英文摘要： The electric traction system of electric locomotive is the power source of trains, and it is also the high risk area of locomotive fault. Its security and stability is important for the operation of railway. This project is going to research the fault diagnosis theory of electric traction system of electric locomotives, and try to achieve a practical breakthrough on fault diagnosis theory and application of locomotive electric traction system. Then a proper area divide method for distribute fault diagnosis of locomotive electric traction system will be proposed to solve many problems of the large-scale systems such as massive calculation problem, complex coupling relationship of parameters, bad real-time performance and so on. Several typical key devices will be chosen, the causes and state characteristic of their faults are to be analyzed so as to find out the suitable fault diagnosis method which fulfill their structure and characteristic. By doing this, fault model is no need to be precise, signal matches status easily, the resource of fault is less harder to be positioned, so the accuracy and reliability of fault diagnosis system for locomotive electric traction system can be advanced. Developing the train communication network to solve low efficiency of information sharing which is caused by different commu
