Abstract

Reliability assessment of a power system having an integrated component is provided by retrieving individual component failure rates associated with individual components of the integrated component. A failure time is modeled based on the individual component failure rates associated with individual components of the integrated component. Individual component maintenance times are retrieved associated with individual components of the integrated component. A maintenance time is modeled based on the individual component maintenance times associated with individual components of the integrated component. A reliability assessment is determined based on the interconnectivity of components of the power system, the modeled maintenance times, and the modeled failure times.
