Abstract: The cultivation of power system communication talents lags behind the development of power system communication field, so it is necessary to strengthen the cultivation of professional talents in universities for the development of power system communication. Therefore, it is very important to deepen college students’ understanding of power system communication and how to operate secondary terminal equipment of power system. This paper introduces a kind of comprehensive electric power system automation experimental platform, which is composed of various terminals, communication equipment, communication mode and master station. It can simulate the working process of WAMS system, distribution automation system and electricity information acquisition system. It supports a variety of communication protocols, such as 101/104, Modubus and GB/T 26865.2—2011. The combination of simulation and practical operation can deepen students’ understanding of the working principle and communication protocols of the actual power automation system.
