| 摘要: |
| 及时准确地了解电网运行健康状况具有非常重要的意义。介绍了电力系统健康诊断的概念，并提出用AHP-熵值法结合模糊理论对电网进行健康状况评估。从历史基础、在线运行、环境影响三个方面构建了电力系统健康诊断指标体系，并加入故障指标项，使指标体系更加完善，使评估更加客观、精确、具有说服力。通过诊断数据，找出电网自身的问题和变化趋势，从而预测整个电网的变化态势，对存在的隐患或者可能出现的电力系统故障给出应对的建议。最后通过对中国西南某地的实例分析，验证了该方法的可行性和有效性。 |

| Abstract: |
| It is very important to know well the health status of power grid operation in time and accurately. The concept of power system health diagnosis and evaluation is introduced in this paper. Health condition assessment of power system through the analytic hierarchy process (AHP) - entropy method and fuzzy theory. This paper constructs the index system of power system health diagnosis in terms of the historical basis, real-time operation and environment influence, in which fault indicator item is added to improve the original index system and make the evaluation more objective, accurate and persuasive. Its gap and changing trend are found by diagnostic analysis of the system through the diagnostic data and the suggestions on the anomalies are given out. The effectiveness and feasibility of the diagnostic method is verified by analyzing certain real power grid in southwest of China. |
