On November 30, the project of "Research and Development of Key Technology for Information Exchange in Smart Distribution Network" undertaken by China Electric Power Research Institute and project of "Research and Development of Online Monitoring and Risk Assessment Technology for Reliability of Intelligent Distribution Network" were approved by China Electrical Engineering Society Identification of scientific and technological achievements, the two projects to achieve a number of key technological breakthroughs. The appraisal committee thinks that the research on the key technology research and development of information exchange in smart distribution network is innovative in information distribution bus, information model database and power distribution terminal adaptive access in intelligent distribution network. Grid information integration, interoperability and business systems management ability to enhance the promotion of an important role, the overall reached the international advanced level; "intelligent distribution network reliability monitoring and risk assessment technology research and development" project research in the distribution network risk assessment indicators System, risk model and identification of weak links. The research results have enhanced the risk management capabilities of distribution network operation and achieved overall leading level in the world.
"Intelligent Power Distribution Network Information Exchange Key Technology Research and Development" project proposed based on information exchange bus distribution network unified business information management technology program to achieve business orchestration, information flow visualization and anomaly analysis technology; developed based on IEC61968 standard Of the distribution network information exchange bus to achieve the bus based on the active analysis and control, application adapter distributed coordination of the optimal operation of the technology; proposed based on CIM / XSD native XML and relational hybrid distribution network model data storage method, research and development The distribution network information full model database and data resource service system are proposed. The plug-and-play method of distribution automation terminal based on IEC61850 standard and WebService and the real-time topology construction method of distribution terminal based on CIM are proposed. The distribution network automation terminal Interoperability service system to achieve adaptive access to distribution terminals. The project achievements have been successfully applied to distribution networks in seven cities such as Chongqing and Xiamen.
"Intelligent Distribution Network Reliability Monitoring and Risk Assessment Technology Research and Development" project proposed a comprehensive consideration of the distribution network operation mode, equipment health status, load uncertainty, randomness, external influences, distributed power access and other factors Based intelligent distribution network online risk factor library and risk assessment index system for multi-dimensional quantitative assessment of operational risk of smart distribution network provides a scientific basis for the construction of a smart grid risk assessment application and in accordance with the IEC61968 standard diagram, number and Library integration of multi-source information fusion platform, the development of intelligent distribution network reliability online monitoring, risk assessment and visualization of early warning system. The project achievements have been successfully applied to the demonstration zones of high reliability and the distribution network demonstration areas of key cities in Chongqing, Xiamen and Qingdao.
