Discussion and Reflection on the Application of IEEE C37.118.2-2011 Standard in Distribution Grids

I316 is an important way to build an intelligent distribution grids that the existing SCADA system and WAMS are integrated with each other in the distribution grids. Protocol fusion or conversion is the precondition of system integration. This paper, by comparing IEEE C37.118.2-2011 and IEC 60870-5-101/104, some functions of IEC 60870-5-101/104 are extended to IEEE C37.118.2-2011 in terms of data frames and command frames so that IEEE C37.118.2-2011 can adapt to the distribution grids.
