- W4315777701 abstract "The flexible traction power supply system based on power electronic device can cancel the electrical phase separation of the existing railway, which can bring many direct and indirect economic benefits to the railway. This paper takes flexible traction power supply system as the research background, and takes its core equipment -- electronic traction transformer as the research object. Firstly, this paper studies the topological structure and control mode of three-level three-phase to single-phase cascaded converter. Under the scheme of 1700V, 3300V and 4500V voltage class level IGBT, the system parameters and the number of cascaded modules are designed, and the simulation model of the system is built in Matlab/Simulink. The reliability analysis method of device level - module level - system level and the average fault-free working time for electronic traction transformer are studied. The investment cost of electronic traction substation is studied, and the reliability - cost benefit comparison analysis of three schemes is made. The recommended system switch tube and module number selection are given. In this paper, the economic analysis of electronic traction transformer used in flexible traction power supply system is carried out, which can provide the basis for the engineering popularization of the system." @default.
