Wind turbines are mainly divided into two categories: horizontal axis and vertical axis.

We mainly produce 100W~50KW vertical axis wind turbines.

Wind turbines are usually used in off-grid or on-grid systems.

Wind energy and solar energy as pure renewable green energy, more and more people pay attention to, the complementarities of the two in time and region make the wind-solar complementary power generation system has a good match in resources, wind-solar complementary power generation system is an independent power system with good resource conditions, and wind-solar complementary street light is a significant application of wind-solar complementary power generation system.

The wind-solar complementary street light system is to change the grid power supply of traditional street lights into a wind-solar complementary power generation system that converts wind and solar energy into electricity. The system structure block diagram is shown in the figure. The system consists of wind generator set, solar photovoltaic array, rectifier circuit, voltage regulator circuit, unloader and energy-saving street lamp.The overall working principle of the system is as follows: the three-phase AC from the wind generator set is rectified after the DC and the DC from the photovoltaic array is charged after the voltage regulation circuit, and the battery supplies power to energy-saving street lights.

From the perspective of power generation and consumption, the system mainly consists of four parts: power generation, power transformation control, power storage and power consumption. The power transfer is shown in the figure.

With the continuous improvement of China's road traffic network, some remote areas have also built roads, but the use of ordinary street lights in these areas requires the laying of special lines, which will consume a lot of manpower and material resources, so the characteristics of independent power supply of wind and solar complementary street lights are very suitable for use in these areas. The power supply of mobile communication base stations, the electricity consumption of remote mountain villages and the electricity consumption of border posts can all be solved by wind-solar complementary power generation technology, so the study of wind-solar complementary street lamps has wide significance.

The correct use of wind turbines is crucial for their normal operation and reliability. The following are the precautions to be taken when using wind turbines:

1. If the motor is found to be working abnormally, shaking or making abnormal sounds, it should be stopped for inspection.

2. When the fan rotates at high speed, do not stand or perform other work on the direction of the rotation plane of the wind turbine to prevent the blades from flying out and injuring people.

3. The battery should be kept dry and clean, and metal objects should not be placed on the battery pack to prevent short circuits.

4. Do not place the negative grounding of the electrical box and the single matched reverse order together to avoid short circuits. Use the reverse power supply according to the reverse power supply manual.

5. The tightener of the stay wire will automatically loosen when encountering strong winds. After adjustment, it can be locked with iron wire. After each strong wind, check if the stay wire is loose and promptly eliminate any looseness. (Upright pole must be vertical)

6. Wind turbines should be wired separately and not mixed with other lines. It is recommended to use DC power for lighting, and AC power output from inverters can be used for household appliances. (The inverter and inverter output lines cannot be connected in parallel, and the inverter output line cannot be connected to the mains.)

7.When wiring the electrical box, first connect the battery and then connect the output line of the generator. When disassembling, first disassemble the output line of the generator and then disconnect the wiring of the battery pack

8.The shutdown switch of the electrical box is usually in the starting position, and is used for temporary shutdown when the battery is fully charged or in defense against severe storms. Only the wind wheel is slowly running and unplugged to the shutdown position, and the switch is not allowed to be unplugged when rotating at high speed.

Overall, the proper use of wind turbines is essential to ensure equipment safety, improve performance and extend service life. This is also a key measure to ensure the reliable operation and efficient generation of wind power systems.
