Construction of a Redundant Dispatching Exchange System Based on Dispatching Data Network

In order to provide better service to power dispatch,dispatching exchange network need to optimize network structure and to enhance network reliability.This paper analyzes the existing problems of Guizhou electric power dispatching network,and discusses the possibility of building a redundant dispatching exchange system using soft switch technology based on dispatching data network and secondary safety protection system.The construction scheme of soft switch system is introduced.The access methods of the main station and user stations and the plan for IP addresses and bandwidth are stated.The successful practice proves that soft switch voice system can be built on dispatching data network and secondary safety protection system.The advantages of soft switch system are analyzed and this paper also indicates that the development direction of dispatching exchange network is all-soft switch.
