generally be X3 times when purchasing, such as vegetable greenhouses or fish farms need to use 750W water pumps, then in order to work for a long-term, reliable and stable time, it is necessary to purchase 2000W inverter power supply.

Wind turbine according to the time of use: the inverter power supply depends on the power of the electrical appliances, and the length of the use of these electrical appliances depends on the power generation of the fan, assuming that the family uses 500w electrical appliances for 6 hours a day, and the local air volume is very large, it can reach an average wind speed of 7 meters per second, then the selection of 200w fan is enough, but if the use of electrical appliances is powerful, the use of a long time or the local air volume is small, a larger power fan should be selected to ensure sufficient power supply.

The selection of the battery is calculated according to the following empirical formula: battery capacity (electrical power battery voltage) usable time, for example, the electrical power is 200W, the battery capacity is 100Ah, the voltage is 12V, and the battery is sufficient: 100 (200 12) hours.

I know about wind energy billboards.

It mainly relies on electric motors to store the energy brought by the wind.

to a certain extent.

Then release it.

600 words? It's that complicated.

According to the principle of electromagnetic induction, when the conductor cuts the magnetic inductance line, the two ends of the conductor will generate induced electromotive force, and the coil is connected to a certain circuit with a brush, and the electric energy is stored.

A windmill can generate electricity once it turns.

The power of different engines is different, in the case of relatively stable wind energy, it can generate 2000 kWh of electricity in 60 minutes, and the average can generate electricity per second, and the amount of electricity that can be generated in one turn is the kWh. Of course, this data is not completely accurate, it will be limited by the influence of wind and the generator itself, and the technology related to solar energy is not mature enough, and due to the high cost, it is not put into use in large quantities.

However, there are still many people who are still committed to the research of this energy field, and this energy will also bring great changes to people's lives in the future, and those power generation methods with poor conversion rates and bad environmental impacts will gradually change in the future.

The principle of windmill power generation

The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through the speed increaser to promote the generator to generate electricity. The blades are used to receive the wind and convert it into electrical energy through the nose, the tail makes the blades always face the direction of the incoming wind to obtain the maximum wind energy, the rotating body can make the nose rotate flexibly to realize the function of adjusting the direction of the tail, the rotor of the nose is a permanent magnet, and the stator winding cuts the magnetic field lines to generate electricity.

Due to the unstable air volume, the wind turbine outputs 13-25V alternating current, which must be rectified by the charger and then charged to the storage battery, so that the electric energy generated by the wind turbine becomes chemical energy. Then, the inverter power supply with a protection circuit is used to convert the chemical energy in the battery into AC 220V mains power to ensure stable use.

For example, the most common 2MW direct-drive wind energy generator, when the wind energy is sufficient and stable, the wind turbine can generate 2000 kWh of electricity every 60 minutes.

It takes seconds for each rotation of the fan blades, 60 minutes is 3600 seconds, so the electricity generated by the generator per second is the degree, so the electricity generated by the wind jujube fan of the wind energy generator is the second per revolution, that is, the electricity.

1. (1) The advantages of wind energy: huge accumulation, wide distribution, renewable, and pollution-free.

2) Disadvantages of wind energy: low density, instability, large regional differences, wide area dispersion of wind energy, randomness and low density of energy!

2. Wind power generation: The advantages of large-scale systems are high reliability of system power supply and low operation and maintenance costs, and the disadvantages are high system cost

The advantages of the small system are that the system has a higher power generation, the system cost is lower, and the operation and maintenance cost is low.

The disadvantage is that small wind turbines have low reliability

Due to the strong complementarity between solar energy and wind energy, the wind-solar hybrid power generation system makes up for the lack of resources of wind power and photovoltaic independent systems.

Sink. A wind turbine is an energy conversion device that converts wind energy into mechanical energy.

As shown in Figure 1-4, the wind turbine consists of five parts:The disadvantage is that it is more difficult to start...The capacity of small wind turbines is not large, and the power is generally from a few watts to several kilowatts, and most of them have the advantages of simple structure and easy handling

Energy storage is an important issue in the utilization of wind energy...

3. The advantages of wind power generation are:

The cost of solar power generation is too high, the technical content is high, and the power generation will be affected when the weather is bad;

In wind power, the worse the weather and the stronger the wind, the better the power generation.

The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through a speed booster to promote the generator to generate electricity. To put it simply, wind power generation is the process of converting wind energy into mechanical energy, and then converting mechanical energy into electrical energy. This process does not require fuel and radiation, and does not produce air pollution, which is a clean energy source.

At present, wind power generation is very popular in Finland, Denmark and other countries, and China has also begun to vigorously promote it in the western region.

Understand the working principle of wind power generation in 3 minutes.

Wind energy is used to drive generators to rotate to generate electricity. Environmental protection and energy saving.

Wind can be used for many purposes in addition to generating electricity.

Wind is the most mysterious thing in nature, and people use it to help people make a great contribution. Just like the clothes we usually wash, if the weather is cloudy, we can dry the clothes in a good ventilated place, so as to speed up the drying speed of the clothes, so that the water on the clothes can be better evaporated. It may take longer to dry your clothes than it would take to dry them in the daylight, but you can still blow dry them, so you won't have a problem wearing dry clothes.

Farmers still need the help of the wind to harvest their crops, such as wheat, and in some places the wheat that cannot be harvested by machine has to be done manually. Manually put the harvested wheat on the flat ground and drive out the wheat grains, the wheat that has just been pulled out has a lot of dust and wheat husks, at this time it is necessary to use the wind to blow the wheat clean, which is commonly known as "Yangmai" in our hometown. When the wind blows the wheat clean, the farmer can dry the wheat and put it in the warehouse or sell it.

We can also fly kites using the wind, and kite flying is one of the most fun recreational activities, both adults and children can play. When there is to be a wind, the kite string must be released a little bit and run in the opposite direction of the wind, so that the kite can fly slowly. Wait for the kite to fly steadily, and then slowly release the line, the stronger the wind can the kite fly higher, the farther it flies, if there is no wind, the kite can not fly at all, so the kite is also inseparable from the wind.

There are many roles of wind, people use wind to do a lot of things that are beneficial to people's lives, and it has been closely related to people's lives, and we are surrounded by wind all the time. Whether it is cool or cold, it is the mysterious power of wind in nature, the power of wind is huge, as long as it is used well, it will definitely bring greater gospel to people.

Wind energy is the kinetic energy produced by the massive movement of air on the earth's surface. Because the temperature of the ground will be different when the sun irradiates it, the content of water vapor in the air will also be different, which will cause the difference in air pressure in different places, so that the wind will be formed when the high-pressure air flows from the horizontal direction to the low-pressure area. Wind energy is a renewable, non-polluting energy source with a large amount of energy stored and leaked.

The principle of wind power generation is very simple, if the wind blows the wind on the generator to rotate, the wind blades will drive the generator to block the disadvantages to produce electricity. Wind energy is not only a renewable resource, but also does not pollute the environment, so now countries around the world are vigorously developing wind power generation.
