基于IEC 61850的智能配电通信网络仿真平台设计

可靠性、实时性、双向性是智能配电网通信系统必须满足的要求。在当前智能配电网通信系统分析的基础上，基于最新的IEC 61850标准，对智能配电网业务流量以及通信需求进行建模。在开源的多协议网络仿真软件 OMNeT++平台上建立了智能配电网通信网络仿真模型。仿真研究了在加入大量的分布式能源以及电动汽车等数据流量业务的背景下，过程层IED和站控层配电子站之间的通信交互过程，对比分析了在不同带宽、不同业务流量背景下IED和配电子站进行信息交互过程的传输时延。

Communication Network Simulation Platform Design of Intelligent Power Distribution Based on IEC 61850

Reliability, real-time performance and bidirection are the requirements of the communication system of intelligent distribution network. Based on the analysis of current intelligent distribution network communication system and the latest IEC 61850 standard, this paper constructs the model for the traffic and communication needs of the intelligent distribution network. We build the simulation model of the communication network in intelligent distribution network on the OMNeT++, which is an open source platform of multi protocol network simulation software. In the background of the data flow which adds a large amount of distributed energy and electric vehicle, we study the communication process between the process-level IED and the station-level distribution substation, and compare the transmission delay of IED and distribution substation under different bandwidth and traffic background.
