| 摘要: |
| 从变电站自动化系统的分层分布式结构及其通信任务和要求出发,分析了目前现场总线技术标准过多,信息交互困难及通信控制器不易扩展,开放性、灵活性不强的缺陷。提出基于以太网的变电站自动化系统,重点论述了基于网络控制的分布式变电站自动化系统网络结构简单、设备通用、通信速率快、全双工通信等优点;特别给出了嵌入式以太网的应用模式(每个间隔层设备配置一个以太网接口、多个智能电子设备通过RS-232/485或现场总线与以太网连接、以上2种的混合模式);最后,指出采用交换式高速以太网,并使节点工作在全双工方式,能满足变电站数据传输的实时性和可靠性要求。 |

| Abstract: |
| Based on the layered and distributed structure of the substation automation system and its communication tasks and requirements,defects of the field bus technology are analyzed,such as too many standards,difficult information interactions,inconvenient communication controller expansions,insufficient opennesses and flexibilities and so on.A substation automation system based on Ethernet is put forward,which has simple network structure,universal devices,fast communication speed and full-duplex transmission.Three application modes of the embedded Ethernet are presented:one Ethernet interface for each device in cell;communication manager with Ethernet interface for IEDs(Intelligent Electronic Devices) connected via RS-232 / 485 or field bus;hybrid mode of both.The solution for real-time and reliable data communication of substation is the application of exchange high-speed Ethernet and the full-duplex mode of nodes. |
