Abstract
The effect of the fault could be propagated to healthy region when the fault on the power system is not cleared in time. In order to enhance reliability of the protective relay, a dual and/or backup system is adopted for the power system protection. The IEC61850 has become an international standard of the substation automation system for interoperability between heterogeneous IEDs from different vendors. This paper introduces a reliability enhancement technique for the substation automation system using characteristics of the IEC61850.
