Communication System for Distribution Automation Using EPON

In electrical power industry, the distribution network is an important part of the total electrical supply system as it provides the final link between the bulk transmission system and the customers. And a reliable communication network constitutes the core of the distribution automation system (DAS). Although a number of communication technologies have been applied to meet the utility´s operational and planning purposes, there is no one-communication technology that is right for every situation. This paper proposes a novel communication method for distribution automation using Ethernet Passive Optical Networks (EPON). Based on centralized control scheme, a three-layer communication structure for DA is designed, which provides a good communication alternative for the DAS.
