A large wind fan can generate 0.1 kilowatt hours of electricity per revolution.
A 100 kW wind turbine generates 0.1 kWh of electricity per revolution at rated speed. Usually, 50W to 300W wind turbines are all 12V, and 300W to 800W wind turbines are all 24V. Above 800W, all wind turbines are above 36V.
Wind turbine speed is related to wind speed, size of the wind turbine, number and design of blades and other factors. According to statistics, the speed of wind turbines currently on the market is generally between 10 and 20 rpm, and the speed of large wind turbines is around 15 rpm.
Wind power generation is mainly affected by wind speed and rotational speed of the wind wheel. Generally speaking, when the wind speed is low, the rotation speed of the wind wheel will be slower and the power outputwill be reduced accordingly. When the wind speed is high, the speed of the wind wheel will also increase and the power will be reduced. generation will also increase accordingly.
Wind power development trends
In the future, wind power development will be more intelligent, efficient, low-emission carbon and digital. In terms of technology, the future will strengthen the reliability, safety and stability of wind turbines, improve the efficiency of wind power conversion, and make full use of digital technology and Internet of Things technology to achieve intelligent management and exploitation of wind energy production.
In terms of policies, support and policy guidance for clean energy will be strengthened in the future to improve the market competitiveness and sustainable development of wind energy. InPractical applications, wind power generation will be affected by many factors, such as topography, climate environment, equipment maintenance, etc. Therefore, actual wind power generation may exhibit some fluctuations.
Does wind energy have an impact on the environment?
The ten characteristics of wind energy are renewable , widely distributed, relatively stable, non-renewable. -pollutant, limited by environmental conditions, impact on wildlife, high initial investment, sound and visual interference, regionality, seasonality.
1. Renewable
Wind energy is abundant and does not have the same depletion problem as fossil fuels and other resources.
2. Widely distributed
99% of the world's regions are suitable for wind energy production, especially open coasts and areas ofDeserts and other terrain conditions are particularly suitable.
3. Relatively stable
Although wind power generation has differences in seasons, periods and locations, compared with clean energy sources such as solar and hydropower, Wind energy production is predictable and flexible.
4. Non-polluting
Wind energy does not produce harmful emissions such as carbon dioxide like fossil fuels and does not pollute the environment.
5. Limited by environmental conditions
Environmental conditions such as wind speed, wind direction, topography and ocean air flow have a significant impact on wind energy. Electricity has an impact, affecting the stability and reliability of wind power generation to a certain extent.
6. Impact on wildlife
Wind turbines cause damages to birds and other wild animals, and their impact on their migration, habitat and reproduction is also gradually raising concerns among people.
7. High initial investment
The price of wind turbine equipment is relatively high, and the construction and maintenance costs are also high, requiring large investment.
8. Noise and visual interference
Wind turbines will produce noise and visual interference which will affect their appearance when in operation.
9. Regionality
Wind power is very regional and cannot be built anywhere. It must be built in a location with abundant wind resources. In other words, the wind speed is high and the duration is long. The size of wind resources is related to terrain and landforms, and mountain passes and islands are often the preferred locations.
10. Seasonality
The seasonality of wind power determines that wind power generation plays a “supporting role” in the overall power grid.

The subtropical monsoon climate is suitable for wind power generation
< p>The impact of wind during farm construction on the environment p>1 Analysis of atmospheric environmental impact The most significant impact on ambient air is dust.< /p>
2 The analysis of acoustic environmental impact is mainly the noise of construction machinery. generated by wind turbines.
3 Analysis of the environmental impact of surface water. Wastewater comes from the temporary housing area during construction.
4 Impact on cultivated land There is a small amount of cultivated land. near the wind farm. Try to avoid occupying landare grown during construction to reduce the impact on local farmers.
5 Impact on ecological vegetation, the base of the wind turbine, the base of the tower. road construction will cause some damage to soil and vegetation.
6 Impact on soil erosion. The wind farm occupies a small area and the amount of civil works is small. The excavation and filling of the wind turbine foundation will produce waste slag, and the amount of waste slag is small. Strengthen the management of the storage yard for earthworks and backfilling. formulate measures such as compaction of the earthwork surface, regular water sprays and covering.
7 Impact on birds. When installing wind turbines, erecting meteorological measuring towers and constructing roads and other facilities, noise, dust, etc. may occur. will interfere with the environmente original life of birds, making it impossible for birds around the site to feed, nest and reproduce normally. Since the construction period of the wind farm is short and the site is very small compared to the whole area where the birds live, and the birds themselves have the instinct to avoid danger and to migrate to other similar living environments to survive, the construction period is long. is very The impact on birds is not significant and will not result in a reduction in bird numbers.
Suitable. The subtropical monsoon climate has sufficient wind resources. The subtropical monsoon climate is mainly distributed in Asia, including southern China, Southeast Asia, India and other places. These regions generally have obvious seasonal wind changes, with stronger winds in summer and autumn and stronger winds in summer.you. weaker winter and spring,At the same time, due to the complex terrain, such as mountains, hills and other landforms, the installation area of wind turbines can be increased and the utilization rate of the wind turbine wind energy can be improved.
