A method and system and a computer program for improving reliability of a
centrally-controlled electrical protection system is provided. The method
includes identifying at least one component of the centrally-controlled
power distribution system, obtaining at least one of reliability data and
reparability data for each at least one component of the
centrally-controlled power distribution system, and constructing a
reliability block diagram for each functional category. The computer
system and computer program code segment are configured to implement the
method for improving reliability of a centrally-controlled electrical
protection system architecture based on sensitivity analysis.
