The design of an Object-Oriented Embedded Platform for Substation Data Integration

With the development of technology in substation automation, more and more new application systems owned heterogeneous data have emerged. However, some information of these application systems cannot be utilized sufficiently by power enterprise management systems because there is neither design as a whole nor applied integrated platform of substation information. In this paper, An Object-Oriented Embedded Platform for Substation Data Integration (EPSDI) and a compatible interface scheme for legacy intelligent electronic devices (IEDs) and standard IEDs based on IEC 61850 is proposed. The software architecture based on multi-agent systems is realized and the balance between the stability and the performance can be achieved through the agile distribution configuration and publish/subscribe mechanism among agents. The method can bring a new feasible approach to propelling substation smooth digitalization based on IEC61850, because of its good application and expandability.
