Photovoltaic energy-saving controller of communication base station

Abstract

The invention discloses a photovoltaic energy-saving controller of a communication base station. A fuse is connected with the input end of a junction device. The output end of the junction device is respectively connected with the input end of a breaker and an anti-thunder device. The output end of the anti-thunder device is connected to the ground. The output end of the breaker is connected with a drain of a field-effect tube through an anti-reversing diode. A source of the field-effect tube is connected with the input end of a relay. A grid of the field-effect tube is connected into a PWM port of a single chip microcomputer. A large-power capacitor is connected between the field-effect tube and the relay. The output end of the relay is connected with a direct-current bus. The metering device is connected into the output end of a controlling system. According to the photovoltaic energy-saving controller of the communication base station, use of commercial electricity is greatly reduced, thus, the effect of saving electricity is achieved. Impact on the direct-current bus by the controller is relieved as much as possible, the direct-current bus is stably supported, the output harmonic waves are small and the integral design of converging, controlling and metering is achieved.

Description

technical field [0001] The invention relates to a base station power supply system, in particular to a photovoltaic energy-saving controller for a communication base station. Background technique [0002] The base station is a public mobile communication base station, which is a form of radio station, and refers to a radio transceiver station that transmits information between mobile phone terminals through a mobile communication switching center in a certain radio coverage area. [0003] The base station needs power supply to provide operating energy. The common method is to use the power grid to provide AC power. However, the base stations are built in mountains, plains, and valleys. In many areas, it is difficult or too costly to supply power through the grid. Therefore, Some base stations use local power generation to provide energy, and choose clean energy such as solar energy to power the base station. Although it is not limited by the grid power supply and reduce...

AI Technical Summary

Problems solved by technology

Although it is not limited by the grid power supply and reduces the operating cost of the base station, in some areas that lack sunlight, such as the southern region during the rainy season and the northeastern region in winter, the single power generation method of solar power cannot obtain enough electricity. Therefore, it is difficult to popularize and apply this type of base station power supply system in a large area
