摘　　要：为了有效提升变电站通信网络信号传输性能,需要进行信号传输路径实时性优化。但是采用当前工业领域测试方法存在效率低下,操作难度大的问题。变电站通信网络传输路径存在时延不确定性的难点问题。因此,提出一种基于动态建模技术构造满足IEC61850-5标准的D2-1型变电站通信网络模型的方法进行路径实时优化仿真。方法在研究变电站传输系统原理的基础上,应用精确的数学模型对变电站内智能电子设备间传输的综合数据流,业务传输路径进行全面时域建模。最后,应用优先级标签技术与控制变量法,对变电站通信网络传输路径实时性进行优化仿真。仿真结果表明,基于动态建模技术方法的变电站通信网络拓扑,网络负载,高层协议映射机制能有效优化变电站通信信号传输路径实时性。In order to improve the signal transmission performance of substation communication network, it is necessary to optimize the real - time of signal path. However, the current industry testing methods are inefficient and difficult to operate. Besides, there exists a key problem of delay uncertainty. Therefore, the OPNET Modeler was proposed for constructing a D2 - 1 substation communication network model specified by IEC61850 - 5 standard to simulate the real - time of transmission path. Firstly, the principle of substation transmission system was discussed. Secondly, on the basis of the transmission principle, an accurate mathematical model was applied for modeling the typical data flow and path profile which was transmitted between intelligent electronic devices. Finally, priority tag technology and variable - controlling approach were applied in the substation communication network research. The OPNET simulation results indicate that communication network topology, network load, the high - level mapping mechanism can effectively optimize the real - time of signal transmission path in substation.
