Mhj. Bollen, METHOD FOR RELIABILITY-ANALYSIS OF INDUSTRIAL DISTRIBUTION-SYSTEMS, IEE proceedings. Part C. Generation, transmission and distribution, 140(6), 1993, pp. 497-502
The method for reliability analysis of industrial distribution systems
presented in this paper combines a Monte Carlo simulation with an ele
ctrical network model. The Monte-Carlo simulation generates fail and r
estore events in stochastic components. The flexibility of the Monte C
arlo simulation made it possible to include ageing of components and p
reventive maintenance. As industrial loads are often sensitive to shor
t-duration voltage sags, the influence of these sags had to be include
d in the model. This is done by using the maximum permissible voltage
sag at the load nodes as an interruption criterion. The occurrence of
a short-circuit and the intervention by the protection are modelled in
detail. Mal-trips as well as fail-to-trip of the protection are inclu
ded. The method presented in this paper is suitable for industrial (an
d other) distribution systems where sensitive loads are present, where
maintenance of components is important and/or where the behaviour of
the protection influences the reliability.
