电力工业的特点使其生产、技术的管理乃至领导的决策都需要调度中心所收集的电网实时运行数据.本文研究以局部网络(LAN)构成的电力管理信息系统怎样实现与调度自动化实时系统的联结.并以流行的以太网络(Ethcrnet)为对象着重分析总线竞争型局部网络中电网实时信息的接收、传送和处理.
The characteristics of the power industry make it necessary for the real-time operation data collected by the dispatching center to be taken into account for the production, technical management and even decision-making of the leading power.This paper studies how the power management information system composed of local networks (LANs) can link with the real-time dispatching automation system In this paper, we focus on the analysis of the receiving, transmitting and processing of real-time information of power grid in the bus competitive local network by using the popular Ethernet (Ethcrnet).
