Abstract

The utility model discloses a method for controlling a power-supply system and a device thereof, aiming at solving the problem of weak real-time performance of the power-supply system in the prior art. The method of the invention comprises: according to the current load current and the battery charge current value of the power-supply system, the current load factor of a rectifier module which is put into service is calculated by a computing module; when the load factor exceeds load factor range corresponding to the desired value of the operating efficiency in the power-supply system, the number of the rectifier modules which are put into service is determined by a determination module when the load factor of the rectifier modules is within the load factor range according to the load current and the battery charge current value; a control module controls the rectifier module to open and close, so as to lead the number of the rectifier modules which are put into service is the same as that of the calculated rectifier modules. By adopting the technical proposal of the invention, the number of the rectifier modules which are put into service can be regulated to be the number of the determined rectifier modules, and the power-supply system can work with better efficiency all the time, thus realizing the effect of saving energy and improving the real-time performance of energy-saving control.

Description

technical field [0001] The invention relates to the communication field, in particular to a power system control method and device. Background technique [0002] In the communication industry, with the rapid expansion of business scale, the space and energy of the computer room are more precious. The power supply is called the "heart" of the communication system. Durable power creates a reliable network. Communication power supply and power supporting equipment are important for the communication network. Their normal operation is the basis for the safe and reliable operation of the communication network. At present, the load rate of the high-frequency switching power supply system of the base station in the floating charge state is small, and most of the time is lower than 30%. The low load rate of the switching power supply not only affects the communication efficiency, but also leads to the waste of electric energy (generally , when the load rate of the rectifier module ...
