Method and system for controlling communication power supply

The invention discloses a method for controlling a communication power supply and a system thereof. The method comprises the following steps: the criterion of the number of the current adjustment rectifier modules is obtained according to the current actual load and the best efficiency point of the communication power supply; the capacity of the power-on rectifier modules in the communication power supply is judged and whether the rectifier modules are in the criterion of the number of the adjustment rectifier modules or not is judged; if yes, the number of the power-on rectifier modules is adjusted; the system comprises an acquiring adjustment criterion unit and an adjustment unit. The acquiring adjustment criterion unit is used for acquiring the criterion of the number of the current adjustment rectifier modules according to the current actual load and the best efficiency point of the communication power supply; the adjustment unit is used for judging the capacity of the power-on rectifier modules in the co
