Design about Real-time Fault Detection Information System of the Transformer Substation

摘要

Nowadays, the automation of our country’s power grid operation and management has reached a high level, by contrast, the automation of analysis and management of relay protection monitoring, system fault and protection action behavior seems relatively backward. This paper emphatically introduces the design of fault information system based on real-time detection platform aiming at 220kV transformer substation, including design of master station and sub-station, communication realization between master station and substation and security protection of the system and briefly clarifies the functions which the system can realize according to the characteristics of power grid.
