摘　　要：以太网(Ethernet)应用于变电站自动化系统的过程层总线、厂站总线已经成为新一代变电站自动化系统的发展趋势。该文在深入研究Ethernet通信机理和报文传输本质概念的基础上,提出基于 Ethernet的变电站自动化系统中报文实时传输的满足条件、影响因素以及评价方法,并给出了相关的定义、公式、数学模型和分析结果。该研究结果对于变电站自动化系统网络通信的设计具有参考意义。最后在结合实践和研究结果的基础上,提出了一些值得进一步深入研究的问题。The trend of new substation automation is that Ethernet will be used for process bus and station bus of substation. By studying the basic principle of Ethernet and the concepts of message transfer, we present the content conditions, influence factors and evaluate methods for message real-time transfer in substation. We also give the exact definitions, formulas and analysis result for the first time. The researching result is valuable for communication design of the new substation automation based on Ethernet. Finally,on the basis of experience and researching results, some problems which are worth further studying are put forward.
