摘要
广东省能量管理系统采用新型结构的前置机通信系统 ,在硬件上采用双重化配置 :双前置机、双电源、双卫星时钟、双以太网。文中介绍了前置机改主备运行切换方式为双机并列运行切换方式 ,双通道顺接和交叉口连接方式 ,支持不同规约、同步 /异步共线通信方式 。
The energy management system!(EMS) of Guangdong Provincial Dispatching Center adopts a new type front--endcommunication system. Its hardware design has a characteristic of double equipment. including double computers. doublepower sources, double satellite clocks and double Ethernets. Another feature of its front--end system is to change thecommonly used double (main and reserve) front--end computers switching mode to the new double channels switching mode byonly switching the fault communication port mutually. The front--end system also has some characteristics on its linkingmodes of the double channels, supporting the party--line communication of multiple protocols and synchronous/asynchronousmodes. and acquiring the power energy by dialing telephone and so on.
