2. This depends on the situation. If it's a mining machine of the size of USB flash disk, the computing power is only about 1g. This mining machine is a kind of experience machine. Let alone 20, it doesn't matter if there are several hundred. But if it is the kind of professional mining equipment, ordinary household electricity is simply not up, mining machine power and power consumption is very high. Moreover, the noise of mining is very large, and the heat generated is also very large. There must be powerful refrigeration equipment, which also needs power consumption

3. It depends on the capacity of a single machine (850kW, 1MW, 1.5MW, 2MW, 3MW, etc.) and the operation of wind power. One kilowatt hour power = 1kW · h, according to this calculation, 850kW wind turbine can generate 850 * 24 = 20400kw · h every day, which is the theoretical value. Also depends on the wind situation, power transmission loss and so on.

Advantages:
1, clean, good environmental benefits
2. Renewable and inexhaustible
3. The construction period is short, and it can be built on land or at sea
The installation scale is flexible and the cost of operation and maintenance is lowwind power generation is to convert the kinetic energy of wind into electric energy. The wind energy in the world is about 2.74% × 10 ^ 9mw, of which the available wind energy is 2 × 10 ^ 7mw, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth
As a kind of clean energy, wind energy has great attraction in the 21st century when resources are scarce and environmental problems are prominent. Wind power generation technology is widely developed in the world to replace the traditional coal and fuel thermal power. In terms of wind power development, Germany, Denmark and other countries are more advanced. Although China's wind power has a greater development than before, there is still a big gap with the world's advanced level 
extended data
wind turbine is mainly composed of two parts: wind turbine part, which converts wind energy into mechanical energy; wind turbine part, which converts wind energy into mechanical energy; Generator part - it converts mechanical energy into electrical energy
classification of wind turbine:
1. Horizontal axis wind turbine, the rotating axis of wind wheel is parallel to the wind direction
2. Vertical axis wind turbine, the rotating axis of the wind wheel is perpendicular to the ground or the direction of air flow
There are two types of horizontal axis wind turbine: lift type and drag type. The speed of lift type wind turbine is fast, while that of drag type wind turbine is slow. For wind power generation, lift type horizontal axis wind turbine is often usedmost horizontal axis wind turbines have wind facing devices, which can rotate with the change of wind direction. For small wind turbines, the tail rudder is used, while for large wind turbines, the transmission mechanism is composed of wind direction sensor and servo motor
The vertical axis wind turbine does not need to face the wind when the wind direction changes, which is a big advantage compared with the horizontal axis wind turbine. It not only simplifies the structure design, but also reces the gyroscopic force of the wind wheel when the wind direction changes5. If the wind speed reaches supersonic speed, for example, ring re-entry.
6. Engine room: the engine room contains the key equipment of wind turbine, including gearbox and generator. Maintenance personnel can enter the engine room through the wind turbine tower. The front end of the engine room is the wind turbine rotor, namely the rotor blade and shaft
rotor blades: capture the wind and transmit it to the rotor axis. On a 600 kW wind turbine, the measured length of each rotor blade is about 20 meters; On a 5 MW wind turbine, the blade length can reach nearly 60 meters. The blade design is very similar to the wing of an aircraft, but the manufacturing materials are very different, and the fiber is used more than the light alloy. Most rotor blades are made of glass fiber reinforced plastic (GRP). Using carbon fiber or aramid as reinforcing material is another choice, but this kind of blade is not economical for large wind turbine. Wood, epoxy wood, or epoxy wood fiber composites have not yet appeared in the rotor blade market, although they have been developed in this field. Steel and aluminum alloy have the problems of weight and metal fatigue respectively. At present, they are only used in small wind turbines.. In fact, rotor blade designers usually design the cross section of the most distal part of the blade to be similar to the wing of an orthodox aircraft. But the thick profile of the inner end of the blade is usually specially designed for wind turbine. Choosing a profile for a rotor blade involves many tradeoffs, such as reliable operation and time delay characteristics. Blade contour design, even when there is dirt on the surface, the blade can work well
axis: the rotor axis is attached to the low speed shaft of the wind turbine
low speed shaft: the low speed shaft of the wind turbine connects the rotor shaft with the gearbox. In the general wind turbine, the rotor speed is quite slow, about 19 to 30 rpm. There is a conit in the shaft for the hydraulic system to activate the operation of the pneumatic brake
gearbox: gearbox is a speed change device connecting low speed shaft and high speed shaft, which can increase the speed of high speed shaft to 50 times of that of low speed shaft
high speed shaft and its mechanical brake: the high speed shaft operates at more than 1500 rpm and drives the generator. It is equipped with emergency mechanical brake, which is used when the aerodynamic brake fails or when the wind turbine is repaired
generator: wind turbine generator converts mechanical energy into electrical energy. The generator on the wind turbine is different from the generator on the general power grid: the wind turbine generator needs to operate under the condition of fluctuating mechanical energy. The most commonly used wind turbine generator is inction motor or asynchronous generator, the latest wind turbine has started to use permanent magnet synchronous generator. At present, the largest power output of a single machine in the world is more than 6000 kW (E-112 / 114 of Enercon, Germany)<
yaw device: with the help of motor to rotate the engine room, the rotor blade can adjust the best cut in angle of wind direction. The yaw device is operated by the electronic controller, which can detect the wind direction through the wind vane. Usually, when the wind changes its direction, the wind turbine will only deflect a few degrees at a time. It is worth noting that small power level wind turbines adjust the angle of all blades through a unified yaw device, while the latest wind turbines mostly set a separate yaw system for each blade<
electronic controller: generally, one or more computers are used to continuously monitor the state of the wind turbine to control the yaw device. Once the wind turbine fails (i.e. the gearbox or generator overheats), the controller can automatically stop the wind turbine and inform the wind turbine management center through network signal
hydraulic system: used to reset the aerodynamic brake of the wind turbine.
rotor blades: capture the wind and transmit it to the rotor axis. On a 600 kW wind turbine, the measured length of each rotor blade is about 20 meters; On a 5 MW wind turbine, the blade length can reach nearly 60 meters.

