Permanent land acquisition is generally based on the machine position of 25*25 meters. If there is a box type transformer, it must be added. The land occupied by the booster station is also the subject of permanent land acquisition.
Attempts to use wind energy to produce electricity began at the beginning of the 20th century. In the 1930s, Denmark, Sweden, the Soviet Union and the United States applied rotor technology from the aviation industry and successfully developed some small wind power devices.
This type of small wind turbine is widely used in windy islands and remote villages. The cost of generating electricity is much lower than that of a small internal combustion engine. However, electricity generation capacity at that time was relatively low, generally less than 5 kilowatts.

China's development situation:
In 2006, China had a total of 6,469 wind turbines, of which megawatt-level units accounted for 21.2%. In 2007, this proportion jumped to 38.1%, an increase of 16.9 percentage points. In 2007, the cumulative installed capacity of global wind power reached 94,100 MW, an increase of 27% from 74,200 MW the previous year.
In 2007, China's installed wind capacity was 6.05 million kilowatts, reaching the target set for 2010 three years ahead of schedule; in the six years from 2001 to 2007, the installed capacity of wind power in China increased 14 times; In 2007 alone, China's installed wind power capacity increased by 3.449 million kilowatts, more than the totalal cumulative wind power of China in history. With the rapid development of the wind power industry, the supply of wind power equipment exceeds demand.

Compensation standard for wind power generation land area
Would you like to ask the Dali County, Weinan City, Shaanxi Province In the distributed wind power project, how much area does the distributed wind turbine assembly occupy? According to the announcement from Xinxing Company, owner of the wind power project, the production unit covers an area of approximately 35 square kilometers.
The distributed wind turbine has a total installed capacity of 20 MW and covers an area of approximately 35 square kilometers. It is planned to be designed as 8 single machine generator units with a. wind capacity of 2.5 MW.
This will also be Sinopec's first wind project. Once completed, the power connected to thenetwork will be able to reach 42.865 million kilowatt hours/year, which is equivalent to a saving of 13,200 tons of standard coal per year, and can actually be achieved. reduce carbon dioxide and soot emissions.
How much area does the wind power transmission tower occupy?
The compensation standards for wind power transmission towers are as follows:
1. land expropriation, with the average compensation of 5.3 per mu for dry land, the average compensation for rice fields is 90,000 yuan per mu, and the average compensation for vegetable fields is 150,000 yuan per mu ;
2. Compensation standards for expropriation of basic agricultural land, average compensation of 58,000 yuan per mu for dry fields, 99,000 yuan per mu for rice fields, and 156,000 yuan per mu for vegetable fields
3. forest and other lands The average compensation for agricultural land est of 138,000 yuan per mu
4. The average compensation for expropriation of industrial and mining construction land, villagers' houses, roads and other collective construction land is 136,000 yuan; by mu;
5. Expropriation The average compensation for waste land, barren mountains, waste land, waste ditches and waste land is 21,000 yuan per mu.
Wind power is generated by converting the kinetic energy of wind into mechanical kinetic energy, and then converting the mechanical energy into electrical kinetic energy. The principle of wind power generation is to use wind energy to rotate the blades of the wind turbine, then use a speed multiplier to increase the rotation speed to induce the generator to produce electricity. According to wind turbine technology, electricity production starts at breeze speedabout three meters per second (the degree of breeze). Wind power requires no fuel and produces no radiation or air pollution. The equipment needed to produce wind energy is called a wind turbine. Wind turbines can be divided into three parts: the wind wheel, the tail rudder, the generator and the tower. (Large wind power plants basically do not have tail rudders, and only small ones (including domestic types) have tail rudders)
Legal basis
"People's Republic of China Article 47 of the Land Management Law of the Republic of China stipulates that in the event of expropriation of land, compensation shall be paid in accordance with the original purpose of expropriated land Compensation fees for the acquisition of agricultural land include land compensation fees, resettlement subsidies and compensation fees.for soil attachments and young crops. Land compensation costs for the expropriation of cultivated land will be six to ten times the average annual value of production for the three years preceding the expropriation of cultivated land. Resettlement assistance for the acquisition of cultivated land will be calculated on the basis of the number of agricultural people to be resettled. The number of agricultural persons to be resettled is calculated by dividing the area of expropriated cultivated land by the average area of cultivated land per person of the expropriated unit before land acquisition. The resettlement subsidy standard for each agricultural population to be resettled is four to six times the average annual value of production in the three years preceding the expropriation of agricultural land. However, resettlement aid for each hectare of expropriated cultivated land must not exceed fifteen times the valueaverage annual production of the three years preceding the expropriation.
100 square meters. The wind power transmission tower covers an area of 100 square meters. A 4.2 MW wind power plant occupies approximately 100 square meters, which is equivalent to 0.15 acres of land. in electrical energy. Wind energy is a clean and pollution-free renewable energy that has been used by people for a long time, mainly through windmills to pump water, grind flour, etc. People are interested in how to use wind to generate electricity.
