The transmission of sampled value is an important component of serial communication between process-level and bay level in substation automation system. Electronic current/voltage transformers makes the digital transmission of sampled value possible. The substation communication network and latest international standard -- IEC61850 standard features was analyzed. Around sampled value transmission problems of substation processor level,and grasping the IEC61850 information model,analog sampled value transmission model,abstract communication service, and message format of sampled value was researched. A general steps of building analog sampled value model and transmission process in the substation is given, which will provide solutions for satisfying the requirement of collecting and transmitting distributed arrangement informationin digital substation.
