Condition Assessment of Power Cable Based on Fuzzy Analytic Hierarchy Process and Set Pair Analysis Approach

Power cable is one of the most important components in energy internet and energy system integration. To provide a decision support for maintenance of power cable, this paper proposes a method for comprehensive operation condition assessment of power cable based on fuzzy analytic hierarchy process and set pair analysis approach. An evaluation indicator system of cable condition was established, and the operation state was divided into four ranks, including normal, attention, abnormal and serious state. Then the fuzzy analytic hierarchy process and set pair analysis approach were introduced for the condition assessment of power cable. Operation condition assessment of power cable was conducted with the proposed method through an actual example, and the result corresponds well with the actual situation.
