Several Key Technologies for the Automatic Security Device of Digital Substation

The promotion of digital substation brings new challenges as well as new opportunities to the secondary automation equip- ments including automatic-security device. This paper mainly introduces four key technologies applied to the automatic-security device used in the process of digital substation. The four key technologies includes stability control and spare power automatic switch function integration design, CT range intelligent switch, the generation of state intelligent identification, and tester collaborative testing tech- nology. These new technologies will give full play to the practical application of automatic-security device in digitized substation tech- nology. In the future, these four key technologies will lay a solid technical foundation for the security automatic device＇ s large-scale application in digital substation.
