电磁环网解环方案评估能够辅助运行人员确定最优解环方案，为电网的规划与建设提供重要的决策参考。介绍了模糊层次分析法的基本原理，在构建一组反映解环方案优劣的指标集的基础上，提出了一种基于改进模糊层次分析法的电磁环网解环方案评估方法。所提方法改进了模糊判断矩阵的一致性，综合了模糊理论和层次分析法二者的优点，既能将定性与定量分析有效结合，又考虑了专家决策的模糊性质，从而较为全面、客观、科学地评价解环方案的优劣。以鞍山电网实际系统为例，验证了所提方法的有效性。%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.
