降低极端暴雨对城市配电网风险的研究

Study on Reducing the Risk of Extreme Rainstorm to Urban Distribution Network

近年来,随着全球气候变化的不断加剧,极端灾害发生的频率和密度越来越大,如雷击、台风、冰灾、山火、暴雨等自然灾害对全球范围内电力系统的正常运行产生了严重影响,对电网形成了严重安全威胁,可能造成人员伤亡和财产损失,对国家安全和社会稳定产生重大影响。文章对暴雨对城市配电网的影响进行了分析;针对暴雨灾害,文中给出了应急抢险策略、城市电网评估策略,并对加强城市配电网防汛建设进行了讨论。包括加强防汛监测预警,提前完成电网评估、隐患排查、隐患治理,研究配网抢修物资储备与供应,加强城市配电管理体系机制建设,在灾害来临时,快速响应,做好应急抢险工作,对新建、既有电网设备设施进一步完善提升[1]。

In recent years,with the continuous intensification of global climate change,the frequency and density of extreme disastersare increasing,such as lightning strikes,typhoons,ice disasters,mountain fires,rainstorms and other natural disasters,which have a serious impact on the normal operation of power systems around the world,and pose a serious security threat to power grids,which may cause casualties and property losses,and have a significant impact on national security and social stability.The influence of rainstorm on urban distribution network is analyzed;In view of the rainstorm disaster,the emergency rescue strategy and the evaluation strategy of the urban power grid are given,and the strengthening of the flood prevention construction of the urban power distribution network is discussed.It includes strengthening flood control monitoring and early warning,completing power grid assessment,hidden danger investigation and hidden danger treatment in advance,studying the reserve and supply of distribution network emergency repair materials,strengthening the mechanism construction of urban power distribution management system,responding quickly when disasters come,doing a good job in emergency rescue,and further improving the equipment and facilities of new and existing power grids.
