摘　　要：信息网和物理电网的融合与协作是未来智能电网的重要特征之一,构成了典型的信息物理系统CPS(cy⁃ber-physical system)。在电力信息物理系统CPPS(cyber-physical power system)中,信息空间的扰动和故障将增加物理系统运行风险,在评估CPPS的动态行为时必须详细考虑信息网的影响。基于OPC技术实现了电力系统仿真工具DIgSILENT和信息系统仿真工具Matlab的联合运行,建立了电力信息物理系统仿真平台。以广域阻尼控制为例进行电力系统与广域测量通信系统的联合仿真,结果表明,所建仿真平台能够有效反映系统中信息系统和物理系统的交互影响,所采用的广域阻尼控制能够有效抑制电力系统低频振荡,进而验证了平台的有效性。The integration and cooperation between an information network and a physical power grid is one of the im⁃portant characteristics of smart grid in the future,which constitutes a typical cyber-physical system(CPS).In a cyberphysical power system(CPPS),disturbances and failures in the information space will increase the operation risks of the physical system.As a result,the influence of the information network must be taken into account in detail when eval⁃uating the dynamic behavior of CPPS.Based on the object linking and embedding for process control(OPC)technolo⁃gy,the joint operation of the power system simulation tool DIgSILENT and the information system simulation tool Mat⁃lab is realized,and a simulation platform of CPPS is established.The wide-area damping control is taken as an example to jointly simulate the power system and the wide-area measurement communication system.Results show that the estab⁃lished simulation platform can effectively reflect the interactive influence of the information system and the physical sys⁃tem in the system,and the adopted wide-area damping control can effectively suppress the low-frequency oscillation of the power system,thus verifying the effectiveness of the platform.
