本文的目的是提出一种基于模糊逻辑、专家系统技术和多标准决策理论的模糊专家系统方法（FESM），可用于为电网的每个测量点（使用特定时间段的测量值）计算唯一的模糊总电能质量指数（FTPQI）。特定点的FTPQI包括有关其PQ水平的统一和集中的信息，并且可以有助于对所检查的电网节点的评估，使用相应的FTPQI在PQ方面提供它们之间的排名。系统管理员可以使用该工具提供可靠、科学的方法来检查一般和特定点的电网总 PQ，并且还提供临时网络改进补救措施的可能性。 （6页）
The aim of this paper is to present a Fuzzy Expert System Methodology (FESM), based on the Fuzzy Logic, Expert System techniques and multicriteria decision making theory, which can be used to calculate a unique Fuzzy Total Power Quality Index (FTPQI) for every measured point of the electric network (measurements for a specific time period are used). FTPQI of the specific point includes unified and concentrated information about its PQ level and could contribute to the evaluation of examined electric network nodes providing a ranking between them in terms of PQ using the corresponding FTPQI. This tool could be used by the system administrator giving a reliable and scientific way to check the total PQ of electric networks in general and at specified points and, also, providing the possibility of ad-hoc network improvement remedies.
