Cost benefit analysis of faster transmission system protection systems: Presented at the 71st annual conference for protective relay engineers

摘要

This paper analyzes the effects of reducing tripping times on the cost of a transmission system. A range of trip times are examined to demonstrate the difference in the initial price tag of a transmission system as well as the ongoing cost. The increased cost of a slower tripping scheme is analyzed by investigating the relationship between substation ground grid and transmission line neutral conductor sizing and cost.
