With the rapid growth of power grid data and the development of communication technology,the new power system has higher requirements for real⁃time and sharing of data transmission.To solve this problem,this paper designs a technical scheme of data sharing and efficient transmission based on the power grid information model.Based on the establishment of a standardized power grid information model,the physical characteristics of electrical signals are extracted,the characteristic parameters of information are obtained by signal identification algorithm,and then the data analysis and restoration are realized by analysis and fitting.ASN coding rules are used to dynamically encode the information,and ISO is used to generate standard data frames in the data link layer,which effectively enhances the real⁃time performance of data transmission.The simulation platform is built to analyze and test the data transmission of the power grid information model.The comparative test results verify that the transmission technology scheme proposed in this paper has good sharing performance and high transmission efficiency.
