The advanced IEC 61850 smart transformer has shown an improved performance in monitoring, controlling, and protecting the equipment in smart substations. However, heterogeneity, feasibility, and network control problems have limited the smart transformer's performance in networks. To address these issues, a software-defined networking model was proposed using ISO/IEC/IEEE 21451 networks. An IEC-61850-based network controller was designed as a new kind of intelligent electrical device (IED). The proposed data and information models enhanced the network awareness ability and facilitated the access of smart sensors in transformer to communication networks. The performance evaluation results showed an improved efficiency.
