Distributed synchronization solar energy street lamp control system

Abstract

The invention discloses a distributed synchronization solar energy street lamp control system comprising a photovoltaic cell array, a centralized control system, a storage cell array and an inverter, wherein the photovoltaic cell array and the storage cell array are respectively connected with the centralized control system connected with the inverter; and the alternating current output end of the inverter is connected with a street lamp sequenced power supply installed on a road. The centralized control system comprises a sensor subsystem and a principal computer control center subsystem, wherein the sensor subsystem comprises a sunlight sensor for detecting the illumination intensity of the street lamp working condition; the principal computer control center subsystem is used for controlling the photovoltaic cell array to convert solar energy into electric energy so as to store the electric energy in the storage cell array according to a signal collected by the sensor subsystem whenthe illumination intensity detected by the sunlight sensor is more than a preset threshold; and otherwise, the storage cell array is controlled to discharge and supply power for the street lamp sequence by the inverter. The distributed synchronization solar energy street lamp control system can improve stability, has high utilization ratio of the photovoltaic cell and the storage cell, lowers application cost and strengthens maintainability.

Description

technical field [0001] The invention relates to a solar street lamp system and the field of detection and control thereof, in particular to a street lamp control system of a distributed photovoltaic microgrid. Background technique [0002] With the development of economy, energy shortage is a problem that every country in the world is facing. At the same time, as the most important available petrochemical energy materials such as coal, oil, natural gas, etc. are facing the danger of depletion, the problem of energy shortage is becoming more and more serious, and affects people's living standards. On the other hand, environmental pollution and climate warming caused by petrochemical energy can no longer be ignored, affecting the development and promotion of sustainable development, energy saving and environmental protection concepts, and are attracting more and more people's attention. Among the many new energy sources, solar energy has the advantages of clean and pollution-...
