Problems solved by technology

[0004] 1. All electricity is generated by fuel oil, which has a relatively high power generation cost
2. The generator set works continuously in turns for a long time, and the unit needs to be maintained regularly, so that the reliability of the communication base station equipment cannot be guaranteed
3. The synchronous generator set works at a fixed speed no matter it is no-load or full-load, and the engine fuel consumption cannot be optimally controlled.
4. Equipped with a charger of equal power, when 220V AC is converted into 48V DC, it will lose about 10% of the power
However, the device does not involve the use of other energy sources, such as wind energy, and there are certain limitations

Abstract

The invention relates to a combined DC power supply control system for a communication base station. A solar generator set is connected with a power supply management controller through communication lines. A discharging resistor is connected with a discharging switch K1. A wind powered generator set is connected with the power supply management controller through a transmission line. The power supply controller is connected with an internal combustion generator set through a communication line. The solar generator set and the wind powered generator set are connected with a bus connection bar respectively. The bus connection bar is connected with a storage battery and electric equipment respectively. The internal combustion generator set is connected with the bus connection bar. The system combines three power supply modes of the solar generator set, the wind powered generator set and the internal combustion generator set to achieve the optimal energy conservation and emission reduction effects. The system preferably adopts solar power generation and wind power generation and starts the internal combustion generator set only when the solar generator set and the wind powered generator set can not supply enough power, thereby reducing operation cost.

Description

technical field [0001] The invention relates to a hybrid DC power supply control system for a communication base station, in particular to a power supply device for a communication base station without mains power supply. Background technique [0002] In remote areas or mountainous areas, since the 220V public power grid has not been fully popularized, the communication base stations in this area are generally powered by internal combustion generators. The internal combustion generator set is generally a synchronous generator set with a speed of 1500 rpm and a voltage of 220V. The electrical equipment used by the communication base station is powered by a 48V DC battery pack, and an external charger of equal power is required to convert the AC of the synchronous generator set into a DC power supply to the battery pack. In order to improve the continuity of the power supply of the communication base station, a backup generator set is used for power supply, that is, two gener...
