What is the working principle of wind-solar complementary street lamp system?

A street lamp with complementary scenery, as its name implies, is a street lamp with complementary wind energy and light energy. It is the product of the further development of solar street lamps, which absorbs wind energy and light energy through fans and solar panels and converts them into electric energy. Wind-solar hybrid street lamp system can be used as an independent power supply system to provide electricity. The design of wind-solar hybrid street lamp should consider the factors such as the stability of fan operation, the weight of fan, the configuration of power supply system, the strength of lamp post and so on. Let's take a look at the street lamps with complementary scenery! 1. What is a street lamp with complementary scenery?

Wind-solar hybrid street lamp is a new type of energy-saving street lamp, which consists of solar panels, wind generators, wind-solar hybrid street lamp controllers, storage batteries and LED light sources. The solar cell array and the wind generator are used to store the generated electric energy in the storage battery. When the user needs electricity, the inverter converts the DC stored in the storage battery into alternating current, which is transmitted to the user's load through the transmission line, which not only reduces the dependence of urban lighting on conventional power, but also provides a new solution for rural lighting.

2. What is the working principle of the wind-solar hybrid street lamp system?

Wind-solar hybrid power generation system is a device that converts wind energy and light energy into electric energy. The working principle of wind-light complementary street lamp is to use natural wind as power, and the wind wheel absorbs the energy of wind to drive the wind generator to rotate, thus converting wind energy into electric energy. After the AC power is rectified and stabilized by the controller, it is converted into DC power to charge and store the battery.

Solar panels use monocrystalline silicon solar panels with the highest conversion rate at present, and directly convert solar energy into direct current through photovoltaic effect. When the wind energy resource is insufficient, it can be used by the load or stored in the storage battery for standby.

The core of the wind-solar complementary system is that wind energy and light energy complement each other to form a set of power supply system that can operate independently.

Three, wind complementary street lamp design considerations

1, the choice of norm

Fan is the landmark product of street lamp with complementary scenery. In the design and selection of fan, the most important thing is to require the fan to run smoothly. Because the light pole of the wind and scenery complementary street lamp is a cable tower without position, we should pay special attention to the looseness of the lampshade and the fixing parts of the solar bracket caused by the vibration of the fan when it is running. Another main factor in choosing a fan is its beautiful shape and light weight, which reduces the load on the tower.

2. Optimal configuration design of power supply system

Ensuring the lighting time of street lamps is an important indicator of street lamps. As an independent power supply system, wind-solar hybrid street lamp has an optimal configuration design problem from the selection of street lamp light source to the capacity configuration of fan, solar cell and energy storage system. It is necessary to design the optimal capacity configuration of the system according to the natural resource conditions of the street lamp installation site.

3. The intensity design of light pole

According to the capacity and installation height requirements of the selected fans and solar cells, the light pole strength design is carried out in combination with local natural resources conditions, and the reasonable light pole and structure form are determined.
