This paper discusses the limitations of present research on smart substations and analyzes crucial technolo-gies for the new generation smart substation, namely hierarchical protection, integrated measuring-control devices, on-line monitoring and evaluation for the secondary electrical equipment. Based on analytic hierarchy process ( AHP) and fuzzy comprehensive evaluation, a method to evaluate economic performance of the substation is proposed. First, the structural model is established for the economic factor in the whole life cycle of the substation. Then a comprehen-sive evaluation system for the economic performance of the substation is constructed, and the evaluation and calcula-tion method of the factors in the system are deduced. Evaluation on an 110kV new generation smart substation shows that the it can effectively reduce the life-cycle cost of the substation.
