Abstract：Intelligent terminals are key equipment for realizing the intelligentization of substation. Comprehensively and accurately assessing the operating status of the intelligent terminals has a great significance for ensuring the security of the power grid and formulating a scientific maintenance strategy. From the three information sources of offline indicators, environmental indicators, and dynamic indicators, this article establishes a set of factors including 10 related indicators including equipment operation environment, status, and parameters, builds a fuzzy comprehensive evaluation model, and proposes the maintenance strategy of intelligent terminals devices. At the same time, the dynamic membership and multi-source information decision fusion method based on deterioration characteristic correction are used to improve the adaptability of the state evaluation model. The analysis results of the calculation verify the feasibility and effectiveness of the method.
