Abstract
In many power system applications, two of the most practical indices of reliability assessment are the system average failure rate and the average outage duration. This paper illustrates the development of these indices for two dissimilar units connected in series and in parallel. The equations for a restricted repair condition are developed using the frequency and duration approach and compared with the known results for unrestricted repair. The only parameter which is appreciably affected by restricted repair is the average system outage duration when the two units operate in parallel. This paper develops an approximate and simple expression to evaluate this parameter which provides results that are very close to those obtained by the complete equation.
期刊介绍：
IEEE Transactions on Reliability is a refereed journal for the reliability and allied disciplines including, but not limited to, maintainability, physics of failure, life testing, prognostics, design and manufacture for reliability, reliability for systems of systems, network availability, mission success, warranty, safety, and various measures of effectiveness. Topics eligible for publication range from hardware to software, from materials to systems, from consumer and industrial devices to manufacturing plants, from individual items to networks, from techniques for making things better to ways of predicting and measuring behavior in the field. As an engineering subject that supports new and existing technologies, we constantly expand into new areas of the assurance sciences.
