翻译为英语：最后设计研制了电气化铁路牵引回流综合测试分析系统采用LabVIEW编写软件实现同时对多路电流、电压信号的采集、存储和分析等功能。在多个牵引变电所进行现场测试对其结果进行分析分析各变电所牵引回流分布状态。同时将测试结果与仿真计算结果进行对比验证理论计算与仿真模型的准确性。

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.
