摘　　要：时间敏感网络作为一种确定性网络技术,能够解决数字化变电站采样值(sampled values,SV)消息传输可靠性偏低、时延不确定等问题。文章首先分析了SV消息的流量特征,给出了3种时间敏感网络调度方法;然后,以典型变电站过程层结构为基础,对3种调度方法进行了仿真;最后,通过分析时延和带宽利用率得到Hold/Release机制与时间感知整形器(time aware shaper,TAS)、帧抢占机制联合调度方法更适合数字化变电站SV消息的传输的结论。研究结论对数字化变电站SV消息的传输性能优化具有重要价值。As a deterministic network technology,time-sensitive network can solve the problems of low reliability and uncertain transmission delay of SV message in digital substation.Firstly,the traffic characteristics of sampled messages are analyzed,and three time-sensitive network scheduling methods for sampled messages are presented.Then,based on the typical substation process layer structure,three scheduling methods are simulated.Finally,by analyzing the delay and bandwidth utilization,it is concluded that the joint scheduling method of Hold/Release mechanism,TAS and frame preemption mechanism is more suitable for SV message transmission in digital substation.The research results are of great value to the optimization of SV message transmission performance in digital substation.
