摘　　要：电力调度通信系统的稳定、可靠直接关系到电力企业的安全生产。嘉兴电厂通过H20-20交换机中继组迂回路由、交换机相互级联的方法,将2套DDS-200调度通信系统搭建成一个双调度通信系统,大大提高了嘉兴发电厂调度通信的可靠性。文章着重分析了中继组路由迂回、2B+D接口方式的特点,详细介绍了双通道接入电力调度网和双调度交换机控制同一个调度操作台的实现方法。A stable and reliable power dispatching communication system is crucial for the safe operation of power enterprise. Jiaxing Power Plant sets up a dual-dispatching communication system by connecting two DDS-200 dispatching communication systems setting Harris 20-20 trunk group an alternative route and the mutual cascade of switches. This paper mainly analyses the features of alternate route and 2B＋D interface, and introduces the realization of the dualchannel access dispatching communication network and the operation console controlled by dual-dispatehing switches.
