지중송전계통에서 시스순환전류 해석 및 저감방안

  • Published : 2001.11.01


This paper describes the analysis of sheath circulating current and various methods to reduce the large circulating current in case of operating cable system using EMTP/ATPDraw. And also, possible methods are proposed through a detailed analysis regarding cable systems by considering various electrical and environmental factors. It is evaluated that the proposed reduction methods can be effectively applied to reduce the large sheath circulating over current with the minimized electrical problems.
