Regional networked solar intelligent compensation street lamp system and its control method

Abstract

A regional networked solar intelligent compensation street lamp system, including a power supply priority selection controller, solar battery components, solar battery status acquisition sensors, power grid, photovoltaic grid-connected inverter, power supply module, voltage compensation controller, battery control device, battery pack, closed-loop current controller, small energy storage equipment and sensors attached to the solar LED lamp, and all solar LED lamps in the area; a control method of the street lamp system is also disclosed. The system adopts double closed-loop control in the core structure of power supply for LED street lamps, so that it can not only seamlessly connect to the mains compensation when the power of the solar cell components is insufficient, but also aim at the discontinuity, volatility and In emergencies, the power supply mode can be switched at any time, which can not only maximize the use of clean energy, but also ensure the smooth switching of power sources for the lighting system. In terms of power supply control, a closed-loop control method with multiple real-time feedback is adopted.

Description

technical field [0001] The invention relates to the technical field of solar street lamp mains power complementation and the field of LED lighting technology and networking, in particular to a regional networked solar intelligent compensation street lamp system and a control method thereof. Background technique [0002] The traditional street light control system uses a time control switch to control the street light switch at regular intervals, and the time needs to be manually adjusted as the season changes, which is extremely inconvenient to use. [0003] In order to solve the above problems, a solar street light control system has been developed in recent years. The solar street light control system uses solar energy as the energy source. During the day, the solar panel charges the battery, and at night the battery supplies power to the LED lights, which saves electricity and is very convenient. A good solution to the problems of the traditional street lamp control syste...

AI Technical Summary

Problems solved by technology

However, in this power supply control device of the prior art, in the process of switching between solar energy and mains power, the phenomenon of flashing lights (that is, short-term power failure) often occurs, and some even appear after the street lights are turned off at night, and the mains power turns off the battery. The phenomenon of being fully charged causes the solar energy to be unable to charge the battery during the day, resulting in energy waste

Therefore, the solar street lamp power supply control device in the prior art does not really realize the functions of solar energy priority and mains power supplement.
