摘要(Abstract)：

在新型电力系统构建和城市安全风险日益严峻的双重背景下，保障城市供电安全成为维护城市安全的首要任务。首先，分析了新型电力系统背景下城市电网面临的风险，梳理了近年来国内外发生的重大城市供电安全事故，分析了各次事故的原因。然后，提出了风险传导链的概念，并基于所提风险链演进与传导理论，针对近年来国内外发生的重大城市供电安全事故进行推演，制定风险阻断细化方案，提出电网风险评估流程及风险阻断推演框架。最后，提出城市供电安全水平提升的主要举措和工作建议。所提的风险传导链及风险阻断措施对于构建新型电力系统过程中夯实城市供电安全具有重要的现实意义。
In the context of new power system construction and the increasingly severe risks of urban security,urban power supply security has now become a top priority of urban security. Firstly,the risks faced by urban power grid in the context of new power system are analyzed. Then,major urban power supply accidents at home and abroad in recent years are sorted out,and the causes of each accident are analyzed. Then,the concept of risk transmission chain is put forward. Based on the evolution and conduction theory of the proposed risk chain,major urban power supply accidents at home and abroad in recent years are deduced,a detailed risk blocking scheme is formulated,and the grid risk assessment process and risk blocking deduction framework are put forward. Finally,the main measures and suggestions for improving the safety level of urban power supply are put forward. The proposed risk transmission chain and risk blocking measures have practical significance for consolidating urban power supply security in building a new power system.
