Abstract: The development of intelligent substation makes the composition of substation more complicated, which affects the rapid fault diagnosis of intelligent substation. But the wide application of intelligent substation has greatly increased the amount of power grid information collection, which provides a data basis for rapid fault diagnosis of intelligent substation by means of data analysis. In this context, according to the intelligent substation and its fault characteristics, taking a specific substation fault example, this paper analyzes the specific application process and method of Petri net data analysis technology in intelligent substation fault diagnosis, which provides a reference for the accurate and rapid fault diagnosis of intelligent substation.
Keywords: intelligent substation; Petri net method; data mining technology
