摘要：The effect of all different kinds of feeder automation on power supply reliability is analyzed. Specific method of evaluating feeder automation scheme using net profit rate of investment is expounded from the view of practical engineering in this paper. The feeder automation scheme of the city of H is analyzed and calculated. The improved method of production and electricity ratio is used to calculate the loss of outage reduced by implementing feeder automation. The economy of different types of feeder automation in different power supply sections is analyzed and compared, and the optimal feeder automation schemes in different power supply sections are given. The results of the studies are of certain reference significance for the distribution network plan.
