As substations have an extremely important role in the power system, it is of great significance to construct a scientific comprehensive evaluation system for substations. Firstly, we construct the substation evaluation system model containing social indicators, safety indicators, economic indicators and energy efficiency indicators, and then determine the indicator weights based on the Entropy Weight Method, and simulate and analyse the actual substation, and introduce the Grey Relational Analysis to rank the comprehensive level of the substation, and the results show that the comprehensive evaluation indicators and model can reflect the comprehensive level of the substation.