7. As long as the wind power of 1000W generator is sufficient, it can output rated power of 1000W. However, if the electrical equipment is inctive electrical equipment, the power factor should be considered. Generally, the power factor can reach 0.85, that is to say, your generator can drive 850W inctive load. Emotional load, washing machine, range hood, refrigerator, air conditioner....
8. The power of the wind is huge, we are familiar with tornadoes, typhoons have turned to show the power of the wind. If we can make rational use of the wind, it can also serve us, such as the use of wind power
the principle of wind power generation is to use the wind to drive the blades of the windmill to rotate, and then increase the speed of the rotary drill through the speed-up engine to make the generator generate electricity. According to the current windmill technology, from the economic and reasonable point of view, wind speed greater than 4 meters per second is suitable for power generation. As a clean and renewable energy, wind energy has low cost and does not pollute the environment. It is a kind of environmental protection energy, and has been paid more and more attention all over the world. Its disadvantage is that the source is not stable, and the wind is different with different seasons.

the principle of the wind turbine is to use the wind to drive the blades of the windmill to rotate, and then increase the rotating speed through the speed-up engine to make the generator generate electricity. Converting wind energy into electricity is the most basic way of wind energy utilization. Wind turbine generally consists of wind wheel, generator (including device), direction regulator (tail wing), tower, speed limiting safety mechanism and energy storage device. Ultra low speed wind turbine is a system composed of rotating disk, fixed disk, wind wheel blade, fixed wheel, vertical pole, collector ring disk, rudder rod, tail rudder and inverter. The generator consists of a rotating disk and a fixed disk. The inverter consists of a 50 Hz sine wave oscillator, a shaping circuit, a low-voltage output circuit and an inverted phase push-pull circuit. The advantages of the generator in this system are as follows: first, it has the characteristics of ultra-low speed voltage building, and can generate power normally when the blade speed is lower than 100 rpm, which provides a new way for the development and utilization of wind resources in weak wind areas; Second, the structure is simple, the iron core has no slot, and there is no armature winding, so it is easy to maintain and has long service life.
the principle of wind turbine is to use the wind to drive the wind turbine blades to rotate, and then increase the rotation speed through the speed-up engine to promote the generator to generate electricity. According to the current windmill technology, the wind speed is about three meters per second (the degree of the breeze), and power generation can be started
wind power generation is becoming an upsurge in the world. There is no fuel problem, radiation or air pollution for wind power generation
wind power is very popular in Finland, Denmark and other countries; It is also strongly advocated in Western China. Small scale wind power generation system has high efficiency, but it is not only composed of a generator head, but a small system with certain scientific and technological content: wind turbine + CHARGER + digital inverter. The wind turbine is composed of head, swivel, tail and blade. Each part is very important, the function of each part is: the blade is used to receive the wind and turn it into electric energy through the machine head; The tail makes the blade always face the direction of the wind, so as to obtain the maximum wind energy; The swivel can make the nose rotate flexibly to realize the function of tail adjusting direction; The rotor of the machine head is a permanent magnet, and the stator winding cuts the magnetic line of force to generate electric energy
e to the unstable air volume, the output of wind turbine is 13-25v alternating current, which must be rectified by charger, and then the storage battery is charged, so that the electric energy generated by wind turbine can be changed into chemical energy. Then, the chemical energy in the battery can be converted into AC 220 V commercial power by using the inverter with protective circuit, so as to ensure the stable use
it is generally believed that the power of wind power generation is completely determined by the power of wind turbines, and people always want to buy larger wind turbines, which is not correct. At present, the wind turbine only charges the battery, and the battery stores the electric energy. The size of the electric power that people eventually use has a closer relationship with the size of the battery. The power mainly depends on the air volume, not only the power of the head. In the mainland, small wind power generation opportunities are more suitable than large ones. Because it is more likely to be driven by small wind and generate electricity, continuous small wind can supply more energy than a gust. When there is no wind, people can still use the power brought by the wind normally, that is to say, a 200W wind turbine can also get 500W or even 1000W or more power output through the combination of large battery and inverter
the use of wind turbines is to continuously turn wind energy into the standard electricity for our families. The degree of saving is obvious. A family only needs 20 yuan of battery liquid for one year. However, the performance of the wind turbine now is much better than that of a few years ago. In the past, it was only used in a few remote areas. The wind turbine connected to a 15W light bulb directly uses electricity, and the light bulb is often damaged when it is bright and dark. Now, e to technological progress and the use of advanced chargers and inverters, wind power generation has become a small system with certain scientific and technological content, and can replace the normal power supply under certain conditions. Mountain area can use this system to make a street lamp without spending money all the year round; It can be used as a night light on expressways; Children in mountainous areas can study by themselves at night under fluorescent lamps; Wind turbines can also be used on the top of small high-rise buildings in cities, which not only saves energy, but also is a real green power supply. Household wind turbines can not only prevent power failure, but also increase the interest of life. In scenic spots, border defense, schools, troops and even backward mountainous areas, wind turbines are becoming a hot spot for people to purchase. Radio enthusiasts can use their own technology to serve the people in mountainous areas in terms of wind power generation, so that people can watch TV and use electricity for lighting at the same time as the city, and also make themselves rich through labor.
