Reliability study for process bus based substation considering various practical process bus architectures

摘要

As it is important to evaluate the performance of the Digital Substation, So The objective of first part of this paper is to evaluate the reliability and availability of protection functions for practical substation architecture using RBD method based on different configuration. RBD is a success-oriented network simplifying the function of the system by showing the logical connections among system components. And in the second part we will go through the effect of system Reliability on the Protection systems applicability and methods to improve the performance of the Systems.
