Abstract
This chapter presents the methodology and results for the economic evaluation of an extensive DA project. The outage costs and benefits of the DA system are quantified by using standard mathematical expressions. An economic evaluation method based on value-based analysis and present worth analysis is performed to identify the most beneficial functions in the DA projects. Test results obtained in this chapter have indicated that the feeder automation (FA) is the most beneficial function to utilities. Therefore, the candidate feeders and number of switch for further FA extension is also conducted in this chapter. The results and expressions of this chapter can serve as the basis for the utilities' DA system implementation guideline. The results can also be used for cost-benefit analysis, return-of-investment, or possible performance measure of the DA systems.
