Research On Data Modeling Of Distribution Network Based On Distributed Technology

Distribution network modeling is of great significance for maintaining distribution network database,power flow calculation,short circuit calculation,network reconstruction,etc.The distribution network is different from the energy management system network.The specific structure and application software requirements determine the characteristics of large data volume,wide distribution,and complex models.Therefore,it is necessary to conduct special research on distribution network modeling.To meet the needs of research and development of distribution networks.With the advancement of technology and information,the power data collection equipment in the power grid has become more diversified,the amount of data collected is also increasing rapidly,the amount of data is huge and the data format is not uniform,resulting in a lot of inconvenience in information sharing and data interaction of various systems in the power grid.Therefore,how to deal with and analyze the distribution network model with big data technology is of great significance.This paper first analyzes the research background and development status of domestic and foreign power grid data modeling techniques.A brief introduction to the IEC 61970 standard and the CIM model provides a generic power system model.Then introduces the XML and XML parsing techniques,and compares and analyzes the commonly used XML parser.Then it introduces the distributed related big data technology,in which HBase is the distributed database of the HDFS storage model based on Hadoop,when processing big data.Efficient,flexible and scalable.This paper also studies CIM/XML topology analysis and import technology,and uses Dom4j to implement XML document parsing.Finally,this paper designs and implements the network-wide data modeling system of the distribution network,focusing on the grid model merging method and the whole network data model establishment process,and realizes the visualization operation using SVG technology,and designs and implements the two substations.The model merges the examples to verify the availability of the distribution network model.
