DESIGN OF BROADBAND DATA COMMUNICATION NETWORK FOR ELECTRIC POWER SYSTEM

This article introduces the principle and technology of the broadband data com munication network for the electric power system . Based on the comparison of the features of three kinds of techniques,i.e. IP over ATM,IP over SDH and IP over Optical/WDM,the mode of IP over ATM is selected according to the actual conditions of the power system.Then the technology of IP over ATM combining with multi- protocol label switch MPL S is introduced to m eet the requirements of the electric power communication network.The schem e of constructing Guizhou broadband data comm unication network for the electric power system using this method is expounded. The structure,levels and topological graph of the network are given.
