Abstract


Grid fault diagnosis has been a popular research topic at home and abroad , and has important theoretical and practical value . Complete fault information to obtain a power grid fault diagnosis can be performed precondition for access to information , timeliness, completeness, will determine the relevance and effectiveness of the power grid fault diagnosis . The fault diagnosis system of data derived from the failure information systems and SCADA / EMS . Due to the lack of a unified information model between heterogeneous systems , from the syntax and semantics of the definition of information between different systems in the dispatch center , there is no uniform standard , its information sharing and interaction between very difficult . Fault information is incomplete , the format is not unified , reducing the efficiency of the diagnosis of the fault diagnosis system , use of them is affected . Extend and coordination based on the IEC61970 standard and IEC61850 standards , information modeling and model data grid failure , the establishment of the UML form a unified information model , data integrity and consistency of the information , and based on a unified information the model was constructed to meet the interoperability of grid fault diagnosis communication system . And then on the grid topology extraction and defines the data structure for fault diagnosis algorithm . The data structure base, a complete description of the grid parameters of the devices , the data and its relationship to the the IEC61850 logical node and the IEC61970-CIM . Based on the above data and models , using the ActiveX control technology to design a grid fault diagnosis simulation platform , grid graphical information and database the gallery integration of grid topology generation and improve real-time search , data editing , display and read take a more flexible , enhanced fault diagnosis system interoperability . Grid fault diagnosis communication system based on the model and the data structure built to solve the complete information of fault diagnosis system and data standardization , has good versatility and portability to meet grid interoperability , distributed, heterogeneous to structure grid online , real-time fault localization diagnosis and fault diagnosis results can be shared with other systems .
