Problems solved by technology

However, because the above operations are controlled manually, they also have major disadvantages: since the load changes require human intervention to meet the needs, in the case of frequent load changes, the additional workload caused by human intervention will increase significantly

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the specific embodiments with reference to the accompanying drawings.

[0031] As shown in Figure 1, in order to realize energy saving of the system, the module sleep can be performed by turning off the AC input of the module. Therefore, the number of sleep modules needs to be determined for energy saving control. The energy-saving control method of the specific embodiment of the present invention adopts the following steps to determine the number of dormant modules:

[0032] 1) Set the number of rectifier modules of the power supply system corresponding to different loads;

[0033] 2) Monitor the load size, select the number of rectifier modules corresponding to the monitored load size according to the settings in step 1) and put it into use.

[0034] The size of the load can be determined by the size of the load current. In the software implementation of the method of the present inv...

Abstract

The invention discloses an energy-saving controlling method for a power-supply system and a device thereof. The method comprises the following steps: (1) setting the number of rectification modules of a power-supply system corresponding to different loads; and (2) monitoring the amount of the load and selecting the rectification modules to be used corresponding to the monitored amount of the load according to the setting in step (1). The device comprises a setting unit for setting the number of the rectification modules of the power-supply system corresponding to different loads; and a monitoring unit for monitoring the amount of the load and selecting the number of the rectification modules to be used corresponding to the monitored amount of the load according to the setting in the setting unit. The invention needs no extra workload, and has good energy-saving effect.

Description

technical field [0001] The invention relates to power supply technology, in particular to an energy-saving control method and device for a power supply system. Background technique [0002] Usually in the power system, such as the power system used in communication, the output capacity of the configured rectifier module is larger than the actual load. This is to ensure that there is enough capacity for battery charging, and on the other hand, it is also for future system expansion. Reserve modules for backup if needed. [0003] In the actual initial operation of the system, the load is generally small, which causes most modules to work in a light-load working state, and the output current of each rectifier module is only in the range of 10-20%. At this time, the working efficiency of the modules is relatively low , a serious waste of electric energy. Therefore, in the power system applied to communication, some power users manually withdraw the use of some rectifier module...
