Abstract: As an important part of power transmission and conversion, it is of great significance to establish a scientific and comprehensive evaluation system for substations. However, the current research on substation evaluation focuses on economy and energy efficiency, ignoring the carbon emission and environmental impact of the substation, which leads to an inadequate evaluation of the substation. For this reason, a comprehensive substation evaluation system model containing economic, energy-efficiency, safety, environmental, and low-carbon indicators is established by adopting the concept of a life cycle, using hierarchical analysis to determine the weights of the indicators, introducing the ideal-solution approximation ranking method to analyze the actual substations, and providing scoring and ranking of the substation performance. The results show that the AHP-TOPSIS-based comprehensive evaluation index and model of the whole life cycle of the substation can reflect the performance of the substation and provide help for the optimization of the substation.
