摘要
随着智能电网建设的推进,电力信息物理系统(CPS)的可观性和可控性得到了极大增强。电力CPS的信息采集、传输、处理等过程对电力业务的影响越发明显。建立电力CPS的动态联合仿真平台有助于为相关理论和应用研究提供坚实的技术支撑。文中对比分析了现有的联合仿真平台方案与架构,指出由于电力流和信息流在数学模型上的本质区别,需要建立实时联合仿真平台;基于电力仿真工具OPAL-RT和通信仿真工具OPNET,研制开发了数据交互接口及数据转换模块,建立了电力CPS实时仿真平台,能够高速、精确地模拟电力CPS动态响应特性。针对电力CPS负荷控制的仿真算例结果表明,所研制的电力CPS实时仿真平台具有合理性和有效性。
With the development of smart grid technology,the observability and controllability of power cyber-physical system（CPS）are greatly enhanced.The procedures of information collection,transmission and processing have more influences on power system services.The construction of dynamic co-simulation platform for power CPS will provide technical support for the researches of related theories and applications.The existing simulation schemes and their structures are analyzed.The essential difference between mathematical models of power flow and information flow makes it necessary to build a real-time co-simulation platform.Based on the power system simulation tool OPAL-RT and the communication simulation tool OPNET,a real-time simulation platform for power CPS is proposed with the originally developed data transmission interface and conversion module,which can precisely simulate the dynamic characteristics of power system with a high speed.A case study of load control system shows the reasonability and validity of the platform.
