Data communication plays an important part in the simulation training system of substations. The parts ot the simulation system achieve connection, real-time communication and data sharing with another. More actual senses are realized in order to meet more advanced training requirements. The architecture of the substation simulation training system is proposed; a data communica- tion program is developed to achieve the data communication of the substation simulation training system by using IEC60870-5-103 protocol, multi-threading technology and network communication technology. In order to make the relevant parts of the system react to another synchronously and effective interactive simulation is achieved. Furthermore, there are some examples to elaborate the development process of the thread function and the server network communication program. At the same time, the communication results of the data communication program are analyzed.
