三峡枢纽梯级调度交换网的组建

三峡枢纽梯级调度交换网由3种机型、6套交换机、10多部调度台，多种信令接口方式组成。担负着国调至三峡梯调，三峡梯调至三峡左岸电站，三峡梯调至葛洲坝大江电厂和二江电厂，三峡船闸至枢纽等有关单位的调度通信。文中以组网方式及信令接口为主，介绍三峡枢纽梯级调度交换网的特点及信令接口。

The cascade dispatching exchange network in Three Gorges

The pivot cascade dispatcher of Sanxia exchange network consists of three different types,six sets of exchanges,more than ten dispatchers platform and various signaling interfaces.It undertakes multi-links dispatching communication such as from national telecommunication center to Sanxia cascade dispatching center,from Sanxia cascade dispatching center to Sanxia to left-bank substation and to GeZhouBa main power plant and Erjiang power plants,and other relative nodes.This paper introduces the characteristics of signaling interfaces and the interconnection of cascade dispatching exchange network in Three Gorges.
