| 摘要: |
| 采用健康指数理论对变压器运行状态进行分级评估。通过复杂网络理论建立电网拓扑模型，以节点重要度指标来表征变压器运行状态对电网的影响。结合节点重要度对变压器状态评估结果进行修正，制定全网设备的检修次序。以某电网实际数据为例对所提方法的可行性及有效性进行了验证。 |

| Abstract: |
| The operating state level of transformer is evaluated by using the health index theory. The power grid topology model is established by the complex network theory, and the impact of the operating status of the power transformer on the power grid is represented by node importance index. Combined with the importance of nodes, the transformer state assessment results are modified and the maintenance sequence of all equipments in power grid is worked out. The feasibility and validity of the proposed method are verified by the actual data of some power grid. |
