Research on real-time measurement of key parameters of stray current in DC traction system

摘要：

In this paper, the measurement of track resistance and track-to-earth resistance in DC traction system was discussed, First-order differential equations is presented to solve the problem. The measurement only needs track-to earth voltages and track currents at 2 different points in tunnel, no needs to detect the train location. The use of communication ensures the simultaneity. Test data upload to the computer, and the real-time measurement of track resistance and track-to-earth resistance was performed on the regular run, which provides the reliable evidence to evaluate the stray current.
