摘要

This article proposes a relation-based fault diagnosis method for distribution substations based on the fuzzy sagittal diagram. In the inference procedures, the sagittal diagram was first built to represent the relations between a fault and actions of protective devices, and then the fuzzy set theory was applied to the diagram in dealing with the uncertainties inherent in the protection systems. The proposed method is capable of inferring the fault sections even for the situation of multiple faults. When tested at a typical secondary substation of Taipower Co., the proposed approach has shown some clear advantages in its rapid reasoning and the ability to handle uncertainty.
