摘　　要：针对目前国内外并没有大功率整流系统的各部件损耗及效率的实时监测仪器或平台的现状,提出了一种基于光纤以太网通信的大功率整流系统能效测试新方法,并与传统的能效测试方法的同步测量机理、能效分析方法进行了综合比较.给出了一种直流大电流间接反演算法,并通过仿真和实验验证了算法的正确性和工程实用性.最后结合工程实践,对能效测试新方法的具体实施过程进行了详细的阐述.工程实例表明该能效测试方法可以有效实现工业整流系统各供电装备与系统的效率核算,并为提高其装备效率及系统节能提供必要的依据.Up to now there has been no special monitoring equipment or platform for the energy efficiency measurement of large power rectifier system. For this reason, a new method of energy efficiency measurement of large power rectifier system based on the fiber optic Ethernet communication was presented. In order to prove the advantages of the new method, this paper made a comprehensive and comparative study of the measuring principles, and the analytical method of energy efficiency. The method of indirect inversion of heavy direct current proves to be correct and can be well applied in practical projects through simulation and experiments. Finally, by combining with engineering practice, the specific implementation process of the new analytical method of energy efficiency was described. The project case indicates that the efficiency analytic method can correctly calculate the efficiency of the power-supply system of the industrial rectifier system, and can provide a proof of improving the efficiency of the equipments and saving the energy of the system.
