Abstract
With the economic development, the traditional substation control system cannot satisfy the current electric power requirement. It is necessary to effectively use the communication protocol in the substation automatic system. This article introduces the communication protocol in the first place. Moreover, it discusses the IEC 101 protocol characteristics, frame structure, and the overall summon transmitting in details. Then, the substation automatic system obtains the optimized analysis of hardware and software. At last, this paper provides part of the system core code, which has a positive effect to the software designer and substation maintainer.
