| 摘要: |
| 为实现分布式控制关联站点智能终端(Smart Terminal Unit, STU)间的实时对等通信以及互操作，可采用面向通用对象的变电站事件(Generic Object—Oriented Substation Event,GOOSE)传输STU间的实时数据和控制命令。在对比分析现有GOOSE映射方式的基础上，提出了基于TCP协议的GOOSE报文传输方案(GOOSE over TCP)，给出了实现方法以及改善GOOSE over TCP传输实时性的措施。分析了影响报文传输延时的主要因素。通过试验测得在通信网络含有大量突发报文的恶劣环境中优化后的GOOSE over TCP最大传输延时约为2.4 ms，平均传输延时约为1.3 ms，可以满足配电网分布式控制应用的需求。 |

| Abstract: |
| For realizing the real-time peer-to-peer communication and interoperability between the distributed control application related sites Smart Terminal Units (STUs), the GOOSE (Generic Object—Oriented Substation Event) could be used to transfer real-time data and commands among STUs. Based on the analysis of the existing mapping mode of GOOSE, a GOOSE mapped to TCP transmission mechanism (GOOSE over TCP) is proposed. The implementation method and the improvement measures to increasing the real-time of GOOSE over TCP are given. The main factors that affecting transmission delay are analyzed. In the harsh environment which is full of the burst network message, after taking the improvement measures, the maximum transmission delay of GOOSE over TCP communication is about 2.4 ms, the average delay is about 1.3 ms, which could satisfy the needs of distributed control applications in distribution network.
