摘　　要：介绍了数字化变电站通信系统过程层网络的组网原则和拓扑结构,并对不同组网方式的优缺点进行比较分析。以110kV变电站为例,采用以面向功能为原则的组网方式组建过程层网络,利用OPNET网络仿真软件对数字化变电站过程层网络数据传输的实时性、可靠性和对时精度进行仿真测试。仿真结果表明,通信网络延迟时间、数据传输实时性均符合IEC 61850标准规定,验证了网络数据传输的可靠性。This paper introduces networking principles and topological structure of process level of digital substation communication system, compares and analyzes merits and demerits of different networking ways. Taking 110 kV substation as an example, it proposes to use networking way based on function-oriented principle to build process level and use OPNET simulation software to proceed simulation testing for real-time, reliability and time precision of data transmission of process level. Simulation result shows that both of delay time and data transmission real-time of the communication network meet the specification of IEC 61850 standard and verifies reliability of network data transmission.
