Modeling analysis of high speed railway traction return current system
摘要
Abstract
The distribution of high speed railway traction return current is complex. It is necessary to carry out its accurate analysis of the model. Based on the parallel multi-conductor transmission line theory, this paper sets up a unified mathematical model of the traction network and realizes the impedance calculation for different forms of traction network. With the method of buried bare wires, the modeling of integrated grounding wire makes up for the shortcomings of grounding resistance equivalent method which cannot calculate wire current, and takes the coupling between the integrated grounding wire and the other wire into account. The distribution proportion of current in different return wires is figured out and compared with the measured return current ratio. In this way, the accuracy of the buried bare wires method and the chain network flow algorithm are verified. The return current test schemes are explored.关键词
