A Study on Outlet Schemes of Indoor Substation based on AGA-AHP Algorithms

摘要

With the limited urban land resources and people's high demand for living environment, the construction of urban substation is being increasingly denser and miniaturized indoor substation is being widely used. The outlet of substation is closely related to land area, so this paper proposes a new outlet scheme named positive and negative triangle outlet, based on common ways of outlet, to reduce the land area of substation. In order to compare the advantages of this outlet scheme with that of other outlet schemes under different indicators, AGA-AHP (Accelerating Genetic Algorithm Analytic Hierarchy Process) are used to perform quantitative evaluation for weight of various outlet schemes in electricity environmental protection, difficulty of installation, operation and maintenance, distribution cost, and land area, as well as its sub-indicators, and determine the optimal outlet scheme that meets the requirements. According to the actual situation of the project, outlet model of indoor substation is built by AGA-AHP algorithms, and judgment matrix is established by related experts. The algorithms can realize the quantification of qualitative indicators and the output of the optimal outlet scheme, so as to provide some reference to the construction of substation.
