The existing distribution automation systems face problems such as a lack of actual modeling of the low-voltage model,inconsistency of main and distribution network model as well as a shortage of means for model verification when being worked for the new distribution network.In order to effectively improve the lean management level of the new distribution network,this article takes the construction of a unified power grid model for the new distribution network as the entry point and combines the current access status of distribution automation system model data to explore four key technologies for the integration of new distribution network models:process management technology for integrated model fusion,model integration access management technology,model high simulation verification technology,and main distribution network splicing technology.The feasibility of these technologies has been confirmed through practical cases,improving the efficiency and accuracy of data integration for the distribution automation system model and meeting the needs of monitoring transmission,and distribution networks,as well as various analytical calculations for power grid modeling.
