Abstract
The invention discloses a method and a device for optimizing an inverter power supply system. The method comprises the following steps: acquiring working parameters of a load of the inverter power supply system; determining the quantity of functional units needing to enter a working state in the inverter power supply system according to the working parameters of the load, wherein the functional units are parts which are used for executing predetermined functions in the inverter power supply system. According to the method and the device, the problems in the prior art that as all functional modules in the inverter power supply system work when the load is a light load, resources are wasted and the working efficiency of the inverter power supply system is low are solved.
Description
technical field [0001] The invention relates to the field of electric power, in particular to a method and device for optimizing an inverter power supply system. Background technique [0002] Inverters are being more and more widely used in new energy distribution network access systems. figure 1 Shown is the existing parallel redundant inverter power supply system, such as figure 1 As shown, multiple modules work in parallel to meet the power supply requirements of the load. [0003] What needs to be explained here is that in the prior art, regardless of the working condition of the load, all the modules in all the inverters are used to work, and when the load is light-loaded, all the modules are allowed to work. The problem of low working efficiency of the inverter system. [0004] Aiming at the problem in the prior art that all the functional modules in the inverter power system work when the load is light load leads to waste of resources and low working efficiency of ...
