IEC 61850 표준을 바탕으로한 임베디드 통신스택 SoC와 통신스택 라이브러리 구현

Abstract

This paper deals with implementation of a IEC 61850 communication stack SoC used in a SAS server and a client and IEC 61850 communication stack library used in the SoC. The proposed SoC is combined with a logic processor and an IEC 61850 processor. According to the definitions of IEC 61850 standards, communication services of SAS are divided mainly into four steps: SCL engineering, initialization, processing and communication step. The four steps above defined in IEC 61850 standards are designed by using object-oriented programing language; C++. The proposed IEC 61850 communication stack library is implemented and verified by being used to develop a server and a client program. By using the IEC 61850 one chip communication stack processor, the processor makes it easy to manage and repair an IED, and supports compatibility between IEDs of different manufacturers. By using the IEC 61850 MMS communication stack library, not only user’s development hours are reduced but also it contributes to the automation of substation.
