Embodiment 1

[0026] Embodiment 1, in the design of Jiangsu power grid, the screening and optimization method of the standardized design scheme of the substation to control the noise.

[0027] Jiangsu Provincial Electric Power Company conducted an exchange with Jiangsu Electric Power Design Institute (electric power major), Guodian Environmental Protection Research Institute (electric power environmental protection major) and other units on the status quo of substation noise in Jiangsu Province, and raised the problem. Jiangsu Electric Power Design Institute is responsible for providing the general layout diagram of each scheme, and Guodian Environmental Protection Research Institute is responsible for the calculation of noise and the arrangement of environmental protection measures.

[0028] Forecast calculation stage:

[0029] CadnaA calculation software is usually required in forecasting. This software is a noise prediction software developed by German datakustia company. CadnaA system...

Abstract

A method for screening and optimizing a substation standardized design scheme for controlling noise comprises: respectively designing power grid projects on the same voltage class to obtain a plurality of substation general layout typical design drawings; directly leading general layout diagrams, which are drawn in a CAD format, into each typical design drawing in an equal proportional manner in CandaA software; automatically generating two-dimensional coordinates; respectively carrying out prediction calculation on factory boundary environment noise emission of each scheme; summarizing schemes which cannot reach the emission standard requirement; respectively carrying out optimization design and increase of the measure of reducing noise on the schemes which cannot reach the emission standard requirement; carrying out prediction again; respectively carrying out calculation of an investment number on schemes which can be applied to a 2-class sound environment functional area; and screening the typical design drawing with the low investment number and using the screened typical design drawing as a selected scheme. According to the present invention, the projects can consider the environment protection factors on the feasibility study stage, the projects are avoided being greatly changed in the design process, the progress of the preliminary work of the power grid projects is greatly quickened, and cost of the preliminary work is saved.

Description

technical field [0001] The invention relates to a method for screening design schemes, in particular to a method for screening and optimizing noise-controlled substation standardized design schemes, which is directly applied to the field of electric power environmental protection. Background technique [0002] At present, the power transmission and transformation projects with a voltage level of 110kV and above invested and constructed by the State Grid Corporation of China and its subordinate units all adopt standardized design schemes. These designs are equipped with different modules, which can be adapted to different terrains, climatic conditions, and conveying capacity requirements. However, the standardized design module is more about saving investment and other factors, and does not add environmental protection factors in the feasibility study stage. [0003] According to the requirements of the "Environmental Impact Assessment Law of the People's Republic of China" ...
