Solar grid-connected control system capable of being monitored from remote used for street lamp

Abstract

The invention discloses a solar grid-connected control system capable of being monitored from remote used for street lamps. The system comprises a remote control terminal, a server, an integrated controller, and a plurality of grid-connected photovoltaic power generation devices. The integrated controller is connected with the server in a communication manner. The remote control terminal is connected with the server in a communication manner. The integrated controller is connected with the plurality of grid-connected photovoltaic power generation devices in a communication manner. Each grid-connected photovoltaic power generation device comprises solar cell panels, a grid-connected inverter, a lighting fitting, a transmission and distribution line, a power grid, and a lamp-post. The grid-connected inverter is integrated with a communication control function. The system monitors and manages the grid-connected photovoltaic power generation devices through remote control. In daytime, the grid-connected inverter converts direct current provided by the solar cell panels to stable alternating current, and generates power for the power grid through the transmission and distribution line. At night, electricity in the power grid is transmitted to the lighting fittings through the transmission and distribution line, realizing an illumination function of the lighting fittings.

Description

technical field [0001] The invention relates to the field of solar power generation, in particular to a remote-monitorable solar grid-connected power generation control system for street lamps. Background technique [0002] At present, the technology of using solar photovoltaic power generation has been widely used in road lighting, traffic signals, air-conditioning heating and other fields. electricity for its use. [0003] As the infrastructure of lighting, street lamps are distributed in every corner of the city. They are large in number, widely distributed, and generally unobstructed, which is very suitable for the application of photovoltaic power generation. However, if all of them are replaced with photovoltaic power generation, firstly, the power of the original light source is too large, the photovoltaic system cannot provide enough electric energy or the design of the original light pole is unable to carry too many facilities; secondly, a large number of batteries...

AI Technical Summary

Problems solved by technology

However, if all of them are replaced with photovoltaic power generation, firstly, the power of the original light source is too large, the photovoltaic system cannot provide enough electric energy or the design of the original light pole is unable to carry too many facilities; secondly, a large number of batteries are required, and the battery capacity is limited , low efficiency, short life and easy to cause pollution to the environment, high cost and difficulty in later maintenance

At the same time, street lights are distributed in every corner of the city or on remote highways. The working conditions or faults of these lights can only be known after arriving at the scene, which causes inconvenience in use or management.
