A smart transmission grid fault diagnosis and analysis system based on CEP technology

A smart transmission grid fault diagnosis and analysis system (FDAS) is presented based on the complex event processing (CEP) technology. Firstly, the basic concept of the CEP technology is introduced. Secondly, a systematic hierarchical structure of fault diagnosis and analysis system based on CEP technology is illustrated. Thirdly, the events and patterns are modeled on the extensible markup language (XML) files. Finally, case analysis shows that the FDAS is a system good at fast identifying cause during cascading failure, supplying optimum dispatching strategy, and avoiding blackouts effectively.
