摘要
我国是多自然灾害国家,极端天气下日益频发的多灾害给配电系统安全运行带来巨大威胁。新型配电系统建设背景下,配电网受灾对象范围拓展、致灾机理更加复杂、供电支撑多元化,多灾害地区配电网应具备对极端自然灾害的预防、感知、抵御、恢复等能力。以配电网为研究对象,阐述了多灾害地区概念及我国多灾害地区配电网地理分布情况,从多灾害地区配电网受灾机理与仿真技术、防灾规划设计技术、防灾运行与复电技术三个方面进行了详细梳理与讨论。在此基础上,从提升配电网长期本质防灾能力与满足短时应急供电需求的角度,总结多灾害地区配电网防灾能力提升技术的研究趋势,为建设新型配电系统、提升其防灾能力提供参考。
China is particularly susceptible to natural disasters.The frequent occurrence of natural disasters under extreme weather conditions poses a significant threat to the safe operation of distribution systems.In the construction of novel distribution systems,the scope of affected objects is expanded,disaster-causing mechanisms are complex,and power-supply support is diversified.Distribution networks in multiple superimposed disaster areas must be able to prevent,sense,resist,and recover from extreme natural disasters.This study considers distribution networks as the object,as well as expounds on the concept of multiple superimposed disaster areas and the geographical distribution of distribution networks in multiple superimposed disaster areas in China.Additionally,three aspects are discussed comprehensively:disaster mechanism and simulation technology of distribution networks in multiple disaster-superimposed areas,disaster-prevention planning and design technology,and disaster-prevention operation and power-restoration technology.To enhance long-term intrinsic disaster-prevention capabilities and satisfy the short-term emergency power-supply demands of distribution networks,technological research trends to improve the disaster-prevention capabilities of distribution networks in multiple superimposed disaster areas are summarized.References for the construction of novel distribution systems and the improvement of disaster-prevention capabilities are provided.
