摘　　要：随着我国轨道交通电力牵引系统的快速发展与技术成熟,其可靠性评估与智能化监控技术逐渐引起关注,数字孪生是基于数据与机器学习对实际物理系统的虚拟刻画技术,可以实现对实际物理系统的行为特征模拟与参数监测,因此将数字孪生技术引入轨道交通电力牵引系统领域,可为其数字化、智能化监控与运维提供发展思路与技术手段。文章首先对数字孪生技术目前在电力牵引系统中的应用现状进行了综述,进而列举了电力牵引系统数字孪生构建过程中所需的关键技术及其发展情况——在电力牵引系统领域,数字孪生及其相关技术仍在理论研究阶段,只有针对部分子系统的探索性研究,尚未形成完善的系统建模与智能监控体系;最后,文章展望了数字孪生技术在电力牵引系统领域的工程化实现前景,探讨了其投入工程应用可能会面临的内部技术问题与外部客观挑战,旨在为后续技术研究与实践提供参考。With the rapid development and technological maturity of China's rail transit electric traction system,its reliability assessment and intelligent monitoring technology have gradually attracted attention.Digital twin,as a virtual characterization technique for actual physical systems based on data and machine learning,can simulate the behavioral characteristics and monitor parameters of actual physical systems.Therefore,introducing digital twin technology into the rail transit electric traction system field can provide development ideas and technical means for the digital and intelligent monitoring and operation&maintenance of these systems.This paper first provides an overview of the current application of digital twin technology in electric traction systems,and then lists the key technologies required in the construction process of digital twin in electric traction systems and the development of these technologies.In the electric traction system field,digital twin and related technologies are still in the theoretical research stage,with only exploratory research on some subsystems available,and the complete system modeling and intelligent monitoring system has not yet formed.Finally,this paper looks forward to the engineering implementation prospects of digital twin technology in the electric traction system field,and discusses the internal technical problems and external objective challenges it may face when applied in engineering,for providing a reference for the subsequent technical research and practice.
