Abstract :
A directional comparison bus protection unit (DCBPU) can provide a high speed bus fault clearing in the IEC61850 process-bus environment. This technique is based on superimposed fault direction for each circuit connected to the protected bus. In this paper, the implementation and testing of a superimposed directional comparison technique for bus protection based on an IEC61850 process bus is investigated. Design, hardware implementation, and related issues of DCBPU are described. A unique test setup is proposed and developed for testing DCBPU, including merging unit simulator, traffic generator, prototype DCBPU, and Ethernet switches to simulate the real IEC 61850-based substation automation process bus. Test results are reported.
