摘要
铁路牵引供电系统低频网压波动会造成列车无法正常取流,严重时会造成列车牵引系统闭锁。本文通过对牵引供电系统实测数据、系统阻抗等值模型及Middlebrook判据进行分析研究,提出了抑制牵引供电系统低频网压波动的方法,为铁路安全运营及牵引供电系统工程设计提供重要依据。
The low frequency network of railway traction power supply system may induce train＇s abnormal current collection, and may cause the locking of train traction system. On the basis of analysis and researches of tested data of traction power supply system, system impedance equivalent model and Middlebrook criterion, the paper puts forward the method for compression of low frequency network voltage fluctuation of traction power supply system, providing important basis for railway safety operation and design of traction power supply engineering.
