摘要
主要讨论了在采用分层体系结构的馈线自动化系统中如何实现各种数据的收集并保证故障信息的快速、优先上传。分析了馈线自动化系统中信息传输的特点 ,对 10 1规约与DNP3.0规约的事件收集机制作了比较 ,认为 10 1规约更适合各层间采用了不同网络拓扑结构的馈线自动化系统。探讨了 10 1规约在馈线自动化系统中实现时应注意的问题。分析了系统应采用的网络拓扑结构 ,讨论了在收集数据时 ,控制中心、区域工作站及FTU各自需实现的功能。分析表明 ,10 1规约能保证在馈线自动化系统中实现故障信息快速上传 。
This paper chiefly describes how to realize data acquisition and guarantee to transmit fault information quickly and preferentially in hierarchical structure of feeder automation system. It analyses the characteristic of information transmission in feeder automation system and compares the event collection mechanism between 101 protocol and DNP3.0 protocol, it is considered that 101 protocol is more adaptive to feeder automation system in which every hierarchical structure has different network topological structures. Then the application of 101 protocol to feeder automation system is discussed in detail, some special problems are analyzed. At last the network topological structure which should be used in the system is discussed, and the functions which should be realized in control center, district workstation and FTU each are also analyzed in this paper. These analyses indicate that 101 protocol can guarantee to transmit fault information quickly, thereby fault district can be insulated rapidly which is required by feeder automation system.
