Starting wind speed generally refers to the wind speed that needs to reach a certain value to start the wind turbine; while working wind speed generally refers to the wind speed that the wind turbine needs to reach to start generating electricity.
01 Start wind speed
The wind speed needs to reach a certain value to start the wind turbine. For small wind turbines, the starting wind speed is generally 2 to 3 meters per second. The minimum wind speed for a wind turbine to start generating electricity, i.e. the starting wind speed, is usually between 5 and 9 meters per second. This means that even if the wind turbine has started and started to rotate, it will still not start generating electricity if the wind speed does not reach the starting wind speed.
02 Working wind speed
Generally speaking, the optimal operating wind speed for a wind turbine is the range in which it can generate the maximum output power. This range is usually between 8 and 12 meters per second, at which the generator is most efficient and can effectively convert wind energy into electrical energy.
In addition, the maximum operating wind speed of a wind turbine also needs to be considered. When the wind speed exceeds a certain value, in order to protect the safety of the equipment, the wind turbine may take control measures, such as adjusting the blade angle or stopping operation.
03 The impact of wind speed on wind turbines
01 Low wind speed environment
In low wind speed environment, wind turbines may not start or capture enough wind energy to generate electricity. This will cause the output power of the generator to decrease or even fail to work properly.
02 Medium wind speed environment
In a moderate wind speed environment, wind turbines can efficiently capture and convert wind energy. At this time, the output power of the generator reaches the maximum, which can provide users with a stable supply of electricity.
03 High wind speed environment
In high wind speed environment, wind turbines may be affected by excessive load, resulting in equipment damage or failure. Therefore, when the maximum operating wind speed is reached or exceeded, the wind turbine will automatically stop working to protect the safety of the equipment.
In summary, the start-up and operating wind speed of wind turbines are key factors to ensure their normal operation and efficient output. Understanding and mastering these wind speed conditions is of great significance to optimizing the performance of wind turbines and improving energy efficiency.
