摘　　要：为准确测量、分析牵引系统能效,文章以电动车组牵引系统为研究对象,结合IEC 62888-2:2018的电能测试要求和GB/T 25117.1—2010的转矩、转速测量仪要求开发了电动车组牵引系统能效测量系统。为提高测量准确度文章设计了一种能实现电参数、机械参数同步采集的方案,其采用特制的带隔离功能的高压采集板卡直接采集27.5 kV互感器输出电压信号,并采用脉冲型输出转矩、转速传感器测量牵引电机机械参数。标准信号源验证试验结果显示,能耗的测量准确度优于标准要求的1.5%,机械参数测量转矩精度优于标准要求的0.5%,转速精度优于标准要求的0.1%。同时,为了验证系统在动态能耗测量中的准确性,采用高精度功率分析仪与该测量系统同时测量同一线路数据的牵引系统能耗,其相对误差小于1%。In order to accurately measure and analyze energy efficiency of traction systems,especially in the current absence of relevant standard references,this article presents an energy efficiency measurement system developed based on the requirements of IEC 62888-2:2018 for electric energy testing and GB/T 25117.1-2010 for torque and speed measuring instruments,taking the traction system of electric multiple units(EMUs)as the research object.To improve measurement accuracy,a purpose-made highvoltage acquisition board with isolation is designed to directly collect the output voltage signal of the 27.5 kV transformer and a pulse-type output torque-speed sensor to measure the mechanical parameters of the traction motor,enabling synchronous collection of both electrical and mechanical parameters.Through experiments conducted with standard signal sources,it is verified that the measurement accuracy of system energy consumption surpasses the standard requirement by 1.5%.Furthermore,regarding measurement of mechanical parameters,the torque accuracy exceeds the standard requirement by 0.5%,while the speed accuracy surpasses it by 0.1%.Meanwhile,in order to verify the system accuracy in dynamic energy consumption measurement,a highprecision power analyzer and this measurement system were used to simultaneously measure the energy consumption of the traction system with the same track data,revealing a relative error of less than 1%.
