Wind-solar hybrid street light is a street light system that uses wind power to generate electricity. It combines wind turbines with street lights, and uses the electricity generated by the wind turbine to power the street lights, achieving sustainable use of energy. When choosing the axial direction of a wind turbine, both the vertical axis and the horizontal axis have their own advantages and applicable scenarios.
First of all, vertical axis wind turbines have the following advantages:
1. Strong adaptability: Vertical axis wind turbines can work in a variety of wind directions and are not restricted by wind directions. This means it can work in complex urban environments, such as high-rise buildings, trees and other places that affect the wind direction.
2. Simple structure: The structure of the vertical axis wind turbine is relatively simple. Due to the symmetry of its design, it does not need to track the wind direction, so it can reduce the complexity and failure rate of mechanical components.
3. Good quietness: The blades of vertical axis wind turbines produce relatively little noise when rotating, which can reduce interference to the surrounding environment.
However, horizontal axis wind turbines also have their unique advantages:
1. High efficiency: The blades of horizontal axis wind turbines can be adjusted according to the wind direction to obtain the best Wind energy utilization efficiency. This gives horizontal axis wind turbines an advantage in wind energy conversion efficiency.
2. High stability: The structure of the horizontal axis wind turbine is relatively stable and can better resist the impact and changes of wind force. This makes horizontal axis wind turbines more reliable in adverse weather conditions.
3. Easy maintenance: The mechanical components of horizontal axis wind turbines are relatively easy to maintain and replace because they are usually located on the ground and do not require climbing for maintenance.
In summary, vertical axis and horizontal axis wind turbines have their own advantages in different scenarios. For wind-solar hybrid street light systems, if the environment around the street lights is complex and the wind direction is changeable, vertical axis wind turbines are more suitable; if the wind direction where the street lights are located is relatively stable and high wind energy utilization efficiency is required, horizontal axis wind turbines are more suitable. Therefore, when selecting the axial direction of a wind turbine, comprehensive considerations need to be made based on specific application scenarios and needs.
Should I choose a vertical or horizontal axis wind turbine for personal use? Which one is more practical?
1. Among all wind energy generators, the power generated by each rotation of the wind energy generator is different depending on the power of the wind energy generator. For example, the most common 2MW direct drive Type wind energy generator, when the wind energy is sufficient and stable, the wind motor can generate 2,000 degrees of electricity every 60 minutes, and it takes 3.5 seconds for the fan blades to rotate once, and 60 minutes is 3,600 seconds, so the generator takes 3.5 seconds to rotate once. The amount of electricity generated per second is 0.56 kilowatt-hours, so the electricity generated by the wind turbine fan for each rotation is 0.56×3.5 seconds, which is 1.94 kilowatt-hours.
2. According to the different rotation axes of wind energy generators, wind energy generators are divided into horizontal axis wind turbines.There are two types of generators, and vertical axis wind turbines. The principle of wind turbine power generation is actually very simple. The wind blows the huge blades of the wind energy generator to generate kinetic energy, which is then converted into electrical energy through the internal generator.
Wind turbines can be divided into horizontal axis and vertical axis according to the orientation of the fixed axis of the blades. When the horizontal-axis wind turbine is working, the direction of the rotating axis is consistent with the wind direction, and the direction of the vertical-axis wind turbine's rotating axis is at right angles to the wind direction.
Horizontal-axis wind turbines usually need to constantly change direction to keep in line with the wind direction. Vertical axis wind turbines do not have to do this because they can collect wind energy from different directions. Horizontal axis wind turbines occupy a mainstream position in the world.
It is recommended to use a horizontal axis wind turbine
