Site optimization method for routes based on environmentally sensitive areas of power transmission and transformation projects

Abstract

The invention discloses a path station location optimizing method based on a sensitive area of a power transmission and transformation engineering environment. The method comprises the following steps: generating a basic point in a GIS (geological information system) according to an environment sensitive area target on the basis of geological information; determining the shape of a generated buffer area according to the basic point, carrying out linear judgment and break point concavity or convexity judgment by using a vector algorithm, embedding arcs, generating the buffer area, and dividing a self-intersection boundary of a boundary of the buffer area; carrying out polygon clipping on the generated buffer area, dividing a reason of space data again, carrying out spatial overlapping on different data models in the area, and determining an environment sensitive area according to an overlapping result; comparing a set path or station location rule with the determined environment sensitive area in an overlapping manner; if the path or station location rule and the environment sensitive area are overlapped, correcting the path or the station location rule. The sensitive area can be avoided ahead of time or corresponding environmental protection measures are taken, and potential environment risks of projects are reduced.

Description

technical field [0001] The invention relates to a route site optimization method based on a power transmission and transformation project environment-sensitive area. Background technique [0002] With the development of my country's power industry, the capacity of the power grid is getting larger and larger, the transmission distance is getting longer and farther, the voltage level of the transmission line is also increasing, and the construction scale of high-voltage substations and overhead transmission lines is constantly expanding. Coupled with the impact of social factors such as economic development and population growth, it has become a general trend for newly built 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 been gradually built from the suburbs to urban areas. High-voltage overhead transmission...

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.
