Key Technology Modeling of TSN Based on IEC 61850

In order to enhance the interconnection, interworking and interoperability of power utility automation system, IEC 61850 standards have been formulated for system functional architecture, equipment deployment, abstract modeling, data normalization communication services. It is only global standard in field automation. This realizes standardization engineering operation makes implementation standardized unified. With sharp increase amount smart grid data, requirements low latency high reliability control information transmission are increasing. expansion business types, demand IT OT fusion becoming more urgent. TSN was born bandwidth, latency, jitter integration OT, which perfectly meets needs system. paper mainly carries out key technology modeling based on 61850, deep puts forward a new idea improving service quality provides reference scheme follow-up pilot deployment
