数字化变电站过程总线通信关键技术研究

Key technologies for process bus communication of digital substations

过程总线通信是数字化变电站区别于现有变电站自动化系统的一个重要方面。介绍了过程总线这一新概念提出的主要前提条件,并针对过程总线通信的实现,分析了采样值报文传输所遵循的不同标准、采样同步、跳闸命令实时和可靠传输等关键问题。

Process bus communication is one of the key differences between the digital substation and current substation automation system. Some preconditions of the process bus communication are pointed out, and for the implementation of this new type communication, some key problems are analyzed, such as different standards about the transmission of sampled values, synchronization of the sampled values, and real-time and reliable transmission of the trip signals.
