The operating wind speed range specified for wind turbines is generally

3 ~ 25 m/s. Because it is necessary to protect the safety of wind turbines and provide appropriate customs, the specified operating speed range of wind turbines is generally 3-25m/s. The general start-up wind speed of wind turbines is 3 to 4 m/s, and the cut-off wind speed, that is, the wind speed when stopping in strong winds, is 19 to 25 m/s. The so-called standard time refers to the total wind generated by the wind turbine, which is generally 11 to 15 m/s. If it can reach 2,000 standard hours per year, it is an area with rich wind resources.

The wind level is divided into 18 levels.

The wind scale (wind scale), called wind level, is a method of expressing wind intensity. Wind force refers to the force exerted by wind blowing on an object. Generally, the wind force is divided into 13 levels according to the different phenomena caused.caused by wind blowing over objects on the ground or water surface. The minimum is level 0 and the maximum is level 12. Winds at level 12 are particularly dangerous.

According to the national standards released by China in June 2012, based on the wind speed at a height of 10 meters at the standard weather observation site, the wind power level is divided into 18 levels. The commonly used units for expressing wind speed are nautical miles per hour, meters per second and kilometers per hour, respectively. The commonly used units for typhoon forecasting in China are meters per second. Wind is an important resource.

Advantages of wind energy

1. Environmental protection: Wind energy is a renewable and clean energy that does not produce pollutants or emit greenhouse gases. and has a low impact on the environment. CompCompared to traditional electricity production based on fossil fuels, wind energy is more environmentally friendly.

2. Energy Diversity: Wind energy is an abundant energy source that is not limited by geography or resources and can be widely used around the world. Wind energy can provide a diversified energy supply, reduce dependence on fossil fuels and improve energy security.

3. Economic Benefits: Wind power is an economically feasible source of energy. With the advancement of technology and the realization of economies of scale, the cost of wind energy has gradually decreased, becoming a competitive energy source. At the same time, wind energy can also generate jobs and tax revenue for the local economy.

4. Promote the development of renewable energies: Wind energyVienna is an important element in the development of renewable energies. By promoting wind energy, we can promote the research, development and application of renewable energy technologies and promote the transformation and upgrading of energy structure.
