| 摘要: |
| 电网的快速发展和大规模互联电网的形成，使电网特性由区域模式转向全局模式。电网运行和调度控制均呈现数据密集、通信密集和计算密集的特征，从而形成了复杂的网状服务调用关系以及多层次的消息传输流程，给电网运行态势变化预测和运行风险管控带来了新挑战，亟需对通信总线数据交互过程进行有效监视。首先提出了通信总线的全链路监视与分布式追踪技术框架。然后研究了服务调用链监视和消息分布式追踪的关键技术。最后介绍了工程应用情况。该技术的应用为电网调控系统数据传输和交互提供了全面、直观的状态信息，实现了系统隐患及时发现、故障原因精准追溯，增强了新一代调控系统通信总线运行状态监视和风险控制能力。 |

| Abstract: |
| With the rapid development of the power grid and the formation of a large-scale interconnected power grid, power grid characteristics have changed from a regional to a global mode. Power grid operation and dispatching control are data, communication and computing intensive. As a result, a complex network service call relationship and multi-level message transmission process are formed. This brings great challenges to prediction of power grid operational change and operational risk control. The new challenge calls for effective monitoring of the communication bus data interaction process. In this paper, the whole link monitoring and distributed tracing technology framework of the communication bus is proposed. Then the key technologies of service call chain monitoring and message distributed tracing are studied. Finally, the engineering application is introduced. The application of this technology provides comprehensive and intuitive status information for data transmission and interaction with the power grid control system, realizes timely detection of system hidden dangers and accurate tracing of fault causes, and enhances the operational status monitoring and risk control ability of the communication bus of a new generation control system.
