A cost/benefit analysis in feeder reliability studies

A computer-based method for predicting the cost/benefit ratios associated with distributed feeder reliability improvement projects is presented. The method utilizes component failure rates and feeder configuration in determining values for the reliability measures. The cost/benefit analysis is applied to an upgrade of a Pacific Gas and Electric Company feeder. This 21 kV underground feeder, designated Stockdale 2114, was upgraded extensively in 1985. It is shown that the cost/benefit ratios of the individual upgrade projects vary considerably and depend to a great extent on the strategy used in the upgrade program.<
