A site selection method for power facilities considering the impact of storm and flood risks

Abstract

The invention discloses an electric power facility address selection method taking influences of rainstorm and flood risks into account. The method includes the steps that 1, basic information, aboutdefense against flood disasters, of an electric power facility is sorted; 2, factor analysis of the influence of the flood risk on the electric power facility is carried out, wherein a hydrologic andhydrodynamic model is utilized to conduct laminated simulation of flood inundation in the forward direction, disaster trigger factors having influences on the security of the electric power facility under meteorological rainfall conditions different in intensity are quantized, and then reverse disaster analysis is carried out to figure out a dynamic functioning process of the disaster trigger factors under different water inflow conditions triggered by different rainfall conditions; 3, selection of an optimal address for the electric power facility under the influences of the rainstorm and flood risks is achieved. By carrying out reverse laminated deduction on the disaster trigger factors from an actual disaster scene, the dynamic influences of the disaster trigger factors of rainstorm andflood on the electric power facility during a flood disaster are analyzed, the electric power facility address selection method is optimized in order to achieve effective risk control over other similarly important electric power facilities, and a decision support is offered to disaster prevention and reduction of the electric power facilities.

Description

technical field [0001] The invention relates to the field of disaster prevention and mitigation of electric facilities, in particular to a site selection method for electric facilities in consideration of the influence of storm and flood risks. Background technique [0002] In recent years, frequent earthquakes, heavy rainfall, typhoons, ice disasters and other extreme natural disasters have put forward higher and higher requirements for power grid security. As the basis of the power grid, power facilities are more susceptible to the direct impact of meteorological disasters. How to avoid flood disasters in the site selection of power facilities and minimize unnecessary losses caused by torrential rain and flood disasters is particularly important. At present, the factors considered in the site selection of power facilities are mainly basic conditions such as basic terrain, surface features, and the direction of the line network. The prevention of rainstorm and flood disast...

Problems solved by technology

At present, the factors considered in the site selection of power facilities are mainly basic conditions such as basic terrain, surface features, and the direction of the line network. The prevention of rainstorm and flood disasters is mostly guaranteed by the limitation of the spatial distance from the river network, and less consideration is given. According to the precipitation and flood evolution process, the influence of the surrounding environment on power facilities during the flood evolution cannot be eliminated
