Embodiment Construction

[0029] The invention is applicable to site selection and design flood level analysis of power engineering in any area. The present invention will be explained below by taking the Baodong 500kV substation project planned to be built near Baoding City in the south of Hebei Province as an example.

[0030] First, analyze the topography of southern Hebei Province. In the southern part of Hebei Province, there are Daqing River and Ziya River in the Haihe River Basin. The Daqing River is located in the middle of the Haihe River Basin, with Taihang Mountain in the west and Bohai Bay in the east. It is located between Yongding River and Ziya River. , the basin area is 43060km 2 , the watershed spans Shanxi, Hebei, Beijing and Tianjin 4 provinces and cities, and the area of ​​Hebei Province is 34683km 2 , accounting for 80% of the total basin area; Baoding City covers an area of ​​21,933km 2 , accounting for 51% of the total drainage area. The Ziya River Basin is located in the sout...

Abstract

The invention discloses a two-dimensional unsteady-flow numerical model based power engineering location method. On the basis of a plurality of site locations primarily selected according to design requirements of a power grid transmission line, the two-dimensional unsteady-flow numerical model is subjected to verification, parameter modification and design flood simulation by determining a simulation area, digitizing the simulation area and establishing the two-dimensional unsteady-flow numerical model and historical flood data, the site locations primarily selected are sorted according to largest submerged depth, and a primary selection sequence of the site locations is obtained. By the two-dimensional unsteady-flow numerical module flood routing technology, hydrologic characteristics in a certain area and flood hydraulic elements during simulation of flood routing can be truly and objectively reflected, flood control safety of electric power engineering can be guaranteed, construction accuracy can be improved, land source consumption can be reduced, and construction cost can be lowered.

Description

technical field [0001] The invention relates to a method for selecting a site for an electric power project, in particular to a method for selecting a site for an electric power project in a plain area through numerical simulation. Background technique [0002] At present, my country's land resources are in short supply. Due to the limitation of land resources, the project sites of power planning and construction have to be selected in low-lying areas such as flood detention areas, flood discharge areas, and floodplain areas. On the other hand, electric power projects have certain fortification requirements for floods, and the design flood level directly affects the safety and construction investment of the power project. The large amount of construction work may even affect agricultural production and cause unnecessary social conflicts; if the design flood level is low, it will cause huge losses to the power sector and nearby production units in the event of a flood. It is...
