Electrified Railway Traction Return Comprehensive Testing and Analysis System: Design, Development, and Validation

Finally, an electrified railway traction return comprehensive testing and analysis system was designed and developed, using LabVIEW software to achieve functions such as simultaneous collection, storage and analysis of multiple current and voltage signals. Field tests were conducted at multiple traction substations, and the results were analyzed to determine the distribution of traction return flow at each substation. The test results were also compared with simulation results to verify the accuracy of theoretical calculations and simulation models.
