英文摘要： Compared to traditional substation, the secondary system of smart substation has been cyberized. The physical wiring of the secondary circuit has been replaced by virtual communication signals. Therefore, fault detection and analysis methods based on secondary circuit cannot be applied in smart substation. However, the intelligentization and networking of substation provide research foundation and technical realization means to achieve more intelligent, integrated and deep going fault diagnosis and evaluation methods. The basic idea of the subject is to establish a smart substation standard diagnosis information model by using communication information modeling techniques; to establish unified diagnosis models of primary and secondary systems; to explore the deep-seated reasons of faults by insight into secondary system and communication network, and provide solutions; to present automated and smart means for operation management and maintenance of smart substation. The research content and key technologies of this subject include: modeling of fault diagnosis and communication information; constraint rules of primary system, secondary system and communication network knowledge; evaluation method and its parameter calculation ; fault reasoning methods and its process. This project will establish the theoretical f
