基于双端电气量的高速铁路故障测距方法研究
Study of fault location method of high-speed railway using two-terminal electrical quantities
摘要
Abstract
All paralleling AT power supply scheme has been widely used in high-speed railway in China due to lots of advantages. The fault location is the key problem in practical application and how to improve the accuracy of fault location has drawn more and more attention. Based on the segmented power supply technology for traction network, the fault location method of high-speed railway traction network using two-terminal electrical quantities was proposed in this paper. By virtue of the generalized method of symmetrical components, the sequence network model of traction network was established and the characteristics of short circuit impedance were analyzed. Furthermore, the impedance characteristic curves of AT traction network were presented and the process of fault location was illustrated. Simulation results indicate that the method proposed is efficient and has higher accuracy compared with the existing schemes, which can be used in traction network fault location for high speed railway.关键词
