Problems solved by technology

During project review, experts lack sufficient information and may not be able to make accurate judgments on the environmentally sensitive areas involved in the project, which will bring hidden dangers to the subsequent construction of the project and environmental protection acceptance after completion, and also affect the authority of project approval documents
In the site selection and construction stages of power transmission and transformation projects, such problems have led to insufficient measures for some projects to avoid environmentally sensitive areas; similarly, the management department also lacks effective support means for power transmission and transformation passing through environmentally sensitive areas. effective project management
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

Embodiment Construction

[0048] The present invention will be further described below in conjunction with the drawings and embodiments.

[0049] In order to realize the automatic identification function of environmentally sensitive areas, it is necessary to analyze two important aspects of buffer analysis and overlay analysis in spatial analysis. Buffer analysis refers to a belt-shaped area of ​​a certain width established around a certain geographic entity or space object in order to identify its proximity or influence. Overlay analysis is the operation of superimposing two or more layers of map elements to produce a new element layer. The result is to split the original elements to generate new elements. The new elements integrate the attributes of the original two or more layers.

[0050] Buffer analysis is one of the important and basic spatial operation functions of geographic information system. It is a band (buffer polygon) with a certain distance (buffer radius) around a given space entity (collec...

Abstract

The invention discloses a power transmission and transformation engineering project electromagnetic 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, determining the shape of a generated buffering area according to a given spatial entity, and utilizing a vector algorithm and a stacking method to determine an environment sensitive area; utilizing an image method to calculate equivalent charge on a power transmission line so as to calculate an electric field generated by the equivalent charge, utilizing an equivalent charge method to calculate intensity of a high-voltage power transmission line spatial working frequency electric field, and predicting a working frequency electric field of the determined environment sensitive area; according to quasi-static characteristics of electromagnetic performance under working frequency condition, applying an ampere's law to stack calculation results by vector, and calculating to acquire magnetic field strength around a lead and a prediction value of a working frequency magnetic field of the environment sensitive area. By the method, when the environment sensitive area of the power transmission and transmission project is modified or removed, electromagnetic environment parameters that the environment sensitive area of the power transmission and transformation project is about to face can be predicted for corresponding rectification to avoid disputes.

Description

Technical field [0001] The invention relates to an electromagnetic environment prediction method for power transmission and transformation projects based on automatic identification of environmentally sensitive targets. Background technique [0002] With the development of society, line corridors are becoming increasingly tight, 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 the scale of cities, how to coordinate the relationship between power transmission and transformation projects and nearby residential and various environmentally sensitive areas has become a priority issue that must be considered in the planning and design of power transmission and transformation projects. [0003] In the current design of power t...
