Problems solved by technology

However, solar energy and wind energy also have some disadvantages: (1) Whether it is wind energy or solar energy, its energy density is low. If only wind energy or solar energy is used to supply power to power supply equipment, there will be insufficient power, which brings difficulties to popularization and utilization.
(2) No matter wind energy or solar energy, they all change with the change of weather and climate, and the stability of energy collection is poor

Embodiment 1

[0054] Such as figure 1 As shown, a complementary power supply device based on solar and wind power generation, including solar panels installed continuously on the guardrails on both sides of the highway and wind turbines installed at intervals around the highway.

[0055] Such as figure 2 As shown, the solar cell panels are continuously installed on the guardrail through the panel fixing device; The fasteners are fixed on both sides of the guardrail, and the solar panel is fixed on the mounting plate through the fasteners. In this embodiment, fixing holes are provided at the four corners of the fixing plate and the mounting plate, and at the second turning point of the mounting plate, and the bolts pass through the fixing holes and are fixed by nuts. A fixing piece is arranged on the bottom surface of the solar battery panel, and fixing holes are arranged on the fixing piece and the mounting plate, and are fixed by bolts and nuts.

[0056] The mounting plate and the fixe...

Embodiment 2

[0080] Such as Figure 14As shown, a control method for complementary power supply for highway electrical equipment, the control method of the power supply device, the specific steps are as follows:

[0081] Step 1: The system is turned on, and all relays are disconnected;

[0082] Step 2: The microcontroller controls the power detection circuit to detect whether the remaining power of the battery is sufficient. If it is sufficient, go to step 3; if not, go to step 4;

[0083] Step 3: Close DC relay 1, DC relay 2 and DC relay 3, disconnect AC relay 1 and AC relay 2, supply battery power, and turn to step 2 for cycle detection;

[0084] Step 4: The microcontroller controls the voltage detection circuit to detect whether the mains circuit is normal. If the voltage is normal, go to step 5, otherwise go to step 2 to enter the cycle detection;

[0085] Step 5: Close AC relay 1 and AC relay 2, disconnect DC relay 2 and DC relay 3, supply mains power, and turn to step 2 to enter cy...

Abstract

The invention discloses a complementary power supply device based on solar and wind power generation, which includes a solar panel and a wind generator installed on a highway or around the highway, and the solar panel and the wind generator are connected with a storage battery for storing electric energy; The storage battery and mains supply power for the electrical equipment installed on the expressway through the power switching device; the dual power conversion device is directly connected to the DC electrical appliance, and is connected to the AC electrical appliance through the wireless power supply device. , to provide power for electrical appliances. The invention collects the electric energy converted from solar energy and wind energy to supply power to the storage battery, which can generate electricity efficiently, and is clean, environmentally friendly and pollution-free; at the same time, the battery power supply and the mains power supply are complementary, the battery power supply is the main power supply, and the mains power supply is supplemented. Save electricity to a certain extent.

Description

technical field [0001] The invention relates to the technical field of traffic power supply, in particular to a complementary power supply device based on solar and wind power generation and a control method thereof. Background technique [0002] With the rapid development of my country's economy, the construction of highway tunnels is increasing day by day. In order to ensure the safe operation of the highway, variable information boards, cameras, weather stations and other electrical equipment are installed along the highway. However, the long distance and large span of the expressway make the electrical equipment on the expressway consume a lot of electric energy, resulting in a large amount of energy consumption and increasing the operation and maintenance cost of the expressway. [0003] A large number of areas passing by the expressway are open, and wind and solar energy are sufficient. If they can be well utilized to provide power for equipment on the expressway, a la...
