摘　　要：在分析智能变电站通信网络过载产生原因的基础上,根据传输机制及实时性要求对几种典型的信息流进行分类,并针对智能变电站现有信息流队列调度策略存在的不足,结合加权公平队列调度策略(WFQ),提出一种适用于变电站通信网络信息流的综合调度策略(Integrated Scheduling Strategy,ISS)。以典型D2-1型变电站通信网络拓扑为研究对象,借助OPNET仿真平台对所提出的综合调度策略与严格优先级策略(SPQ)进行仿真对比分析,结果表明综合调度策略在一定程度上具有可行性。The cause of the communication network overload in the intelligent substation is analyzed. Based on the analysis, several typical information flows are classified according to the transmission mechanism and with the real -time requirement. In view of the shortcomings of the existing information flow queue scheduling strategy in the in-telligent substation, combined with the scheduling strategy of weighted fair queuing （ WFQ） , an integrated schedu-ling strategy （ISS） is proposed for information flow of substation communication network. Taking the communica-tion network topology of typical D2 -1 type substation as the research object, simulation and comparative analyses are made on the integrated scheduling strategy （ISS） and the strict priority strategy （ SPQ） proposed by using the OPNET simulation platforrrL The simulation results show that the integrated scheduling strategy is feasible to a cer-tain extent.
