Personally, I think it depends on where you are. If the wind is strong in a relatively remote place, the wind power generation efficiency will definitely be higher. But if the wind is not so strong on the continent, the efficiency of wind power generation will definitely be higher. Wind power generation may not be the same. It is not as good as thermal power generation, so I think it is relatively more reliable to choose thermal power generation.
At what wind speed is wind energy equipment most efficient, damage to equipment is minimal
The efficiency of electric vehicle motors is 70% at 90% and the efficiency of wind turbines is 30%-50%. Since the efficiency of electric vehicle motors and wind turbines are two different concepts, they cannot be compared simply.
1. Efficiency of vehicle enginesElectric ules: Electric vehicle motor efficiency refers to the ability of electric vehicle motors to convert electrical energy into mechanical energy, usually expressed as a percentage. The efficiency of electric vehicle motors depends on many factors, such as motor design, materials, rotational speed, load, etc. Generally speaking, the efficiency of electric vehicle motors is between 70% and 90%, and efficient electric vehicle motors can achieve an efficiency of more than 90%.
2. Wind Turbine Efficiency: Wind turbine efficiency refers to the wind turbine's ability to convert wind energy into electrical energy, usually expressed as a percentage. The efficiency of wind turbines is affected by many factors, such as wind wheel design, blade material, rotation speed, wind speed, etc. Generally speaking, thehe efficiency of wind turbines is between 30% and 50%, and efficient wind turbines can achieve an efficiency of more than 50%.
Efficiency has nothing to do with wind speed, and high efficiency can be achieved at low wind speeds. (The efficiency of mechanical parts is not taken into account)
According to energy conservation, the power of the wind turbine is related to the wind speed
According to aerodynamics and Bates limit theory, the wind energy utilization rate of the wind turbine The limit is 59%
Each wind turbine has an energy utilization rate fixed maximum wind turbine. This efficiency is related to the tip speed ratio of the wind turbine (the ratio between the tip speed of the blade and the current wind speed).
For example, an optimal tip speed ratio (i.e. the peak speed ratio when the highest wind energy utilization rate is reached) is 9. Windne has a rotor diameter of 100 m and a wind turbine speed of 12 rpm. It is most efficient at 3.14*100*12/60/9=7 m/s<. /p>
