    Abstract

    For power industry systems, reliability is related to the ability of the system to provide an adequate supply of electrical energy [2-5]. However, reliability related measures are fundamentally different to those used in traditional reliability practice. System reliability is related to the probability that a product/service will operate properly for a specified period of time under the design operating conditions without failure [1]. In standard reliability theory, this probabilistic perspective has been generally used to model and analyze the reliability of aproduct/service. Reliability related measures such as availability, mean time to failure, importance measures, etc. are also based on such probabilistic perspective. When considering electric power system reliability, researchers and analysts are interested in how component outages and repair rates affect the associated overall system rates. Primary interest is devoted to the quantification of system failures; this quantification is then translated to expected system outage rates, mean outage duration and overall downtime.
