Strive to provide users with an environmentally friendly, convenient and safe experience.
system introduction:
1. Low wind speed start-up, low wind speed power generation, corrosion resistance and typhoon resistance of wind turbines:
As a street lamp application type wind generator, it is not only necessary to ensure safety, aesthetics and practicability, the wind generator can start to rotate at a wind speed of 2.0 m/s, and start charging at a wind speed of 2.5 m/s. In addition, when applied in coastal areas, it can withstand up to 14 strong typhoons, so it must have a mechanical brake + electromagnetic brake dual-safety braking system. In order to prevent the corrosion of the air in coastal areas, the various parts of the wind turbine must be made of anti-corrosion materials.
2. Intelligent control of the control system (light control, time control, overcharge, overdischarge, overload, undervoltage, protection, etc.):
As a street lamp control system, it not only needs to realize light effect control but also needs time control, so as to achieve the purpose of intelligent automatic control. During the charge and discharge period, it is necessary not only to prevent excessive charging and discharging, but also to realize functions such as excessive discharging. In addition, a low-voltage boost charging system at the core of the control system, when the electric voltage generated by wind power generation and solar power generation is less than 24V and greater than 15V, boost this part of the electrical energy to more than 24V, so that it can be processed. Take advantage of.
3. The bearing, anti-typhoon and shape design of the supporting system:
Ordinary street lights have no load-bearing requirements on the top of the pole, but as a
wind-solar complementary street lamp, not only the weight of the 50kg wind turbine and the weight of the solar battery pack, but also the need for deflection resistance in the event of a typhoon. The fan is in strong wind. The process of low-speed rotation is an overall force-bearing surface. Therefore, considering the above factors, the strength and cross-sectional shape of the lamp pole must consider the above safety factors.
4. The selection of the instantaneous voltage and charging and discharging capacity of the energy storage system:
The energy storage batteries used in wind-solar hybrid solar street lights need to be continuously charged and discharged. Therefore, when choosing the battery, the main choice is to choose a floating-point voltage with a low instantaneous start voltage and a matching load power that can be repeatedly charged and discharged. 20-28V maintenance-free gel storage battery.
5. Solar power matching and conversion rate matching selection:
The photovoltaic modules used in wind-solar complementary street lamps are limited by the conditions of the application of light resources, and economic factors should be considered in the selection and ratio of power. No matter the solar cell modules made of monocrystalline silicon, polycrystalline silicon or amorphous silicon, they are meeting their requirements. The conversion rate is between 15% and 17% according to local conditions. When choosing installation, it is necessary to set different sun inclination angles according to the latitude of the installation site.
6. Integration and matching of low-voltage lighting fixtures:
The lighting fixtures of wind-solar complementary street lamps mainly choose low-voltage 24V lamps, such as energy-saving lamps, induction lamps,
LED Lamps, metal halide lamps, etc. The brightness of different combinations of these lamps can reach the effect of ordinary high-voltage lamps. A series of parameters such as illuminance and height need to meet the standards of street lamps. The power of the lamps must not only match the power generation of wind power equipment and solar power equipment, but also match the wind and solar resources of the place where they are used. And there is no danger of electric shock.
7. Integration of the above six major systems (reliability, matching, aesthetics, economy):
The integration of the above six major parts of "wind turbines, control systems, support systems, energy storage systems, solar power generation systems, and lighting systems" is not only the principle of l+1=2, but ultimately needs to reach 1+1= l requirements, any part of the mismatch will affect the change of the entire system. And because of the different conditions in different regions, different
wind-solar complementary system technologies are needed to adapt to regional changes, so as to achieve the most economical and most suitable system for users. The safety and reliability of the whole system is the first; the practicability is the second; the perfection of each component and the overall design is the third; the economy is the fourth. The integration of the six systems is ultimately used as a street lamp, and meeting the needs of users in different regions is the ultimate goal.

Advantages of wind and solar hybrid solar street lights
Wind-solar hybrid street lights use high-performance large-capacity maintenance-free lead-acid batteries to provide sufficient power for wind-solar hybrid street lights, ensure the lighting time of LED wind-solar hybrid street light sources in rainy days, and greatly improve the stability of the system. The main advantages are listed below:
Energy-saving, emission-reduction, and environmental protection; no large amount of electricity expenses in the later period; resource-saving and environment-friendly society is becoming the general trend. Compared with traditional street lamps, wind-solar hybrid street lamps use renewable solar and wind energy in nature as energy sources, do not consume any non-renewable energy, and do not emit polluting gases into the atmosphere, resulting in reduced pollution emissions to zero. In the long run, the protection of the environment is self-evident, and at the same time, the cost of a large amount of electricity expenses in the later period is eliminated.
The cable laying project is exempted, and there is no need to construct a large number of power supply facilities; the operation procedures of the mains lighting project are complicated, and the basic works such as cable trench excavation, laying concealed pipes, pipe threading, and backfilling require a lot of labor; at the same time, transformers, power distribution cabinets, and Large quantities of electrical equipment such as electrical panels also consume a lot of financial resources. Wind-solar hybrid street lamps do not. Each street lamp is a separate individual, no need to lay cables or large quantities of electrical equipment, which saves both manpower and money.
Individual damage does not affect the overall situation, and is not affected by large-scale power outages; because conventional street lights are connected by cables, it is likely to affect the entire power supply system due to individual problems; this situation will not occur with wind-solar hybrid lights. Distributed independent power generation system, individual damage will not affect the normal operation of other street lights, even in the event of a large-scale blackout, it will not affect the lighting, and uncontrollable losses are therefore greatly reduced.
Save a lot of cable costs, and avoid the loss of cable theft; installing street lights in remote areas where the power grid is not widely available, the cost of wire installation is high, and there will be serious theft. Once stolen, the entire power output will be affected and the loss will be huge. The use of wind-solar complementary street lamps will not have this concern. Each street lamp is independent, eliminating the need for cable connections. Even if theft occurs, it will not affect the normal operation of other street lamps and minimize the loss.
Intelligent control, free of manual operation, simple construction and convenient maintenance; wind and solar hybrid street lights are controlled by intelligent controllers, which can be divided into two automatic control methods: time control and light control, which are both safe and economical; independent and integrated power supply system , It is not interfered by large-area circuit construction, the process is simple, the construction period is short, and the maintenance is more convenient.
City lighting: As an emerging energy system, it has played a role in lighting while saving costs and improving system stability. Today, when traditional energy occupies most of the market, new energy has undoubtedly become a highlight of cities and communities.
Improve people's awareness of energy conservation; the lack of traditional energy sources and environmental pollution have reached the point where it must be resolved. The global air pollution is quite serious, and the use of new energy can effectively raise people's awareness of energy conservation and make our lives more quality and energy-saving.
Wind-solar hybrid street lights are smart street lights that use wind and solar energy for power supply. At the same time, they also have the advantages of both wind power and solar power, providing a stable power supply for urban street lights.
