关于电力系统极端外部灾害主动防御技术的评述

A Review on Active Defense Technology of Extreme ExternalDisasters in Power System

近年来台风、山火、覆冰、暴雨等极端外部灾害频发,对电力系统安全稳定运行构成了重大威胁。亟需实现对全网的态势感知、在线决策和一体化协同防控。文中基于“双碳”能源转型与新型电力系统建设的新形势,论述了电力系统极端外部灾害及其对电网影响的新特征;构建了基于决策信息流的电力系统极端外部灾害防御全过程体系;提出了将停电防线拓展至系统级与设备级的资源统筹;最后,对电力系统极端外部灾害主动防御技术的发展方向进行了展望。

In recent years,the frequent occurrence of extreme external disasters such as typhoons,mountain fires,ice cover and rainstorms has become a major threat to the safe and stable operation of power system.Network-wide situation awareness,online decision-making and integrated collaborative prevention and control are urgently needed.Based on the"double carbon"energy transformation and the new situation of power system construction,the new features of extreme external disasters and their impacts on power grid are described,the extreme external disaster prevention system based on information flow in decision-making process is constructed,and the resources planning is put forward to expand power line to the system level and equipment level.Finally,the development direction of active defense technology for extreme external disasters in power system is prospected.
