摘要
电动道路系统（ERS）是一项支持重型车辆（HGV）去碳化的新兴技术。电动道路牵引供电系统（TPSS）的可靠性是ERS规划和维护的关键考虑因素，但由于ERS的发展仍处于早期阶段，对不同ERS系统可靠性的研究尚不充分。本文填补了这一研究空白。本文首先利用失效模式和效应分析法（FMEA）分析了三种不同 ERS 系统的潜在运行风险。然后，建立故障树模型，分析三种 ERS 牵引供电系统的整体可靠性，找出薄弱环节。此外，结合牵引供电系统电气和非电气部件可能出现的故障，得出整体故障率和可靠性指标。最后，在分析潜在风险和相应可靠性指标的基础上，讨论了不同 ERS 解决方案的优缺点和未来发展前景。
Electrification of Urban Road Traffic: A Reliability Analysis of Traction Power Supply for Electric Road Systems
The electric road system (ERS) is an emerging technology to support decarbonisation of heavy good vehicles (HGVs). The reliability of the traction power supply system (TPSS) for an electric road is a key consideration in ERS planning and maintenance, but since the development of ERS is still at its early stage, the reliability study of different ERS systems has not been fully researched. This paper fills this research gap. It first analyses the potential operation risks of three different ERS systems using the failure mode and effect analysis (FMEA) method. Then, a fault tree model is built to analyse the overall reliability of the traction power supply system of each of the three ERS types and to identify the weak links. Furthermore, the overall failure rate and reliability indicators are obtained by combining the possible failures of both the electric and non- electric components of the TPSS. Finally, based on the analysis of the potential risks and the corresponding reliability indicators, the advantages and disadvantages of different ERS solutions and the future development prospects are discussed.
