Stja. Vermeulen et al., MODELING THE INFLUENCE OF PREVENTIVE MAINTENANCE ON PROTECTION SYSTEMRELIABILITY PERFORMANCE, IEEE transactions on power delivery, 13(4), 1998, pp. 1027-1032
Protection systems exhibit two important types of failures: failures t
o operate and unwanted operations. Both failure modes have been introd
uced in a model description designed for the evaluation of the influen
ce of preventive maintenance on protection system reliability performa
nce: The model description is constructed as a continuous time Markov
chain. The system states and the transitions between states are genera
ted in a general and systematic manner which makes it possible to appl
y the model description to a lot of different situations. Through an e
xample it is shown that (the quality) of preventive maintenance can ha
ve significant influence upon the reliability performance of a given s
ystem.
