| 摘要: |
| 提出了一种基于以太网通信的变电站自动化系统的建构模式，基于这一模式，就如何在以太网上实现高效可靠的数据传输进行了研究。通过综合分析，选择TCP／IP模型及UDP(User Datagram Protocol)协议用于完成以太网通信任务，并详细阐述了UDP协议在通信控制层、变电站层的实现方法。根据变电站自动化系统中数据通信的特点，提出了可同时对通信速度和通信可靠性进行有效便捷评估的“1s未更新概率”的数学计算方法：并借助此概率的计算对提出的以太网通信方案进行评估。 |

| Abstract: |
| A communication model based on Ethernet for substation automation system is broughtforth and the realization of efficient and reliable communication is studied for this model. TCP/ IPand UDP(User Dategram Protocol)are adopted in Ethernet-based communication and the imple-mentation of UDP at communication control layer and substation layer is detailed. According to thedata communication features of substation automation system,the concept of Not- refreshed- per-se-cond probability is induced for the effective and easy evaluation of communication speed and reliability. It is applied here to evaluate the proposed communication scheme. |
