英文摘要： The development of modern power system has a tendency of structural diversity, diversification in operation mode and intelligence of control methods. Combining new technologies and methods of computer and network communication, this topic studies the integration, fusion and coordination of redundant information and distributed computing in station domain protection and control field. The targets are to improve the performance of protection and control system and guarantee the stable operation and intelligent coordination of power system. Establish the redundancy information identification and coordination treatment mechanism of digital substation. Explore coordinated control theories of intelligent protection. The research emphases are promotion and implementation of the multiple nodes parallel computing, fault-tolerant check, coordination scheduling and optimization of protection function. Based on the research, put forward new principles and methods of station domain protection. Make full use of information mining, artificial intelligent technology and multi-discipline collaborative protection and control technology. Construct station domain coordinating protection and control system which implements effective utilization of redundant information, multiple nodes parallel computing and complementarity of multip
