Hybrid power supply and energy storage system for communication base station

Abstract

The invention discloses a hybrid power supply and energy storage system for a communication base station. In a background condition with available mains supply, a wind power generator, a photovoltaic module, a fuel oil generator and a storage battery are also equipped, and a wind-solar photovoltaic hybrid controller, an inverter, an automatic switch and a rectifier module are correspondingly configured between the power supply devices and a DC load and an AC load. The photovoltaic module and the wind power generator are together connected with the wind-solar photovoltaic hybrid controller, and the wind-solar photovoltaic hybrid controller is respectively connected with the storage battery, the rectifier module, the DC load and the inverter. The mains supply and the fuel oil generator are connected with the input end of the rectifier module via the automatic switch. One end of the inverter is directly connected with the wind-solar photovoltaic hybrid controller and the other end is connected with the AC load. Multiple kinds of power supply devices are integrated, the complementarity is strong, the intelligent degree is high, and uninterrupted power can be provided for the matched communication base station.

Description

technical field [0001] The invention relates to a power supply system. Specifically, the invention relates to a power supply system for a communication base station, especially a hybrid power supply and energy storage system for a communication base station. Background technique [0002] The power system is an essential part of the operation of the communication base station. Most of the scattered communication base stations are built in remote places such as outside the city, on both sides of the road, on farmland and on the top of the mountain. Due to the inconvenient transportation, the daily maintenance is difficult and the timeliness is poor. Therefore, when designing a communication base station, it is important to consider the power supply reliability of the supporting power supply system. It is necessary to ensure sufficient capacity of power supply and to have a continuous and stable power supply method. Today, the commercially available power supply systems for co...
