【摘要】 将单台发电机组或变电站内的计算机控制设备利用网络连接起来,组成基于分层分布式结构的计算机监控系统,可以提高自动化控制程度。文中根据实际需要,对各种网络结构进行比较,重点结合新型的网络拓扑进行分析,并给出软件冗余的设计思想,讨论了针对不同系统构成的拓扑结构。更多还原

【Abstract】 The computer supervising control and data acquisition (SCADA) system is a distributed system. The interconnection of local control units can configure the computer network to monitor the power plants and transformer stations and can promote automatic controlling level of power system. In this paper,the network hardware structure is analyzed,and the software design method Which adopts the redundancy technology is given. Through comparing and analyzing different kinds of network topologies,a safer monitor system is discussed.更多还原
