The performance requirements, network structure and data flow status of communication network in substation automation system are introduced. The principles and principles to be followed in the selection and design of communication network in substation automation system are discussed. The substations with different voltage levels and different levels of complexity Based on the analysis of Ethernet Carrier Sense Multiple Access / Collision Detection Mechanism (CSM A / CD), this paper proposes a scheme of communication based on embedded Ethernet. In this paper, we analyze the communication network of substation automation system Performance requirements, network structure and data flow on the basis of the discussion of substation automation communication network program selection and design must follow the principles given voltage level and complexity of the substation specific communication network program, and in the analysis of Ethernet Carrier Sense Multiple Access / Collision Detection (CSM A / CD) based on the proposed embedded-based
