Research on Power Grid Data Sharing and Transmission Based on Information Modeling
In the process of power grid data sharing and transmission,it is difficult to ensure real-time data transmission if the business is suddenly abnormal and the network resources are seriously congested.Aiming at this problem,a power grid data sharing and transmission method based on information model is proposed.The power grid public information model is established based on power grid business.The data classes in the model are expanded according to the characteristics of power grid business,and the entity classes in the model are improved through inheritance,association,aggregation,and other operations,to determine the internal logical relationship of the model.On this basis,the operation rules of the model are formulated,and the data transmission service model is designed for different numbers of terminal requests to realize power grid data sharing and transmission interaction.The data sharing access control policy is designed for the cross-domain characteristics of data sharing to ensure the stability of data sharing and transmission.The experimental results show that the proposed method has small network delay and low packet loss rate.The proposed method can improve the real-time transmission of power grid data and provide reference for the reliable transmission and safe operation of grid data.
