Intelligent Substation Switch Traffic Scheduling Model Based on Time-Sensitive Network

In order to solve the contradiction between data traffic growth and real-time control information in intelligent substation, this paper proposes a time-sensitive network (TSN)based intelligent substation switch traffic scheduling model, which uses new technologies to dispatch data link layer traffic. This technology adopts the idea of monopolizing and sharing the time slot window for traffic transmission time, using the mechanism of frame preemption in the traffic transmission channel, realizing traffic classification according to the traffic characteristics, and is used to improve the traffic scheduling mechanism of the process layer of the intelligent substation on the traditional switch, improve the effect of determining the time-sensitive traffic delay scheduling, provide traffic transmission services with low latency jitter for the Ethernet network of the intelligent substation, and put forward a new idea for the improvement of the service quality (QoS) of the power system.
