Description

technical field [0001] The invention relates to the field of public transportation, in particular to a design method and device for a high-voltage system of a high-speed train. Background technique [0002] In the development of existing high-speed trains, when a vehicle manufacturer receives an order, it is necessary to manually decompose the technical indicators of the order into various component modules, such as power components, running components, or car body components. The component modules are then decomposed into subsystem modules. For example, the power component module is decomposed into traction subsystem modules, high-voltage subsystem modules and brake subsystem modules according to technical indicators. After that, the R&D departments corresponding to each module are based on corresponding technical indicators. Designers combine their own design experience to develop models that meet the requirements. [0003] However, the existing high-voltage system design...

Problems solved by technology

[0003] However, the existing high-voltage system design methods for power components of high-speed trains have the following defects. The high-voltage system research and development department will restart system research and development every time it receives a development task. Among them, it is necessary to repeat research and development. The research and development work will cause repeated work, which will waste a lot of manpower, time and capital costs, and the probability of error is high, which will delay the research and development progress

Therefore, the design and development efficiency of the existing high-voltage system for high-speed trains is low, and the probability of error is high, which cannot meet the needs of rapid design of high-speed trains
