| 摘要: |
| 准确、高效的输电线路状态评估是开展智能化维护的关键。在大量收集输电线路多时段或全时段的检修数据的基础上，利用风险评估方法，建立风险信息熵评估模型，以准确评估线路状态和确定线路单元检修策略。通过分析状态量主成分，根据主成分占比求取分值并排序，建立具备差异化特征的输电线路主成分状态量评价体系，以提高检修效率。结合层次分析法、主成分分析法及风险信息熵，以最小偏差为最优权重目标函数，确定各状态量风险的优先级，优化检修目标。通过应用于中部省份某500 kV输电线路的状态检修，验证了该模型合理、可行。 |

| Abstract: |
| The accurate and efficient assessment of the transmission lines state is the key to carry out the intelligent maintenance. In this paper, based on a large collection of multiple period or full-time maintenance data of transmission line, the model of risk information entropy is established by using the risk assessment method to assess the transmission line state accurately, and the maintenance strategy for line unit is determined. After the state of the principle component is analyzed, the scores are calculated according to the proportion of main component and sorted correspondingly, and then the evaluation system with differentiation characteristics for the principle component state of transmission line is established to improve the efficiency of maintenance. The analytic hierarchy process, principal component analysis and risk information entropy are combined and the objective function of optimal weight with minimum deviation is adopted to determine the priority of the risk of each state and optimize the maintenance target. Through the application in the state maintenance of a 500 kV transmission line in a central province, it shows that the model is reasonable and feasible.
