摘要
根据配电网分布式控制业务的特点及对通信系统的要求,采用光纤通信方式,给出无源光网络(Ethernetpassive optical network,EPON)和工业以太网交换机技术用于配电网分布式控制的解决方案,并对系统实时性要求进行分析计算,给出工程应用中具体设备及时延需求估算系统最大节点数量的关系式;最后,将该关系式用于配电网自动化实时传输时延要求和IEC61850标准中面向通用对象的变电站事件(generic object orientedsubstation event,GOOSE)报文传输延时要求的计算,计算结果表明2种技术均满足系统实时性要求。
In accordance to characteristics of distributed control service of distribution networks and its requirements on communication system, optical fiber communication mode is adopted and the solution of applying passive optical networks （PON） and industrial ethernet switch technologies in distributed control of distribution networks is employed; furthermore, real-time requirements of the system are analyzed and calculated, and relational expression that can estimate maximum of system nodes according to the specific equipment and time delay is offered. In conclusion, the relational expression is used in calculation on time delay of real-time transmission of distribution network automation and time delay requirement of messa- ging transmission of generic object oriented substation event （GOOSE）. The calculation result shows that both of the technologies can meet the real-time requirements.
