Zusammenfassung:	The invention discloses an intelligent substation secondary system fault accurate positioning method. The method comprises the steps of obtaining an SCD description file, a GOOSE message and an SV message of operation of an intelligent substation, and confirming the operation state of the intelligent substation; counting the operation data of the secondary system of the intelligent substation, and classifying and integrating different types of data; normalizing and integrating the operation data of the intelligent substation and the data in the data archive; and constructing a fault detection model, and performing training according to fault data. According to the invention, the fault node can be quickly and accurately positioned, the fault diagnosis and repair efficiency is improved, the downtime and maintenance cost of the power system are reduced, and the reliability and safety of the power grid are further improved. Meanwhile, the method also provides valuable data support for operation and optimization o
