N+1 redundant power system and method for achieving intelligent power consumption reduction thereof

Abstract

The invention discloses an N+1 redundant power system and a method for achieving intelligent power consumption reduction thereof. When the load is reduced, the method for achieving the intelligent power consumption reduction for the N+1 redundant power system comprises the following steps: judging whether the number of power modules in the normal mode is larger than one; when the number of the power modules in the normal mode is larger than one, detecting the total output power of the power system, and judging whether the total output power of the power system is smaller than or equal to a first preset value, wherein the total output power of the power system is the sum of power of the power modules in the normal mode, and the first preset value is related to the number of the power modules in the normal mode; when the total output power of the power system is smaller than or equal to the first preset value, switching one power module from the normal mode to the power consumption reduction mode. By means of the technical scheme of the system and the method, the complete machine power supply changeover efficiency of the power system can be raised.

Description

technical field [0001] The invention relates to the field of power supplies, in particular to an N+1 redundant power supply system and a method for realizing intelligent consumption reduction. Background technique [0002] The redundant power supply system is a power supply system composed of multiple power modules. Multiple power modules supply power to the electrical equipment. When a power module is abnormal, other power modules can continue to work without affecting the equipment. Normal operation, the operator then replaces the abnormal power module to restore the power supply system to normal. [0003] In a traditional redundant power supply system, all power modules start up after power-on and supply power to electrical equipment at the same time. However, the efficiency of each power module in the power system will vary due to different load conditions, such as figure 1 As shown, the efficiency drops significantly when the load is too small (<20%). Taking a 5+1 ...
