Reliability Analysis Method for Power Transmission and Transformation Systems Based on Fuzzy Analytic Hierarchy Process
The reliability analysis judgment matrix for power transmission and transformation systems generally adopts the form of objective analysis,which has low judgment efficiency and leads to a decrease in the proportion of reliable nodes.Therefore,this paper proposes the design and verification analysis of a reliability analysis method for power transmission and transformation systems based on fuzzy analytic hierarchy process(FAHP).According to the current measurement,it is necessary to first determine the reliability evaluation indicators,adopt a multi-level approach to improve the judgment efficiency,and complete the setting of the multi-level judgment matrix.On this basis,a fuzzy hierarchical reliability analysis model for transmission and transformation systems is constructed,and continuous verification processing is used to complete the reliability analysis.The results show that for the selected four branches,after three cycles of measurement,the proportion of reliable nodes can all reach 3.8 or above,indicating that with the assistance of FAHP,the designed reliability analysis method for transmission and transformation systems is more realistic and efficient,and the actual application efficiency has been significantly improved,which has certain application value.
