A Study on the Information Exchange Technology Between IEDs Using SOAP in Network Based SA System

In this paper, autonomous information exchange methodology is studied between IEDS using SOAP protocol based on XML and PtP communication. Inference-based solution of the IED identifies the faulted zone autonomously from free information exchange among IEDs, transmits the operation information to the above SCADA system, also determines whether it executes or not for commands from the above SCADA. Finally, Inference-based solution is implemented using MS Visual C++ MFC, MS SOAP and MS XML. Availability and accuracy of the design is verified from simulation reviews for typical distribution substation.
