| 摘要: |
| 分析了分布式变电站自动化网络通信系统报文特点,其报文可分为周期性、随机性和突发性3种类型数据,确定实时性和可靠性是衡量报文准确传输的标准。提出将实时发布/订阅(RTPS)协议应用于变电站自动化网络通信系统中,节点通过“Publish”发送数据,通过“Subscribe”接收所需要的数据,节点在实时传输和可靠传输间作出折衷选择。采用OPNET Modeler仿真软件,创建基于RTPS的16节点的变电站自动化网络通信模型,对周期性、随机性和突发性3种类型数据的仿真结果证明所提出的方案满足要求。 |

| Abstract: |
| The characteristics of messages in distributed substation automation network commu-nication system are analyzed,and the messages can be divided into periodic,stochastic and un-planned data.The real-time performance and reliability of message transmission are applied as the criteria of veracity evaluation and the RTPS(Real-Time Publish/Subscribe) protocol is proposed for sub-station automation network communication system.Nodes send data through "Publish" and receive demanded data through "Subscribe".Real-time performance and reliability are considered synthetically.A 16-node substation automation network communication model is established based on RTPS using OPNET Modeler simulation software.Simulation results for periodic,random and unplanned data communication are satisfying. |
