| 电气化接触网采用单相工频、分相供电方式,供电臂、中性区等电信号的获取是确保列车自动过分相的基础。 针对传感
器绝缘老化等问题导致的电信号测量回路故障,提出地面自动过分相测量回路故障诊断及容错控制方法。 该法基于供电臂、中
性区等不同测量回路的机理分析,给出了基于回路信息相互校核的自动过分相测量回路故障诊断方法,并依据不同测量回路的
故障特征,构造了相应的容错控制方案。 最后,利用仿真和实际工程示范项目运行结果表明所提方法的有效性与可行性。

| 英文摘要: |
| The catenary is powered by single-phase industrial-frequency power dividing into multiple sections, the acquisition of power
feeder voltage, neutral-section voltage and other electrical signals are the foundation to ensure the train automatic-passing the neutralsection. Aiming at the fault of electrical signal measuring circuit caused by sensor insulation aging, the fault diagnosis and fault-tolerant
control method of ground automatic passing neutral-section’s measuring circuit is proposed. Based on the mechanism analysis of different
measuring circuits, such as power feeders and neutral-section, this method gives a fault diagnosis method based on the mutual check of
circuit information, and constructs the corresponding fault-tolerant control scheme according to the fault characteristics of different
measuring circuits. Finally, the results of simulation and practical project show the effectiveness and reliability of the proposed method. |
