โœฆ Synopsis


This paper presents an analytical technique based on the device of stages for distribution system reliability evaluation. This technique models the aging of equipment in evaluating the reliability indices. The three main indices evaluated are failure rate, outage time, and average annual outage time for each load point. An additional set of indices (performance indices) is also calculated using these three basic indices and the number of customers/loads connected at each load point in the system. The most common performance indices are SAIFI, SAIDI, CAIDI, and ASAI. A computer program has been developed to implement this method on a DEC VAX-8800 computer. Finally, system studies are performed to evaluate the basic and performance reliability indices using various models.
