【摘要】：本文对检修体制的演变以及实施的不同方向进行了简要概括性的描述。如今,在电网逐渐坚强化和智能化的现状下,状态检修的重要性也便日益凸显出来。而在电网中扮演着重要角色的变电所则毋庸置疑得更为需要状态检修的支持。本文通过对朝阳沟变电所的各种变电设备的研究,分析变电设备的不同状态监测信息,并对朝阳沟变电所的主接线图进行适当合理地简化,深入研究状态检修于变电所中的应用。状态检修包括有三个环节:状态监测、状态评估、检修决策。这三个环节是循序渐进并依次进行的。前两个环节是完成状态检修的基石,而完成状态检修的目标及核心便是检修决策。为了科学直观地开展状态检修,重中之重就是要做好对应的检修决策。本文选取了3种不同的决策支持模型:比例失效模型、决策树和D-S证据理论,通过这三种模型在多种方面对状态检修作出优化。
[Abstract]:In this paper, the evolution of the maintenance system and the different directions of the implementation are briefly described. Now, the importance of state maintenance is becoming more and more important in the current situation of the gradual strengthening and intellectualization of the power grid. Through the study of various substation equipment of Chaoyang trench substation, this paper analyzes the different monitoring information of the substation equipment, and simplifies the main wiring diagram of the Chaoyang ditch substation, and deeply studies the application of the state maintenance in the substation. The condition based maintenance includes three links: state monitoring, state assessment and overhaul decision. The three link is gradual and sequential. The first two links are the cornerstone of the completion of state maintenance, and the goal and core of the state maintenance is the maintenance decision. In order to carry out the condition maintenance scientifically and intuitively, the most important thing is to do the corresponding maintenance decision. In this paper, 3 different decision support models are selected: proportion failure. Model, decision tree and D-S evidence theory are used to optimize the condition based maintenance in these three models.
