Intelligent identification and prediction method of environmentally sensitive areas in power transmission and transformation projects

Abstract

The invention discloses an intelligent identification and prediction method for transmission and transformation project environmentally-sensitive regions. Access to a GIS is achieved through the spatial index technology, geographical location information of sensitive region targets is read, and space entity shapes of the sensitive region targets are determined; generated buffer region shapes are determined according to basic points, linearity judgment and break point concavity and convexity judgment are carried out through a vector algorithm, arcs are embedded, buffer regions are generated, and self-intersecting boundaries of buffer region boundaries are divided; the generated buffer regions are subjected to polygon cutting, regions of spatial data are re-divided, different data models in the regions are spatially overlapped, and automatic identification of the transmission and transformation project environmentally-sensitive regions is achieved; the identified sensitive regions are reflected in the GIS, an environmentally-sensitive region database is established, the environmentally-sensitive regions in the database are updated, and the change of the environmentally-sensitive regions is predicted in real time.

Description

technical field [0001] The invention relates to an intelligent identification and prediction method for an environmentally sensitive area of ​​a power transmission and transformation project. Background technique [0002] With the development of my country's electric power industry, the capacity of the power grid is getting larger and larger, the distance of transmission is getting farther and farther, the voltage level of transmission lines is also increasing, and the construction scale of high-voltage substations and overhead transmission lines is constantly expanding. Coupled with the influence of social factors such as economic development and population growth, it has become a general trend for new power transmission and transformation projects to gradually approach densely populated areas. In recent years, many cities have carried out the reconstruction and expansion of the power supply network. Substations have gradually been built from the suburbs to the urban areas....

AI Technical Summary

Problems solved by technology

[0003] Due to the large number of substations and transmission lines, relying solely on manual management of the environmental protection work of power transmission and transformation projects not only consumes a lot of energy and is prone to errors, so it is necessary to intelligently manage the environmental protection work of power transmission and transformation projects

At present, the State Grid Corporation of China has made great progress in the intelligentization of power grid environmental protection work, but there are still some problems in the actual work such as the low level of intelligence in some links, which restricts the efficiency of environmental protection work in power transmission and transformation projects.

[0004] In the stage of environmental impact assessment and design of power transmission and transformation projects, due to the lack of relevant data on the distribution of environmentally sensitive areas, in the process of site selection and construction of power transmission and transformation projects, the measures and management support measures adopted by some projects in terms of avoiding environmentally sensitive areas Insufficient; the environmental impact prediction technology of power transmission and transformation projects is not high in terms of automation and informatization, and cannot quickly, timely and accurately evaluate the impact of power transmission and transformation projects on environmentally sensitive points during the stage of site selection and route adjustment.
