Research on distributed on-line verification system for relay protection settings

In the inter-regional grid environment, the coordination of the relay setting and the grid run-time operating mode has an important significance to grid security, relay protection settings verification has also been a lot of attention. This paper studies relay protection setting on-line verification system based on distributed data exchange platform in the inter-regional grid environment, introduces the structure of the distributed system, multidimensional grid data management, grid operation mode model expansion based on CIM model, and discusses the operation mode the relay setting verification.
