摘要

电网信息物理系统(电网CPS)中信息层和物理层的紧密耦合，使得信息或物理的失效都会对电网CPS的正常运行造成影响。文中提出了一种基于关联特性矩阵的电网CPS建模方法，对电力系统控制应用中信息流与能量流的复杂耦合关系和交互机理进行梳理与建模。该方法首先对实际电网CPS逻辑进行梳理与抽象，得到电网CPS基本分析单元；然后，采用多元组定量描述信息节点、二次设备节点和通信节点的外特性，采用关联特性矩阵的方法定量描述电网CPS中物理层、二次设备层、通信层、信息层内部及其相互之间的逻辑关联关系及特性，形成完整的电网CPS耦合模型。最后，基于电网CPS模型对实际电网CPS应用系统进行分析，说明模型的使用方法，验证模型的合理性和有效性。

Abstract

Since the information layer and the physical layer in the cyber physical power system(CPPS)are closely coupled

the failure of cyber or physical system will seriously affect the normal operation of power system. This paper proposes a correlation characteristic matrix based modeling method for the coupling system to comb and quantify the complex interaction mechanism of information flow and energy flow in the control applications of power system. In this method

the basic analysis unit of CPPS is abstracted from the actual power system applications. Then

the external characteristics of the information nodes

secondary device nodes and communication nodes are described by the expandable multivariate sets. Moreover

the logical association relation and characteristics of physical layer

secondary device layer

communication layer

and information layer are quantitatively described by the correlation characteristic matrix method. Therefore

a complete CPPS model is formed. Finally

an actual power system based on the proposed CPPS model is analyzed

and the usage of the model is illustrated. The results have verified the rationality and effectiveness of the proposed model.
