Reliability and maintenance of electrical power system: Invited lecture

Abstract

Paper deals with the analyses of electrical power network reliability parameters connected to maintenance. Knowledge of the component reliability parameters in power networks is necessary for the reliability computation and also for reliability-centered maintenance system. Component reliability parameters are possible to retrieve only with accurate databases of distribution companies. Such a database includes records of outages and interruptions in power networks. Maintenance influence the indicators evaluating interruptions — maintenance time in fact means unavailability. There are analyses of interruption indicators improvement, modern techniques like Live Working and Reliability Centered Maintenance in this paper.
