Hello, it depends. 1 If the negative work done by the wind on the object is greater than the sum of the positive work done by the wind itself and the positive work done by gravity on the object, then the combined speed of the object will decrease. 2 If the negative work done by the wind on the object is less than the sum of the positive work done by the wind itself and the positive work done by gravity on the object, then the combined speed of the object will increase. For example, if the wind force and gravity are in the same direction, then the wind force does positive work on the object and the object's speed increases. The wind force is opposite to gravity, so the wind force does negative work on the object and the object's speed decreases. The wind force is perpendicular to gravity, the wind force accelerates the object in the horizontal direction, and the wind force does positive work. If there is an angle between the wind and gravity, then consider the relationship between the positive and negative work done by the wind and the positive work done by gravity. Only by analyzing the above points 1 and 2 can we determine whether the speed of the object is increasing or decreasing.
A large wind power fan can generate 0.1 kWh of electricity in one revolution.
A 100kw wind turbine generates 0.1 kWh of electricity per revolution at rated speed. Usually, wind turbines from 50W to 300W are all 12V, and wind turbines from 300W to 800W are all 24V wind turbines. Above 800W, all wind turbines are above 36V.
The speed of the wind wheel is related to the speed of the wind, the size of the wind wheel, the number and design of the blades and other factors. According to statistics, the speed of wind turbines currently on the market is generally between 10-20 rpm, and the speed of large wind turbines is about 15 rpm.
The power generation of wind power is mainly affected by the wind speed and the rotation 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 generation will be reduced accordingly; when the wind speed is high, the speed of the wind wheel will also increase, and the power generation will also increase accordingly.
Development Trends of Wind Power
In the future, the development of wind power will be more intelligent, efficient, low-carbon, and digital. In terms of technology, the future will strengthen the reliability, safety and stability of wind turbines, improve wind energy conversion efficiency, and make full use of digital technology and Internet of Things technology to achieve intelligent management and operation of wind power generation.
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 power. In practical applications, the power generation of wind power will be affected by many factors, such as topography, climate environment, equipment maintenance, etc. Therefore, the actual power generation of wind power may have certain fluctuations.
