Research on Spatial Siting of Transmission and Substation

Objective: Based on borehole survey data from 13 designated research areas in Muyang County, Suqian City, Jiangsu Province, and considering various influencing factors such as climate conditions, topography, geological characteristics, hydrogeology, and seismic activity, a study is conducted using the analytic hierarchy process (AHP) to determine the optimal location for the construction of a substation. Methods: Initially, a hierarchical structural model is established. Subsequently, experts rate various influencing factors using a 9-level scale and create judgment matrices. Finally, the weights of these influencing factors are calculated using the arithmetic mean method. Results: Combining the weights obtained through AHP with the scoring table for each location results in the final ranking of site scores. The location with the lowest score indicates that it is minimally affected by all influencing factors and is therefore considered the best site for selection. Conclusion: Expert ratings inherently involve subjectivity. To address this, a consistency check is conducted, and upon calculation, the consistency check passes, affirming the accuracy of the metric weights and rankings. This approach exhibits a certain degree of correctness and scientific rigor.
