Substation reliability simulation model

Utility supply operational characteristics are used to reveal the possible significant differences between theoretical and actual reliability indices when component failures and restoration activities are not independent. A customized simulation model is described for assessing the reliability indices of an industrial substation configuration as a function of calendar time based on the historical utility supply data and an industrial substation´s operational configurations, loading patterns, and restoration activities dependent on the severity of the power interruption. The simulation model was applied to a radial industrial substation configuration. The historical reliability performance of the utility-industrial customer is considered as it relates to the theoretical expectations and changing utility and industrial facility operational characteristics
