Embodiment Construction

[0024] Specific embodiments of the present invention will be described in further detail below based on the accompanying drawings. It should be understood that the description of the embodiments of the present invention here is not intended to limit the protection scope of the present invention.

[0025] Please refer to figure 1 According to the present invention, the peak-shaving and valley-filling power supply control method of the communication base station power consumption period includes the following steps:

[0026] Step S11: Determine whether the power grid is out of power, if yes, go to step S12, otherwise go to step S13;

[0027] Step S12: the base station power supply supplies power to the base station load;

[0028] Step S13: Detect the remaining power of the base station power supply, and send the detection result to a controller;

[0029] Step S14: Judging whether the current time is a power consumption valley period, if yes, go to step S15, otherwise go to st...

Abstract

The invention discloses a peak clipping and valley filling power supply control method for a communication base station in a power utilization period. The method comprises the following steps: S11, judging whether a power grid is powered off or not; S12, enabling a base station power supply to supply power to a base station load; S13, detecting the residual electric quantity of the base station power supply; S14, judging whether the current time is an electricity trough period or not; S15, enabling the power grid to supply power to the base station power supply until the electric quantity of the base station power supply is full; S16, judging whether the current time is a power utilization wave crest period or not; S17, enabling the base station power supply to supply power to the base station load, and controlling the bidirectional inverter to convert direct current of the base station power supply into alternating current and feed back the alternating current to the power grid; S18,judging whether the current time is an electricity utilization peak time period or not. Therefore, the base station power supply can realize peak clipping and valley filling of the power grid on the premise of ensuring normal operation of the base station load.

Description

technical field [0001] The invention relates to the technical field of communication base station power supplies, in particular to a control method for peak-shaving and valley-filling power supplies during power consumption periods of communication base stations. Background technique [0002] In order to ensure uninterrupted communication, in addition to the normal mains power supply, the base station also needs to be equipped with an emergency backup power supply to ensure that the base station can also work normally when the mains power supply is abnormal. [0003] The backup power supply of existing base stations is mainly lead-acid batteries. With the development of lithium batteries, the cost has dropped, and it has become possible to apply them to base stations. Compared with lead-acid batteries, lithium batteries are more environmentally friendly and have a longer service life. At the same capacity, lithium batteries occupy a smaller area and are lighter in weight. ...
