Abstract

Methods are presented for modeling the failure and repair of transmission equipment and their impact on subtransmission system reliability. The methods account for arbitrary load variation and nonexponential downtime distribution for components. The effects of single independent outages common-mode outages and independent overlapping outages are studied. The results are used to identify conditions when nonexponentially distributed downtimes can lead to significant errors if the method of analysis does not take this factor into account
