Abstract A great number of monitoring technologies have been developed especially for complex systems within the critical zones such as electric power substations, nuclear energy systems. But also, there is no single instruction or standardization in fault-focused on-line/off-line monitoring applications due to the acceleration of technological developments. Field experts have difficulty in choosing which test and measurement systems should be used in which stage of the complex systems. In this study, the propositional logic-based concept is presented, which field experts can use to manage this process. In this concept, test and measurement systems can be grouped according to the priority-order. According to the results of the graded groups on this concept, the suspected fault is verified by the cause of the occurrence. The applicability of the proposed concept has been tried to be explained by creating possible failure scenarios on the transformer. The theoretically validated concept can be used for even more fault situations. This concept can also be used in another complex systems with a large number of T&M systems where very different fault conditions can occur. 2009 Elsevier Ltd. All rights reserved.

复杂系统故障诊断的命题逻辑概念

摘要 针对变电站、核能系统等关键区域内的复杂系统，已经开发了大量的监测技术。而且，由于技术发展的加速，针对故障的在线/离线监控应用没有单一的指令或标准化。现场专家很难选择在复杂系统的哪个阶段应该使用哪些测试和测量系统。在这项研究中，提出了基于命题逻辑的概念，领域专家可以使用它来管理这个过程。在这个概念中，测试和测量系统可以根据优先顺序进行分组。根据对这个概念的分级组的结果，通过发生的原因来验证疑似故障。已尝试通过在变压器上创建可能的故障场景来解释所提议概念的适用性。经过理论验证的概念可用于更多故障情况。这个概念也可以用于另一个复杂的系统，其中有大量的 T&M 系统，其中可能发生非常不同的故障条件。2009 Elsevier Ltd. 保留所有权利。
