Description

technical field

[0001] The invention relates to the technical field of computer simulation, in particular to a fault injection method and system applicable to simulating a fault in a high-speed train traction drive system. Background technique

[0002] The safe operation of high-speed trains is the most important issue in the operation and development of high-speed railways. The rapid development of my country's high-speed railway has formed a high-speed railway technology system with Chinese characteristics. The overall technical level and application level are world-leading. Safe operation brings serious safety hazards.

[0003] The high-speed train traction drive system consists of traction transformers, traction controllers, traction converters, traction motors, and on-board sensors. It is the heart (conversion) and brain (control) of high-speed trains. It is one of the key systems for high-speed train operation safety, and it is also one of the main sources of high-spe...
