A distributed solar off-grid/grid-connected power supply street lamp system

Abstract

The invention provides a distributed solar grid separation / connection power source street lamp system which solves the problem that traditional solar street lamps can not be adjusted and controlled in a concentrated mode easily. A solar module power generation and storage system and a lighting system are controlled to work in a grid separation or connection mode by a grid separation / connection control system, the electric energy output end of a solar photovoltaic module is connected with the input end of an inverter, the output / input end of a charging / discharging controller in the inverter is connected with the input / output end of a storage battery matrix, the power output end of the inverter is respectively connected to the power input end of a master controller of a street lamp circuit, a two-way electric energy measuring meter, grid separation / connection circuit codes and street lamp circuit nodes, the master controller of the street lamp circuit is in communication with data of a GPRS public network, a plurality of street lamps are connected with the street lamp circuit nodes after being connected in parallel, the master controller of the street lamp circuit is respectively in communication with the multiple street lamps, and the inverter, the master controller of the street lamp circuit and the street lamp circuit nodes are all connected with a national power grid through the two-way electric energy measuring meter and the grid separation / connection circuit codes.

Description

technical field [0001] The invention relates to the technical field of solar lighting applications, in particular to the technical field of solar street lamp lighting, in particular to a distributed solar off-grid / grid-connected power supply street lamp system. Background technique [0002] Traditional solar street lamps mostly adopt a one-to-one control method, that is, a single solar street lamp is controlled by a single independent control system, and each independent control system includes a solar photovoltaic module 1, a controller 21, a battery 22, and a charging and discharging control system. Device 23, street lamp 24, see figure 1 , when there is sunlight in the daytime, the controller controls the charging and discharging controller to charge the battery with the electric energy generated by the solar module. At night, the solar module does not work, and the controller controls the charging and discharging controller to discharge and output the electric energy sto...
