| 摘要: |
| 随着配电网用户侧异构电力物联设备(简称为“配电网用户侧物联设备”)接入电力系统，电力系统的安全防护边界变得日益模糊，使得基于物理隔离装置的安全防护体系无法成为保护电力系统运行安全的壁垒。考虑到设备的网络风险特征，配电网用户侧物联设备的网络安全给电力系统运行带来了新的隐患。为了更好地揭示电力系统在大规模配电网用户侧物联设备接入场景下所面临的安全威胁，并为制定相应的安全防护措施提供参考，对配电网用户侧物联设备的安全研究进行了全面的综述与展望。结合设备各组件间的通信架构，分析了目前配电网用户侧物联设备的网络安全脆弱性以及潜在的攻击手段；考虑配电网用户侧物联设备终端的运行特性，揭示其异常动作对电力系统造成的安全影响；从设备的“端”“管”“云” 3个方面重点综述了目前配电网用户侧物联设备各组件的主要安全防护研究；对该领域未来需要深入探索的研究方向进行了展望。 |

| Abstract: |
| With the distribution network user-side heterogeneous power Internet of Things devices(UPTDs) integrating into the power system, the security protection boundary of the power system becomes increasingly fuzzy, making the physical isolation devices-based security protection system unable to become a barrier to protect the operation safety of the power system. Considering the cyber risk characteristics of devices, the cyber security of distribution network UPTDs brings new hidden dangers to the operation of power system. In order to better reveal the security threats faced by the power system in the scenario of large-scale distribution network UPTDs access and provide reference for the development of corresponding security protection measures, the research on security of distribution network UPTDs is comprehensively reviewed and prospected. Combined with the communication architecture among the device components, the current cyber security vulnerability and potential attack means of the distribution network UPTDs are analyzed. Considering the operation characteristics of the terminals of the distribution network UPTDs, the safety impact of their abnormal actions on the power system is revealed. The main security protection researches of the distribution network UPTDs’ components are reviewed from three aspects of “terminal”,“channel” and “cloud”. The future research directions in this field are prospected. |
