摘 要:中压设备是列车上较大功率的设备,这些设备分散在列车各系统中,由辅助供电系统集中为其供电。由于电感效应,中压设备启动时的峰值电流会对辅助供电系统的安全性和稳定性产生不利影响。为保证列车辅助供电系统稳定、可靠运行,需要有效地控制中压设备启动时的峰值电流。基于列车控制与管理系统(TCMS,Train Control and Management System)的控制逻辑,研究列车上电自检阶段中压设备错时顺序启动控制方法,列车运行中空调压缩机错时启动控制方法,以及辅助供电系统故障工况下中压设备减载启动控制方法,避免中压负载峰值电流叠加对辅助供电系统造成的不良影响,确保在故障情况下有足够的辅助供电能力。通过实验室仿真测试和运营线上实车试验,初步验证了在辅助供电备用率和启动峰值电流的限制约束下,列车中压设备启动控制方法的有效性。Medium voltage devices are high-power devices on the train,which are dispersed in various systems of the train and powered by the train auxiliary power supply system.Due to the inductance effect,the peak current during the start-up of medium voltage devices may have adverse effects on the safety and stability of the train auxiliary power supply system.To ensure the stable and reliable operation of the train auxiliary power supply system,it is necessary to effectively control the peak current generated during the start-up of medium voltage devices.Aiming at avoiding the adverse effects of peak current superposition of medium voltage loads on the train auxiliary power supply system and ensuring sufficient auxiliary power supply capacity in case of faults,this paper study the sequential start-up control method for medium voltage devices during the power on self-test stage of a train,the start-up control method for air conditioning compressors during train operation,and the load reduction start-up control method for medium voltage devices under fault conditions in the auxiliary power supply system based on the control logic of the Train Control and Management System(TCMS).The effectiveness of the proposed train medium voltage devices start-up control method under the constraints of auxiliary power supply reserve rate and peak starting current was preliminarily verified through laboratory simulation testing and real train testing on an operating line.
