配电网CPS的通信需求和网络资源分配方案探讨
|
摘要
分析配电网CPS与现行电信互联网系统的差异,指出通信网运行过程参与到自动化控制过程是其重要特征。将配电网CPS通信需求分为IT(information technologies)数据流和OT(operation technologies)操作2个层次,分别分析了其传输性能指标和可靠性机制。进而提出在一体化的承载网模型下,有效管理网络资源,构建出满足IT/OT不同需求的虚拟网络的多目标资源分配方案。最后通过配电网CPS的典型组网示例及其应用分析,验证了方案的合理性。
The paper analyses the properties of cyber physical system(CPS)for distribution network and the differences to telecom internet system,and points out that the CPS is characterized by that the communication network is involved in automatic process.The communication requirements are divided into two aspects including IT dataflow and OT control process,and their communication parameters and reliability mechanism are analyzed.Then,the universal carrying network model is proposed to improve the efficiency and ability of network resources management,and a multi-objective resource allocation scheme is established to meet the different requirements of IT and OT.Finally,the model and scheme is proved to be reasonable through a case study of a typical distribution network CPS.
