摘　　要：随着电力系统与信息通信系统耦合程度的不断加深,通信带来的信息延时、数据丢包和网络链接中断等问题使得传统的电力系统仿真方式(解耦通信或理想通信仿真方式)难以满足现实的需求。文中在分析现有信息物理系统(CPS)建模技术的基础之上,设计了基于MATLAB和OPNET的主从式CPS协同仿真平台。详细阐述了协同仿真平台的系统架构,以及协同仿真平台中的物理系统模型、信息系统模型、仿真交互模型和基于软件的虚拟量测设备的建模实现方式,重点分析了所设计的融合式时间同步策略。最后通过微电网仿真算例,验证了所建立的协同仿真平台及其时间同步策略的准确性和有效性。Along with the deeper coupling between power system and information communication system, such traditional simulation methods as decoupling communication and ideal simulation can hardly satisfy the realistic demand because of the communication faults of time delay, bit error and interruption. Based on an analysis of existing modeling techniques of cyber physical system, a master slave mode co-simulation platform supported by MATLAB and OPNET is proposed. Some key problems such as the co-simulation framework, the model in MATLAB and OPNET, software-based virtual measuring equipment and interactive interface are expounded, in which a hybrid time synchronization strategy is designed and analyzed. A microgrid case study is given to demonstrate the feasibility and availability of the co-simulation platform.
