Power transmission and transformation project noise environment prediction method based on automatic recognition of environment sensitive target

Abstract

The invention discloses a power transmission and transformation project noise environment prediction method based on automatic recognition of an environment sensitive target. The method includes: reading geographic information corresponding to a power transmission and transformation project, and determining the shape of a generated buffering area according to a given spatial entity; utilizing a vector algorithm for linear judgment and salient point concavity and convexity judgment, embedding a circular arc to generate a buffering area, and dividing a self-intersecting boundary of a buffering area boundary; polygonally cutting the generated buffering area, re-dividing an area of spatial data, spatially stacking different data models in the area, and determining an environment sensitive area according to a stacking result; calculating maximum electric field intensity on the surfaces of leads, calculating sound power generated by each lead in heavy rain and sound energy generated by each phase at a position distant from a circuit according to number of divided leads and diameter of sub leads, stacking the sound energy of each phase, and converting into sound pressure level.

Description

technical field [0001] The invention relates to a method for predicting the noise environment of power transmission and transformation projects based on automatic identification of environment sensitive targets. Background technique [0002] With the development of society, the line corridors are increasingly tense, and the environmental impact of power transmission and transformation projects has become an important factor that must be considered in the process of project planning, feasibility study, design, construction and operation. With the rapid development of urban and rural construction and the continuous expansion of city scale, how to coordinate the relationship between power transmission and transformation projects, nearby residential buildings, and various environmentally sensitive areas has become a priority issue in the planning and design of power transmission and transformation projects. [0003] In the current design of power transmission and transformation ...

AI Technical Summary

Problems solved by technology

In recent years, the number of power grid environmental complaints has been increasing, and incidents of people obstructing the construction of power transmission and transformation projects have occurred from time to time. This not only brings difficulties to the construction of the power grid, but also seriously affects the safe operation of the power grid. many problems and stress

In addition, due to the low degree of automation and informatization of the environmental impact prediction of power transmission and transformation projects, the environmental impact prediction results of the project on sensitive points cannot be reflected in time during the stage of site selection and line selection, resulting in the guiding role of the prediction results for site selection and line selection. limited, which affects the quality and efficiency of site selection and line selection to a certain extent, and may also adversely affect the work of project environmental impact assessment, water conservation plan, environmental protection acceptance, and water conservation acceptance
