This paper describes a method for predicting circuit breaker time-to-failures using a probabilistic operational model that incorporates generation capacity growth. Increases in generation capacity may cause fault current levels to approach or exceed circuit breaker ratings. This condition may increase the probability of a circuit breaker failure. Circuit breaker failures result in common-mode multiple...
Decisions on maintaining, repairing, refurbishing and replacing cable systems are usually a compromise between what technically is advised and what economically is feasible. To implement an optimal maintenance and/or replacement strategy, asset managers and/or maintenance engineers need appropriate tools to provide them with reliable information on the condition of the cable systems. Partial discharge...
Hidden failures in protection schemes, the traditional N - 1 security criterion and the introduction of the electricity market are usually major causes in the recent wide area blackouts. In the present work, we address the reliability analysis of power systems using the Generalized Stochastic Petri Nets (GSPN). The proposed modeling approach considers not only the most common failures of power system...
