비상상태에서의 제주 ±80kV 60MW HVDC 운전 방안 연구

This paper presents the operation strategy of KEPCO(Korea Electric Power COporation) ±80kV 60MW Bipole HVDC system that will be applied between Guemak C/S(converter station) and Hanlim C/S in Jeju island. Unlike intertie HVDC system, this system is located in AC power grid inside. Therefore, the enhancement of system security related with line flow and bus voltages can be major operation strategy. In this paper, in particular, the optimal operation algorithm in the abnormal(not steady state) power system is presented and simulated.
