IEC 61850 Standard Based MMS Communication Stack Design Using OOP

This paper deals with the MMS communication stack library based on IEC 61850 standard. IEC 61850 standard is communication protocol of substation automation for converting conventional copper-wired type to Ethernet based open architecture in digital method. With IEC 61850 standard, interoperability can be maximized. With IEC 61850, optimal use and prediction of troubles are done through real-time surveillance by substation system. Starting from European market, substation automation systems (Sass) based on IEC61850 are spreading trend. Trying to stay with the trend, communication stack library is needed. IEC 61850 standard consists of object, we adopt the strategy of using object-oriented programming (OOP) based on C++ language. Therefore we can take advantages of maintenance, management, alteration and reuse. For improving power of OOP method, we adopt design pattern, especially singleton pattern. With these two strategies, this paper layers the library into a dozen or more layer to provide developers ease of use. We simulate this library by making Microsoft Windows programs.
