| 摘要: |
| 作为智能配电网的重要设备之一，电力变压器运行状态的准确判别和预警有重要意义。全面分析电力变压器状态量，建立由油色谱、电气试验、绝缘油试验、附件运行状况4个一级指标和18个二级指标组成的电力变压器状态评价指标体系。建立基于模糊综合评价和贝叶斯判别的电力变压器状态判别和预警模型。实例证明该模型能准确高效地判别变压器的工作状态并提出相应的预警和检修计划。 |

| Abstract: |
| Since power transformer is one of the important equipments in smart distribution network，the accurate discrimination and warning of its operating status is of great significance. The status variables of power transformer are comprehensively analyzed and a corresponding evaluation index system is built，including four first-level indicators，i.e. oil chromatography，electrical test，insulation oil test and accessory operating condition，and eighteen second-level indicators. A power transformer status evaluation and warning model is established based on the fuzzy comprehensive evaluation and Bayes discrimination. Example proves that，the model can accurately and effectively evaluate the operating status of power transformer and make a corresponding warning and overhaul plan. |
