调度自动化系统消息总线双网模式交叉故障的解决方案

Solutions for Cross Failure of Message Bus with Dual Network in Dispatching Automation System

在电网调度自动化系统中,消息总线作为一个重要的分布式通信中间件模块,实现了系统在不同进程之间、不同机器节点之间相互传递消息和数据的功能。而调度自动化系统由于对安全性、稳定性和可靠性的要求,在构建时通常采用双网冗余配置模式。文中对消息总线在双网交叉故障状态下实现消息可靠传输的机制进行研究,并提出解决方案,使系统在交叉故障情况下消息仍能正常投递,从而提高系统的可用性。

As an important distributed communication middleware, the message bus is often used to deliver messages and data between different processes or different computer nodes in a power dispatching automation system. Meanwhile, the dispatching automation system as usual deploys dual redundancy network for system security, stability and reliability. This paper studies reliable message delivery for the message bus with dual redundancy network in the cross failure condition and proposes solutions to achieving correct message delivery notwithstanding the failure, while improving the availability of the system.
