摘要: |
目前,由于台风和暴雨等强降雨极端天气而造成的暴雨灾害问题已呈频发之势,很多城市对气候变化带来的突发极端天气灾害仍缺乏防范措施。部分城市基础建设的防范标准已经跟不上历史气候的变化,如配网变电站和配电室等设施,较易在洪涝灾害中发生故障。基于水动力学原理,以降雨导致的有源淹没为基本假设,利用高分辨率的地理信息数据和基于FloodArea模型的GIS栅格分析技术,对台州地区由降雨造成的洪涝灾害进行淹没模拟计算。然后模拟不同降雨情景的淹没范围和水深。结合10 kV配网承灾体的信息分布情况,确定研究区域内配网设备不同致灾等级下的临界面雨量。 |

Abstract: |
Recently, there is an increasing number of incidents, indicating that cities are suffering more from extreme weather events like typhoon and rainstorm. However some cities are still lacking of the protection of severe weather due to the climate change. It seems that the standard of hazard protection may be inadequate with the change of climate in the future, facilities like low voltage substations and distribution equipment may have a higher chance to breakdown during flooding events. Based on hydrodynamic theory, rainfall is assumed to be the main source of flooding. High resolution geographic information data and GIS grid analyzing technology based on FloodArea model are applied to make flooding simulation and calculation for flood disaster caused by rainfall in Taizhou area. And then the flooding area and depth of water of different rainfall scenes are simulated. Finally, combined the information distribution of disaster-bearing bodies of 10 kV electric distribution network, the critical rainfall to distribution network equipment under different levels causing disaster is determined. |
