Abstract: In order to solve the high costs and long intervals of imported vehicle maintenance for Beijing subway, a research was conducted on the following aspects, performance boost of the key components in traction system, optimization design of the main circuit, integration design of the power module, seamlessly replacement, and so on. The design concept and technical characteristics of localization traction system were described. Also the technical difficulties and application problems encountered in the localization process were summarized and analyzed. A principle of the seamless replacement design was proposed. The dynamic performance and relevant parameters of the localization traction system were tested on the test line. The results indicate that the localization traction system, with reasonable structure, high integration and reliable performance, is able to achieve seamlessly replacement. And all performance parameters meet the requirements of the current vehicles, superior to the imported system. Achieving localization seamlessly replacement of traction system on the current vehicle has great economic and reference values.
