Construction and evaluation on smart substation information integration scheme

Smart substation is an important part of the smart grid which represents the future direction of development of new technologies in the substation. This paper propose an smart substation information integration scheme based on the IEC61850 standard, and it can simplify the structure of the substation automation system, achieve information sharing of the common network and a seamless connection between the systems, then analyzes its real-time performance and reliability, and also provide a new way of thinking to build a unified, open, intelligent substation automation system.
