Abstract: Scheme evaluation for decoupling electromagnetic loop network can assist operating personnel in determining the optimal decoupling scheme, and provide an important reference for the planning and construction of power grids. First, the basic principles of fuzzy analytic hierarchy process (FAHP) are introduced, and then a new FAHP-based scheme evaluation method is proposed for decoupling electromagnetic loop networks based on a set of indicators reflecting the performance of the decoupling schemes. The proposed method improves the consistency of the fuzzy judgment matrix, and combines the advantages of fuzzy comprehensive evaluation and analytic hierarchy process. On the one hand, analytic hierarchy process effectively combines qualitative and quantitative analysis to ensure the rationality of the evaluation model; on the other hand, the judgment matrix and qualitative indicators are expressed with trapezoidal fuzzy numbers to make decision-makings more realistic. The effectiveness of the proposed method is validated by the application results on the real power system of Anshan region.
