Abstract
Reliability of IEDs in a substation is a critical issue in power system operation and in practice, use of different IEDs from different manufacturers has been causing many difficulties in maintaining reliability. In this paper, a new reliability enhancement scheme for a IEC61850-based substation automation system is proposed. It utilizes a redundant backup IED and software-moving on communication network. A fault detection technique based on pattern checking is also proposed. Reliability analysis of the proposed scheme is given as well.
