Solar direct-current power generation control method for communication base station

Abstract

The invention relates to a solar direct-current power generation control method for a communication base station. According to a technical scheme, a lightning protection system, a control system, and a detection system are arranged. The lightning protection system is connected in series to an input terminal of a photovoltaic power supply. The control system includes a power supply system control switch and a communication power supply current backflow prevention system. The detection system includes a photovoltaic power supply detection and control system consisting of a DC / DC control power supply, a communication voltage acquisition circuit, a photovoltaic voltage acquisition circuit, and a voltage comparison circuit. A collected communication power supply voltage, a collected photovoltaic voltage, a highest voltage threshold value of the communication power supply are compared and then a control signal is outputted to control turning on or off of a direct-current power supply relay, thereby realizing controlling. The method has the following beneficial effects: a solar direct-current grid-connected power supply problem of a communication base station is solved and thus direct-current grid connection of the solar power generation is realized; the commercial power consumption load of the base station is reduced; objectives of new energy utilization, energy conservation, and emission reduction are achieved; and the daily operation cost of the base station can be saved.

Description

technical field [0001] The invention relates to a communication base station power supply control device and method, in particular to a communication base station solar DC grid-connected power generation DC-DC special control device and method. Background technique [0002] In the communication system, most of the power supply system in the communication industry adopts the inverter power supply system of alternating current to direct current, and the power supply voltage used by communication equipment is generally limited to direct current within the range of 60v-40v. [0003] At present, there are three types of solar power supply methods for communication base stations, the first is an AC grid-connected photovoltaic system; the second is an off-grid photovoltaic system; the third is a solar power supply system combined with mains power. [0004] The solar off-grid system is a solar power generation system that uses batteries for energy storage and is separated from the g...

Problems solved by technology

[0007] In addition, the control equipment of the original solar communication base station power supply system is either a grid-connected inverter or an off-grid controller, which can only work in one working state, when there is mains power or when there is no mains power

The use of solar energy in the above methods is more restricted, energy utilization efficiency is low, and there is a lot of waste.
