Abstract
With the goal of reducing the delay of substation communication network,this paper designs a low delay con-trol method based on time sensitive networks.Firstly,in the station control layer and process layer of the substation com-munication network,time sensitive network switches are used to construct time sensitive subnetworks,and different switch terminals are identified as multiple linear parameter models.Then,fuzzy control method is used to control the synchroniza-tion clock error of the switch,and fuzzy rule antecedents for low latency control are determined based on fuzzy C-means clus-tering method.Fuzzy rule antecedents are obtained through parameter identification of time sensitive networks.Finally,based on the pre and post components of fuzzy control,combined with fuzzy control and generalized predictive control,feed-back correction of time sensitive network delay is achieved.The experimental results show that after using this method to control the delay of the substation communication network,the maximum delay of network communication is controlled within 100μs,and the maximum delayjitter is controlled within 20μs,indicating that this method effectively achieves the design expectations.关键词
