Implementing research for IEC 61850-based fault analysis system

With the maturing of the IEC 61850, utilities are beginning to implement substation automation systems (SAS) that are based on this new international standard. This paper describes such an implementing research for power fault analysis system on east china electric power group in China. In particular, it presents the idea of applying object-oriented methodology to architecture design and providing an open interface of IEC 61850 in the substation layer. Based on the idea and technique, some benefits are brought.
